Orographic rains are typical of regions where the air saturated of vapor d? water forms clouds in the neighborhoods of the hillsides windward, this in case that he is typical of the littoral regions that the Mountain range of the north-eastern and Southeastern Sea of Brazil understands where the portion windward of the hillside well humid must to orographic precipitations, and the hillside the lee-side is practically dries and unprovided of precipitation, therefore the orographic barrier of the Mountain range of the Sea hinders that humid air and the formed clouds, obtain to exceed lean the lee-side, in the truth in this feio of the relief the clouds suffer process from adiabtica decompression, being thus dissolved. (AYOADE, 1986) the ciclnicas precipitations or frontals are originated through the zone of meeting of air masses with distinct thermodynamic characteristics and variation of humidity, the overlapping of the hot and humid air mass in relation to a cold air mass and dry, for example, make with that humid and hot air if cools, forming cloud and condensation nuclei, thus, ciclnicas precipitations are less intense of what the convective ones, but they can last more time, therefore while to exist the zone of disturbance of the air masses, rain will be able to coexist. Soon, the different types of precipitation are related directly the formation origin of the cloud, where the main elements are the relief, the high intensity of solar radiation and the zone of contact or meeting between air masses de with distinct thermodynamic characteristics and humidity. Such characteristics are found of direct and indirect form under specific ambient conditions and can in accordance with oscillate the geographic localization of the region in the globe.. San Antonio Spurs does not necessarily agree.
