Rainfall


Precipitation can be superficial or atmospheric non-superficial.

Precipitation superficial occurs when condensation occurs near the surface. Atmospheric precipitation not superficial occurs when condensation happens away from the surface. Fog, dew and frost represent the superficial precipitation. Snow, hail and rain represent non-superficial precipitation.

Precipitation of ice crystals that originated from the crystallization of atmospheric humidity at or below 0 ° C. Snow accumulation in cold regions (polar and high mountains) is responsible for the formation of glaciers.


Snow: It is a metrological phenomenon that consists of falling ice crystals.

It consists of ice. It is formed by convective currents (vertical movement of the air), which conduct the water droplets to the higher and colder layers, where freezing occurs. It can cause serious damage, especially in agriculture.


Hail formation occurs when strong air currents carry tiny droplets of water at altitudes above the freezing point inside the clouds.

It is a layer of ice where dew becomes when the surface temperature reaches zero degrees.


Frost in the Botanical Garden of Curitiba; the phenomenon is common in the coldest capital of Brazil

These are the drops of water on plants or objects that condense on the surface as the air cools overnight.


Dew - atmospheric precipitation in which water vapor condenses and settles overnight and in the form of very fine droplets over the vegetation of certain bodies exposed to the open air.
