Overview of the water and water cycle. Evaporation is the process in which a liquid changes to the gaseous state at the free surface, below the boiling point through the transfer of heat energy .

Evapotranspiration or ET. 62% of precipitation that falls on the continents is evaporated. Understanding and predicting climate change. Q=P-ET. P-ET is the water available for use. ET "loss" supports ecosystems and agriculture. Sun warms ocean water causing it to EVAPORATE. Water vapor CONDENSES to form clouds. Clouds become very heavy before beginning to PRECIPITATE. Precipitation collects in rivers, lakes, and oceans. The sun warms ocean water…. Daily Operations and Accounting. Daily estimates are used for operations and accounting at certain reservoirs, but not all. Estimates are typically based on pan evaporation measurements or reference evapotranspiration.
