Why aren't all clouds rainy?

Have you ever flown a plane through the clouds, or maybe climbed high up a mountain and watched the clouds swirl around you? Then you should have a good idea of ​​what a cloud is: just a collection of fog.

As you know, air always contains water vapor. In summer, there is more vapor in the air because the temperature is higher. When there is a lot of vapor in the air, a slight decrease in temperature is enough for it to begin to condense (that is, water droplets form). In this case, we say that the air is saturated. Just a slight decrease in temperature is enough for water vapor in saturated air to condense. So when saturated warm air rises to an altitude where the temperature is lower, condensation occurs and clouds form. Water molecules combine to form countless little droplets.

What happens when all those water droplets in a cloud meet a mass of warm air? They evaporate - and the cloud disappears! Therefore, clouds are constantly changing their shape. The water contained in them constantly turns into water, then into steam. The water droplets contained in the cloud have weight, so gravity pulls them down and they sink lower and lower. When most of them fall, they reach the warmer air layers, and this warm air causes them to evaporate. Therefore, clouds are obtained from which it does not rain. They evaporate, and the droplets do not have time to reach the earth's surface.

But if we assume that the air under the cloud is not warmer? What is very damp air? Then the droplets will increase and increase in size, and the condensation will be stronger and stronger. Pretty soon all the little droplets will turn into big drops reaching the ground and it will rain!

 Random interesting fact from the Great Encyclopedia:

How did music come about?

Have you ever walked through the woods and come across a small stream, merrily babbling along the path? It sounds like music, doesn't it? When the rain drums on the roof, a bird gently sings - isn't that music?

When a person began to observe what was happening around him, he found that music was everywhere. And when he wanted to express great joy, when he wanted to jump, shout, expressing what he felt, he heard music in himself, although, perhaps, he could not yet put it into form. Gradually, man learned to sing - this was the first music created by man. What feeling do you think a person would like to express in a song in the first place? Happiness? Yes, the happiness of love. The first songs were love songs.

On the other hand, when a person was face to face with death, which horrified him, he expressed these feelings in various types of songs, for example, dirges or funeral songs, church hymns. Therefore, love and funeral songs were the first music created by man.

Another kind of music appeared with the development of dance. The man needed accompaniment during the dance. So he clapped his hands, snapped his fingers, or beat the drum. The drum was probably the oldest instrument that man invented to produce sounds. It is so ancient that we cannot trace its beginnings in history, but it is found in all ancient people throughout the world.

The most ancient wind instruments created by man were whistles and reed pipes. Whistles were made from bone, wood and clay. From this developed the flute. This is a very ancient instrument, the Egyptians owned it more than 6000 years ago. Stringed instruments followed suit. Did you know that they already existed in Ancient Egypt?

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Earth Asteroid Shield 20.02.2012

Established in January 2012, an international group of scientists and engineers launched the NEOShield project. Over the next three and a half years, she will work to develop means to protect the Earth from asteroid impacts.
The exact date of the last fall of a large asteroid to Earth is unknown. But the surface of our planet still bears traces of cosmic bombardment, like the 6 km Nordlinger Ries crater in Bavaria.

A total of 13 organizations from research institutes and industrial companies will jointly explore technologies to prevent asteroid and comet impacts, in particular, ways to use special spacecraft to remove dangerous asteroids from orbit.

On the trajectory of approach to the Earth, asteroids usually have a speed of 5 to 30 kilometers per second. Existing examples of asteroid impacts, such as the 1,2-km Barringer crater in Arizona or the Tunguska region in Siberia, demonstrate the damage that space "guests" can cause. However, even smaller asteroids can cause massive destruction if they fall on a large city. So, the crater in Arizona was formed as a result of the fall of an object about 50 meters in diameter. Thousands of similar asteroids have been discovered over the past 50 years, which means that dangerous impacts with Earth are likely to occur every few hundred years.

In order to change the orbit of dangerous celestial bodies and prevent a collision with the planet, it is required to apply enormous energy at a strictly defined time. The NEOShield project will study the issues of determining the composition of the most dangerous asteroids, including using space probes.

One of the main tasks of the project is to develop technologies for the destruction or deflection of an asteroid. According to NEOShield experts, this can be achieved using a nuclear explosion or a space towing vehicle. The effectiveness of such methods remains to be seen.
It is possible that, based on the results of the work of the international group, "exercises" on asteroid defense will be carried out - using the appropriate space technology. In addition, the defense plan developed by NEOShield could be used against the asteroid Apophis, which will dangerously approach Earth in 2029.
