Penmen

Penman refers to a method used in hydrology and meteorology to estimate the potential evaporation from a water surface, such as a lake or soil. It combines factors like temperature, humidity, wind speed, and sunlight to calculate how much water could evaporate under ideal conditions. This approach helps scientists understand water cycles, manage water resources, and predict drought or flood risks. The Penman equation is a widely accepted model because it considers both the energy available for evaporation and the influences of atmospheric conditions, making it a comprehensive tool for water and climate studies.
