Precipitation

The terrestrial surface possesss about 510 million km, being 71%coberta for oceans, seas, rivers, lakes and glaciers and 29% of lands emersas or continents (Africa, America, Asia, Antarctica, Europe and Oceania) and islands. Temperature is defined as the degree of heating of a body, in the case, of atmospheric air. It is amount of present heat in the atmosphere. It is presented as an indirect heat, therefore it is radiated of the surface for the atmosphere, since the energy of the Sun heats the surface of the Land and this radiates heat for air. The condicionantes factors of change of the temperature are the altitude, the latitude, the maritime proximity of the sea and chains the water in the atmosphere: Precipitation is the amount of water that falls in the surface of the Land in the solid state (snow, hail) or eliminates (rain). Thus it is called because the water vapor goes up, it forms clouds, it is condensed and later if it precipitates. Express rain gauge and if in millimeters measures with a called instrument.

Types of rain: – Frontal: rain more lasting and less intense than if of the one in the contact of a cold front with a cold front. – Orographic or of relief: they occur in similar way to the one of the convective one, therefore the condensation if of when air reaches cold and high layers. The precipitation occurs when it arrives of horizontal form at the mountain ranges and mountains and if he condenses. – Convective: fast and strong rain, that even comes with thunders and some times with hail. It occurs when air finds cold layers in its vertical ascensions, if precipitating the condensation after. Humidity represents the amount of water vapor contained in the atmosphere. It is the result of the evaporation and perspiration and is express in percentage. Maritime chains are portions of water that if dislocate in the oceans.
