中国沙漠域での乱流輸送量の観測 -HEIFE沙漠観測点での乱流輸送量の観測結果について-

Abstract

We made the turbulent fluxes observation in a sand desert in China (around 40ﾟN, 100ﾟW) during Intensive Observation Period of HEIFE (HEIho revier basin Field Experiment) in 1991.The results of the observation show the condition of the heat and water transport in the arid aria.Roughly saying, the latent heat flux is 20% of the net radiation flux in the August observation, and 5% in the October observation.The integrated evaporation after rain became the same amount of rainfall only in 4 days both in August and in Octobar observation, and the evaporation continued more.The specific humidity at groud surface shows daily variation in same phase of temperature, but the relative humidity there shows large variation in the reverse phase of the temperature.
