FIELD EXPERIMENT AND NUMERICAL SIMULATION OF INVERSE HUMIDITY OF ATMOSPHERE OVER DESERT NEAR OASIS

The characteristics of specific humidity profile of atmosphere over desert near oasis,observed in HEIFE,are given.And the structure of specific humidity profiles of atmosphere over oasis and desert near it is simulated by a developed mesoscale numerical model of soilplant-atmosphere continuum.In the simulation,inverse humidity of atmosphere over desert near oasis is shown numerically,patterns of three kinds of typical specific humidity profile and law of presence of them are obtained,and the mechanism and physical process,forming the inverse humidity of atmosphere,are explained.
