GEO E111 Lecture Notes - Lecture 17: Background Radiation, Transpiration, Dew Point
Document Summary
Places with high temperature experience high humidity due to high evaporation and air having high capacity to hold moisture. Places with low temperature have low humidity due to low evaporation and air having low capacity to hold moisture: source of moisture. Areas near water bodies e. g. kisumu and mombasa experience high humidity due to evaporation of water from the water body. Places near thick vegetation also have high humidity due to evapo transpiration. Areas far away from water bodies such as the middle of deserts have low humidity. Areas receiving heavy rainfall also have high humidity: air pressure. There is high humidity at low altitudes because high pressure compresses air warming it increasing its capacity to hold moisture and also causes high evaporation. There is low pressure at high altitudes because air expands and cools thus reducing its capacity to hold moisture: latitude.
