利用2005年夏季在金塔绿洲附近获得的沙漠和绿洲中心点的湍流、辐射等观测资料,分析了这一时段内各观测点的主要能通量变化规律。结果表明,在沙漠点分析能量闭合时必须考虑土壤热储的作用。而在绿洲中心点,虽然从平均日变化上也可看到与浅层土壤热储较为一致的不平衡能量项,但二者在8:00～11:00间存在显著差异。分析指出此时的土壤增温可能是由于深层土壤中的水蒸气向上移动进入到浅层土壤并凝结放热造成的。
Based on the observation data of turbulence and radiation in desert and oasis center obtained in the vicinity of Quinta Oasis in the summer of 2005, the variation law of the main flux of each observation point in this period is analyzed. The results show that the effect of soil thermal storage must be considered when analyzing the energy closure in the desert. In the oasis center, although the average daily diurnal variation can also be seen with the shallow soil thermal storage more consistent energy imbalances, but the two in the 8: 00 ~ 11: 00 there are significant differences. The analysis indicates that the warming of the soil at this time may be caused by the upward movement of water vapor in deep soil into shallow soil and the condensation of heat.
