The Nature of Rain from the Scientific Perspective

What is the Nature of Rain

After the director of one of the American radio stations got wet because of the autumn rain, the radio program “Weather forecast” appeared. Information that is formed due to weather data providers turned out to be relevant, since it is always useful to find out whether it is worth taking an umbrella today and whether it is necessary to leave home, because, for example, in Portugal, rain and wind are a good reason not to go at work. Let’s find out more about the physical nature of rainy weather.

Scientific Definition and Physics

Rain is formed by the condensation of water vapor, which is collected in clouds, transforming into clouds, from which droplets fall to the surface of the earth. This phenomenon is a consequence and an integral part of the water cycle in nature.

What Are the Reasons of Rainy Weather?

Climatology and meteorology (sciences that are directly interested in any precipitation), identify 4 main causes:

  • Rising air movement;
  • The presence of water vapor in the air, in an amount sufficient to form rain;
  • Meeting warm and cold air currents;
  • The presence of elevated landforms.

Various Types of Rain

  • Usual is just rain without any pronounced signs, it has average power, average duration. As a rule, it falls in a warm period.
  • Showers are sudden and powerful. In a short period, a huge amount of water is poured on the ground. Rainfall is often accompanied by thunder and lightning and usually occurs in late spring and summer.
  • Lingering rain is a sign of autumn. It is characterized by exceptional duration – from several hours to several days, slowness, low temperature.

  • The light rain is characterized by transience. It begins abruptly and ends unexpectedly.
  • Snow rain often coincides with the first snow and occurs in late autumn – early winter.
  • Rain with hail. Despite the pieces of ice, sometimes of very large sizes, such rain falls most often in the summer, not in the winter. This rain is usually short, powerful and often dangerous.

Records

  • The champion in the amount of precipitation on earth is the village of Cherapundi. The average is 11,000 millimeters. This settlement is located on the southern slopes of the Himalayas. The factor contributing to constant rain is the high humidity of the air and the upward movement of air through the mountains.
  • The antipode champion is the South American Atacama desert, where the average rainfall varies between 1-3 mm per year.
