砂漠からの蒸発についてHEIFE砂漠観測点での年間蒸発量の推定

Abstract

The Sino-Japan Cooperational Resaerch Project HEIFE was held in 1991 and 1992 in the arid area in Gansu Province in China. The result of turbulent observation in the sand desert shows that the evaporation seems to be larger than the rainfall.The bulk parameterization for the sensible heat flux was developped to study annual and seasonal variation of the heat budget.And the evaporation is estimated from the heat budget. The estimation shows that the lOdays averaged evaporation is almost always larger than rainfall, and the total evaporation is about 300mm in 1991, while the amount of precipitation is 91mm.
