Bubble puddles during rain. Bubbles in the puddles during the rain. Bubbles in puddles - what does a sign mean for men and women

Everyone loves a warm summer rain! How merrily its drops knock on the roofs, clapping on the broad leaves of burdock and pulling on delicate flower petals. Puddles spill on the asphalt, everything becomes clean and fresh. Fine!

Do you know why bubbles sometimes appear in puddles when it rains? Some people think that the bubbles indicate that the end of the rain is near. Others believe: since the bubbles have appeared, the rain will be long. In fact, both are wrong. The appearance of bubbles is explained by the fact that a raindrop hits the surface of the water and seems to bounce off it. This forms the thinnest water film, similar to a dome. Under this small dome of water, like under an umbrella, air remains. So on the surface of the puddle and get a bubble.

In order for the bubbles to be noticeable and to remain on the surface of the puddle for a long time, the raindrops themselves must be large. And such drops occur during downpours, which usually end. Therefore, many people believe in the sign of the imminent cessation of rain after the appearance of bubbles. But why is there another sign - that the bubbles promise a long rain? Perhaps this is due to the fact that after a heavy downpour, another rain immediately begins - smaller, but lingering.

Do you already know that there is atmospheric pressure on Earth? It is due to the fact that air presses on us. And it presses hard! We do not see the air, but the force of its pressure could even crush us. But don't be scared, it won't happen. Inside us, too, there is pressure, which is equal to atmospheric pressure.

You probably want to ask: what does atmospheric pressure have to do with it? The fact is that the appearance of bubbles in puddles depends not only on the size of the drops, but also on the air pressure. When it is high, large raindrops hit the water surface and, repelled from it, form columns rather than bubbles. This is how pressure is related to raindrops.

Of course, when you grow up and read a lot of books, you can learn a lot of interesting things about different rains. And today you have found the answer to the question: why do bubbles sometimes appear in puddles when it rains.

Bubbles in puddles during the rain - what does this sign mean

Summer downpours, in contrast to the long and dull autumn ones, are more often associated in our minds with the cheerful tapping of drops on the window glass, washed greenery and streams of water on the pavement. Anyone who did not have a chance to splash through puddles during warm rain in childhood and step bare heels on bubbles jumping up here and there, definitely missed something in his life ... Why, by the way, do they appear? Let's find out. And at the same time we will find out what the signs say about the bubbles in the puddles.

Cause of blisters

It is useless to look for this funny natural phenomenon during a drizzle - in order for the water to bubble under your feet, several variables must converge at once.

First, the droplet size. When one of them falls into a puddle, forming a small funnel for a split second, water splashes up from the resulting hole. Its edges collapse, capturing a small particle of air, and a bubble runs along the surface of the puddle. It is clear that the larger and heavier the drop, the harder it will hit the surface of the water, which means that more bubbles will appear.

Bubbles need a real downpour

Secondly, the wind. Or rather, its absence. While the drops are flying vertically down from the cloud, the force of impact on the water increases, and the bubbles are large and strong. But as soon as the wind deflects the flight of a small projectile, the drops begin to strike across the surface of the puddle and dissolve in it, failing to raise the “wave” of the desired height.

And finally, atmospheric pressure. When it is raised, the falling droplets bounce off the puddle for a moment before dissolving into it, resulting in splashes instead of bubbles.

What do they stand for?

Surprisingly, folk omens cannot agree on what bubbles in puddles mean. Some argue that this is a direct promise of the imminent end of the rain: they say, now everything will pour out and the sun will come out. Others, on the contrary, are convinced that bubbling puddles promise protracted bad weather. Who is right?

Heavy rain usually doesn't last long

And those and others. On the one hand, large drops usually fall from cumulus clouds, which are not very large in themselves. This is usually what summer thunderstorms are like - it swooped in, quieted down, whipped bubbles in puddles and subsided.

On the other hand, cumulus clouds are often followed by nimbostratus clouds. And here you can’t count on a quick end to bad weather: once it starts, a quiet and fine rain can drizzle all day.

Most often, signs are advised to pay attention to the size of the bubbles. The larger and stronger they are, the longer the bad weather will last.

Signs about bubbles in puddles are changeable and rarely give accurate predictions. But is it worth worrying about it? As you know, "nature has no bad weather." And in the rain, it's so nice to sit by the window with a cup of hot tea and even meditate a little, looking at the bubbles bursting in the puddles.

Bubbles in puddles during the rain: a sign

The ability to notice the smallest details of natural phenomena and establish connections between them became the basis for the appearance of folk signs. Some of them have a clear scientific justification. One of them is bubbles in puddles. People paid attention to their appearance several centuries ago, and not so long ago the facts noticed by the people received a logical explanation.

