Document Summary
Diverging winds: air that moves downwards = dry conditions. Converging flow: hit air moves upward = rain conditions: this cools air because it is raising, cooled brings precipitation. Middle finger = high and low precipitations. The confluence (meeting) of free open water & transportation from plants . Measure of the concentration of water vapour in the air. Lots of wind moves vapour: humid days = saturated air will not take up more vapour = limited. Evapotranspiration: wind, put a face down once it accumulates a lot of vapour it wont increase, put a cup face up moist air is moved from wind = a lot of evapotranspiration. Plants move water through systems, when plants are under stress because it hasn"t rained plants stop photosynthesizing(close stomata) because they will lose water and wilt. (biologial controls) * balance of precuipatation and evaptransipration can etermine ecosystems chracteristics. Everything between the raindrop hitting the earth & it becoming a part of water systems.
