About: Penman equation

An Entity of Type: WikicatEquations, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The Penman equation describes evaporation (E) from an open water surface, and was developed by Howard Penman in 1948. Penman's equation requires daily mean temperature, wind speed, air pressure, and solar radiation to predict E. Simpler Hydrometeorological equations continue to be used where obtaining such data is impractical, to give comparable results within specific contexts, e.g. humid vs arid climates.

  • Penman公式，或譯為彭門公式，最早用於描述從開放水表面的蒸发量（ Evaporation，E ），由Howard Penman在1948年提出。 Penman公式需要日平均温度、风速、气压和日射量來預測蒸发量。經推廣後也可應用於估算植物和地表的蒸发量。 (zh)