True, many data are rather contradictory and require additional explanation. After all, some argue that large bubbles occur before the imminent end of precipitation. Others claim that the bubbles are for prolonged precipitation, which will annoy until the evening, and possibly last for several days ahead.

What do the bubbles in the puddles say

Bubbles in the puddles

Today, like many years ago, bubbles that appear in puddles during rain are considered a sign of prolonged bad weather. The rain may increase, it may slow down, but it will not stop for a long time. It is likely that prolonged precipitation will disturb more than one day.

This sign is known to everyone, so the bubbles that appeared in the puddles are perceived by many as an alarming sign and are preparing for tiring cloudy weather and tedious rain. At the same time, the inhabitants often hope that the omen will not work, and the sun will soon come out. On the possibility of establishing sunny weather when it's raining and bubbles appear in all puddles, we will discuss below.

Scientific explanation of the phenomenon

Why bubbles in puddles

Scientists, explaining the bubbles visible in the puddles during the rain, name several reasons for this phenomenon.

1. Low pressure, which not only promotes bubble formation, but also ensures cloudy weather for a long time. In this case, two huge fronts collide.
2. Large droplets that can overcome the surface tension of water. A drop, falling on the surface of the water, destroys it and forms a recess - a kind of funnel. A particle of water splashes out of this recess, covers the air bubble, enveloping it. Large drops occur during showers and downpours formed from high cumulonimbus clouds, and such natural phenomena cannot abruptly change into clear weather.
3. No wind if air masses moving near the surface of the water, they would press on the surface and prevent bubbles from forming during rain. In addition, a strictly vertical flight is necessary for a strong blow. If there is no wind, then there is no reason for the weather to change.

This sign is typical for central Russia, in the southern regions powerful downpours can begin suddenly and just as suddenly break off, replaced by a bright sun.

The meaning of bubble sizes

It is widely believed that bubbles in all puddles can portend the imminent end of the rain. This is really possible if large bubbles appear in puddles, this is a sign of short-term heavy rain. Similar signs are typical for thunderstorms. At the same time, it should be taken into account that large bubbles show the rapid end of this shower, but it can be followed by another with a small time interval.

Small bubbles predict a protracted bad weather that will last for several days. A small lingering rain can periodically stop for a short time, and then start again. But the total duration of rainy weather will be at least 2 days. To find out when to wait for the end of the rain, remember the appropriate signs.

Signs of stopping rain

If the weather has cleared up outside the window and there is no longer the strength to watch the constantly pouring streams of rain, they recall everything that is known about the onset of clear weather after a bad weather. Obvious signs of approaching sunny days can be considered the following:

• Rainbow in the sky. Rainbow in the afternoon - to the rapid cessation of rain. Rainbow in the morning - to prolonged precipitation. Such a sign becomes even more effective if the arc has shown itself completely or there are two or three of them side by side.
• Time to start raining. If the first drops hit the ground in the morning, the bad weather will end before lunch. If in the afternoon - wait for prolonged rainfall.
• Strong wind. He will carry away the clouds, and the precipitation will stop.
• Birds singing, their desire to fly. If during the rain the singing of birds begins to sound, they try to fly from place to place, it means that the sun will soon come out. Chickens also behave calmly, calmly walk under the drops falling from the sky, if the precipitation is soon completely over.
• The behavior of spiders, which, when it rains, begin to weave a patina, is considered a sign of the approach of sunny weather.
• Large drops and short thunder. This is a sign of the imminent end of the thunderstorm and the subsequent break in precipitation. True, this does not mean that then a fine rain will not start again.

So folk signs not only consider huge bubbles in puddles to be signs of stopping rain. Rather, on the contrary, there are other more accurate signs, and large bubbles are a dubious sign that is interpreted in two ways and has several contradictory nuances.

Bubbles in puddles during the rain - a sign

Folk signs and beliefs often help people predict the weather. Such predictions have been formed and tested for centuries and therefore they can be trusted. One of these predictions is the sign of bubbles in puddles during rain. This belief belongs to the category of weather, and can be useful both for gardeners and summer residents, and for those who like to spend time in nature and want to know in advance how long the bad weather will last.

Folk signs about bubbles in puddles

Many people argue whether the formation of bubbles in puddles indicates prolonged rain, or vice versa, this means that the bad weather will end soon. According to the sign, the rain with bubbles will be protracted, and in last resort and it may not last more than one day.

Our ancestors knew that the formation of such a phenomenon as a bubble promises only prolonged bad weather and were absolutely right, because its formation requires a certain atmospheric pressure, which happens when rain clouds and do not think to dissolve. And this means that precipitation will fall for a long time. Atmospheric pressure, which regulates the movement of warm and cold air fronts, and explains how long a storm will last. If two extended and slow-moving fronts collided, it will not be possible to wait for the sun and heat soon.

