Characteristics of Radiation and Energy Budget over an Oasis under Different Synoptic and Irrigation Conditions in Summer

By using data of "The Oasis System Energy and Water Cycle Field Experiment" in Jinta Oasis in the summer of 2005,the characteristics of daily variations of surface radiation and energy budget over the oasis under different typical synoptic conditions are analyzed,including a clear day,a cloudy day and rain day in an extreme arid region and two abnormal soil moisture conditions.There are many differences among the features of radiation and energy budget under different conditions.There was unbalance of energy observed in the experiment.The energy deficit was between 20%~30% in a clear day and about 17% in a cloudy day.
