Forecasting the weather
Forecasting the weather

Sometimes it is vital to determine the weather, at least for the next couple of hours. How to do it? Yes over the clouds.

Did you know that in England only at the very end of the 20th century was the law abolished according to which weather forecasters (weather forecasters) it was supposed burn at the stake holy inquisition?

When you watch TV and the TV presenter happily promises beautiful weather, and in the window behind her you can see it raining, you really regret that other laws do not work or have been canceled for some reason.

Seriously though, sometimes it is vital to determine the weather, at least for the next couple of hours. How to do it? Yes over the clouds. Not very accurate, but the percentage of correct predictions is quite high. And when there is no choice, such a prediction is still better than nothing.

A girl can trust forecasters, but a real man should be able to predict the weather himself.

The number of clouds in the sky is estimated on a ten-point scale. If the whole sky is covered with clouds without any gaps, then it means ten points of cloudiness. If the number of gaps between clouds is equal to the number of clouds, then the cloud cover is five points. If there are a couple of clouds in the sky, then this is one, two points. Do not worry about the accuracy of determining the amount of clouds. Approximately identified and okay.

Let's start by classifying the clouds. The clouds in the sky are arranged in three tiers:

Lower tier, the height of the lower boundary of the clouds above the ground from 100 meters and above. Clouds are nimbostratus, stratocumulus and stratocumulus. From the name you can see that the clouds are in the form of layers. Nimbostratus clouds cover the sky completely, ten points, without any gaps and water the earth with a long, gray, heavy rain, of varying intensity and possibly with short interruptions. Under such rainy clouds there are sometimes torn-rain clouds, they fly in the wind in such huge flakes.

If you observe such stratus clouds, then the rain will last for a long time. At the same time, look at the birds, if the birds go about their business and do not pay attention to rain and dampness, then you have correctly identified the clouds and you can easily predict with a high probability that the rain will last for a long time.

Of stratus clouds, it's such a gray, dense layer all over the sky, 10 points, it doesn't rain. In fact, stratus clouds can develop into stratus clouds or stratocumulus clouds, but they themselves do not promise rain. Isn't it. That in winter, rare snow can fall from the stratus clouds.

If there are many gaps in the clouds, the cloudiness is 7-8 points, and the clouds themselves are in the form of many large cakes, then these clouds are called stratocumulus. Stratocumulus clouds can be reborn or transformed into other clouds, but they themselves practically do not affect the weather. Consequently, the weather will not change for the next couple, three hours.

On the lower tier, clouds of vertical development also arise, these are cumulus and cumulonimbus.

There are three types of cumulus clouds:

  • cumulus flat (this is when the height of the cloud is less than its width.
  • cumulus averages (height is equal to width)
  • and Cumulus vigorous (the height of the cloud is much greater than its width).

All cumulus clouds are good weather clouds. Lying on the beach, it is interesting to watch how a column of powerful cumulus cloud gradually grows from a tiny flat cumulus cloud. A powerful tornado develops inside such a cloud. The tornado is not visible from the outside, but the strength of this tornado is gigantic, and if some conditions allow, then a powerful cumulus cloud develops into a cumulonimbus cloud.

The lower side of such a cloud turns black, and the upper border of the cloud extends almost beyond the atmosphere and shines in the sun so that it is painful to look. The top of a cumulonimbus cloud can be shiny and smooth, such a cloud is called bald cumulonimbus or with light cloudy outgrowths in all directions, it is a hairy cumulonimbus cloud.

Cumulonimbus clouds produce heavy rainfall, often with thunder and lightning. Sometimes cumulonimbus clouds grow so large that they begin to cover the entire sky. Over land, the dimensions of such giant cumulonimbus clouds, although significant, look like dwarfs compared to cumulonimbus clouds over the sea. Over the sea, more precisely over the tropical regions of the oceans, such clouds are already a natural disaster, and there this phenomenon is called a typhoon.

Typhoons are known to have a proper name and the troubles that a typhoon can bring are widely known. But it all started with an ordinary harmless cloud over some coral island.

A cumulonimbus cloud above the ground can also cause trouble. For example, hail agricultural crops. Hail can be large. There are cases when hailstones were the size of a hen's egg. With such a hail it can break the glass in the windows, break through the slate on the roofs, and spoil the lining of cars.

But in general, rain showers from cumulonimbus clouds are short-lived. Although intense and abundant. It is about such rains that they say they passed in a strip or thundered, thundered, sparkled. sparkled and not a drop of rain fell. Birds do not like to urinate under such rains and sit in shelters.

The middle cloud layer is divided into Altostratus and Altocumulus. The base of the clouds is above one kilometer. Unlike lower clouds, altocumulus clouds are slightly smaller and sleeker in size, and altostratus clouds are usually translucent to the light of the sun. Well, very rare snow, separate, beautiful and small snowflakes, can fall from high-layered clouds in winter. Middle clouds are a sign of stable weather for the near future.

The upper tier consists of cirrus, cirrocumulus and cirrostratus clouds. Cirrus clouds in the form of thin and delicate entangled threads. Cirrocumulus clouds resemble astrakhan fur. Tiny and pretty curls. Cirrus and cirrocumulus clouds do not promise bad and rainy weather. But sometimes cumulonimbus clouds accompany.

On the contrary, cirrostratus clouds may precede altostratus and, as a result, nimbostratus. Cirrostratus clouds are translucent and form a circular halo (halo) around the Sun or Moon. You need to cover the sun with your hand to see the gallo and at the same time protect your eyes.

I hope now you can accurately predict what the weather will be for the next two hours?

Correct answer: "And the devil only knows."