So the sign about bubbles in puddles has a scientific justification, and not even one. In addition to atmospheric pressure, for the formation of a bubble, it is necessary that the raindrop be large enough. Only in this case, it will be able to break through the surface tension of water. Large drops, as a rule, occur during showers and thunderstorms, and this in itself indicates that bad weather can drag on. Although, there are exceptions to this rule, for example, in the southern regions, bad weather often begins suddenly and ends quickly.

British scientists are somewhat late in resolving this issue, and this is precisely their area of ​​​​application of interest. In their place, immediately in the first experiment, he placed a bowl of distilled water in the middle of the puddle.

A bubble made of only water is unstable and bursts quickly. In order to stabilize its condition, some surfactants, such as soap, are dissolved in water. A common misconception is that soap increases the surface tension of water. In fact, it does just the opposite, reducing the surface tension to about a third of that of pure water. When a soap film is stretched, the concentration of soap molecules on the surface decreases, increasing the surface tension. Thus, the soap selectively strengthens the weak areas of the bubble, preventing them from stretching further. In addition to this, the soap keeps the water from evaporating, thus making the bubble life even longer.

A large raindrop falls on the surface of the water and forms a deep funnel. The funnel "collapses". And now a bubble with air enclosed in it has formed on the surface. The walls of the bubble shell "hold" due to the forces of surface tension of water. These forces increase, for example, when the water is soapy. If rain fell on a soap puddle, then not just rainbow-colored long-lived soap bubbles would form, but foam.

Smaller raindrops have a different fate. They also form depressions on the surface of the water, but not as deep, and they do not "collapse". Sometimes there are "water nails" - vertical thin fountains that appear in the center of the depressions. Especially impressive look "water nails" in heavy rain at night with a bright flash of lightning.

All bubbles look about the same. The shell of the bubble looks like a hemisphere. The spherical shape is explained by the fact that the sphere of all volumetric bodies has the smallest area, and the smallest area is required by the principle of minimum potential energy (every system at equilibrium is in the state in which its energy has a minimum value).

The spherical shape and surface tension affect the excess pressure that air forms inside the bubble compared to atmospheric pressure.

folk omen"bubbles in puddles - to a lingering rain" is absolutely true. Water is constantly evaporating from the walls of the bubble. During a heavy downpour or when the air humidity is close to 100% overcast, the evaporation of water from the walls of the bubble is negligible. This circumstance prolongs the life of large bubbles, which are numerous during a good summer rain. When the air humidity is low, the water evaporates quickly. In dry air, a thin layer of the water bubble wall would disappear almost instantly.

For the formation of more or less stably existing several seconds of bubbles in puddles, a combination of two factors is necessary, the first, as rightly indicated above, is the size of the drops (the bubble is formed as follows - a large drop pushes through the water film in the puddle, leaving behind an air "channel" that "collapses behind" back "of the drop, but for this the drop must be massive enough). And of course, in order for the life of the bubble to be sufficient, 100 percent air humidity is necessary. (It does not always happen).
In addition to these main facts, the existence of bubbles, in principle, can be influenced by such factors as the depth of the puddle, its composition, the presence of factors that destroy bubbles (wind with sand, for example, happens near children's sandboxes, I saw it.).
In the autumn light rain, there will be no bubbles. In the summer in a thunderstorm - yes.

In principle, everything that is written above is true. I would also add the fact that in order for the bubbles to appear (and / or be stable, that is, there is a noticeable time for us), it is necessary to stabilize them. Stabilization can be achieved with the help of surfactants contained in puddle water. The more of them - the easier the bubbles form and the longer they exist. There are more surfactants in one puddle, and less in the other, respectively, there will be more bubbles in the first one (surfactant content may be negligible, but the effect of this is large - since surfactant molecules concentrate on the surface of the bubbles, and those surfactant molecules that are in volume big role do not play). Remember that water with dissolved washing powder foams easily, when ordinary water practically does not foam. And if you put a basin with a solution of washing powder in the rain, then there will be much more bubbles in it than in any natural puddle.

The biggest soap bubble

The water doesn't have to be hard! To reduce the salt, the water must be boiled well and allowed to settle.

Recipe number 1, the easiest:
- water, soap (domestic laundry or glycerin), grate, the proportion is as follows: 10 parts of water to 1 part of soap, the proportion is approximate, of course. For strength in this water solution add glycerin or a solution of sugar with gelatin.

Recipe number 2
- 100 gr. any dishwashing detergent
- 300 ml of water,
- 50 ml of glycerin.

