We all know a reckless summer shower, anda quiet autumn drizzle, and an unexpected warm, damp rain. Rains go at any time of year and almost in all corners of our planet. And what kind of rain? Let's figure it out.
Rain as a phenomenon of nature
Rain is a type of precipitation, falling outon the ground in the form of water droplets. Why is it raining? It falls out of the clouds, which contain drops of water and ice crystals. At a temperature (in clouds) below 0 degrees, ice crystals grow, which become larger and heavier and fall out of the cloud. At the same time, drops of water are frozen to the crystals.
Falling to the ground, the crystals begin to melt in the warmer lower atmosphere, turning into rain.
Types of rain
Rains differ in size of water droplets, according tointensity and duration. Depend on the season, atmospheric pressure, air temperature and many other circumstances. In scientific classification, rains are divided into three types:
- rain shower,
- drizzling rain,
- lingering rain.
A storm shower consists of the largest and heaviest drops. This rain begins and ends suddenly. It does not happen long and is often accompanied by a thunderstorm, and sometimes hail.
A prolonged rain is a medium intensity rain, but the longest of all. It is the prolonged rains that can last several days, and in the tropical regions they last for months.
The rainy rain sometimes does not even look like rain in the usual sense for us. It consists of very small drops, under which it is impossible to get wet, which do not even leave traces on the puddles.
In addition to these main species, such rains are also known:
- Exotic. Rains, in which animals, fish, plants, seeds and grass (as well as other objects) fall from the sky along with drops of water.
- Color rains (red, black, yellow) are formed due to impurities to water droplets of dust or pollen.
- The icy rain consists of drops in an icy shell. Smashing at the surface of the earth, such drops cover everything, on what get the crust of ice.
- Acid and radioactive rains contain impurities of harmful substances.
- Virga, or rain under the clouds. It is a rain in which water drops do not reach the surface of the earth.
