Document Summary
Water vapor = most important element in the atmosphere. Amount of wv (gas) in the atmosphere is highly variable: ranging from 4% (near. Wv is very important when considering atmospheric stability. Evaporation: latent heat is absorbed [liquid -> gas] Condensation: releasing latent heat [vapor -> liquid] Infiltration: into the soil: not the same across the board (soil in austin is not the same as soil in arizona, here in austin we have many rocks in the soil (edwards aquifer) ***the biggest issue in texas over the next 100 years is water*** Latent heat absorbed: evaporation (a cooling process, melting [solid -> liquid, sublimation [solid -> gas (dry ice)] Latent heat released: freezing [solid -> liquid, condensation (a warming process) [gas -> liquid, deposition [gas -> solid] Ratio of the air"s (cid:374)atural (cid:449)ater (cid:448)apor co(cid:374)te(cid:374)t co(cid:373)pared (cid:449)ith the a(cid:373)ou(cid:374)t of (cid:449)ater (cid:448)apor required for saturation at a given temperature.