Recipe number 3
- 300 ml hot water,
- 150 ml of glycerin,
- 10 drops ammonia,
- 50 gr. any powdered detergent.
Mix all this and leave to infuse for 2-3 days. After the solution has been infused, strain it and refrigerate for 12 hours.

Recipe number 4
- 50 ml of regular transparent shower gel,
- 50 ml of water,
- 1/2 teaspoon of sugar.

How to check the quality of the soap bubbles turned out, or not? A bubble with a diameter of 30 mm should live for at least 30 seconds, or dip your finger in a soapy solution and quickly pierce the soap bubble, if the bubble does not burst, then you have the right solution.

Rain is beautiful at any time of the year. In summer, we are happy to enjoy the coolness and freshness after a downpour, the autumn heat brings peace and tranquility to our lives, sitting by the window with a cup of our favorite hot drink, we plunge into dreams and thoughts. There is no such person who has never asked himself the question - why are there bubbles in the puddles during the rain? The answer is known from childhood - this is a sure sign of a prolonged downpour. Whether this is so, no one can say because different sources report the sign in a completely different way.

A long time ago people began to notice natural phenomena and associate them with events in life. The impossibility of giving a clear justification for the appearance of bubbles on the water surface - people dated to the number of signs of prolonged downpours or an imminent cooling. So why do these bubbles appear and does the time at which this “mysterious” phenomenon occurs affect the sign?

Modern look

IN modern society it is not customary to pay attention to signs, for us they are relics of the past. Everything can be explained scientifically. Whether there are bubbles in the water or not depends on many different factors.

1. When the rain is lightly drizzling, then there are no bubbles at all. The largest droplets occur only after the air temperature drop outside, mixing of warm and cold fronts occurs.
2. In summer, during a thunderstorm, you can always notice large bubbles. During the day, the earth warmed up a lot, so warm air currents emanate from it, on the contrary, it’s cold at the top, then the downpour will be heavy, but will not drag on for a long time.
3. When the atmospheric pressure is low, there are a lot of bubbles, and they are in no hurry to burst.
4. The size of the drops - the larger, the stronger they hit the water, forming a kind of funnel into which air enters.
5. Lack of wind - a strong hurricane blows off droplets, preventing them from hitting the surface of the water.
6. Thanks to the increased atmospheric pressure, droplets bounce off puddles, and splashes are obtained.

Believe it or not?

What beliefs are associated with such a natural phenomenon? One sign says about a long and lingering rain, but there is a directly opposite statement, so what to believe? Note is true in both cases, but with different components. Bubbles during rain will be if:

• low pressure;
• the weather was hot;
• hovered all day.

Bubbles should not be expected: if there is an influence of atmospheres or a strong wind.

Weather

Everyone needs rain: both nature and man. Everything comes to life after watering, it is important to understand - where do rain clouds come from? Sun rays their heat can turn any liquid into steam. Evaporation comes from everywhere: from rivers, seas, lakes, ordinary puddles.

Droplets, turning into steam, rise high, reaching the highest mark - merge into a cloud. The clouds, hovering above the earth, are waiting for their time, as soon as the drops become so heavy that they cannot stay in the sky, they will spill onto the earth.

The influence of prediction at different times of the year

As you know, all natural phenomena among the people are associated with signs. I would like to know common signs bad weather to prepare in advance for surprises. Often, in the summer period there are short-term rains, and in the autumn-spring bad weather is of a protracted nature. And yet - how to do without weather forecasters, and to predict the further development of events yourself? The notes of our great-grandmothers related to balls in puddles during the rains will come to the rescue.

Large, beautiful bubbles are harbingers of the imminent end of a thunderstorm, small bubbles that do not burst for a long time - bad weather will be long. If the bubbles are of different sizes and there are a lot of them, it will rain for a week, at least. Large, rapidly disappearing bubbles - portend a cold snap for the next few days.

In autumn, we are wary of large bubbles that have appeared on the puddles - this is a sure sign of bad weather, the duration of which will drag on for a long time. So, it's time to get umbrellas, hats and unfinished books from the shelves, a great time for depressive individuals who love to watch the autumn drop. In summer, bad weather is only a joy, there is an opportunity: childish and frolic under warm water. Measure how in childhood all the puddles.

Harbingers of rainy days

Even before the rain, you can clearly find out how long the bad weather will last and when there will be a thunderstorm, we will be given clues: animals and birds.

1. Swallows flying low above the ground portend rain for the evening and the next day. In fact, the birds do not know about the upcoming bad weather, it's just that the midges that the birds feed on begin to fly closer to the ground.
2. Sparrows that bathe in the sand do such procedures on the eve of precipitation.
3. Pay attention to pets - cats, for example, will sleep all day before a storm, and dogs will sit at the door with a sad look.
