摘要
利用四川温江和云南大理近地层通量观测系统数据,采用涡动相关法等计算方法对比分析了四川温江和云南大理的湍流通量变化特征以及湍流通量与大气稳定度的关系.结果表明:不同地区的湍流通量都具有明显的日变化特征,但能量的分配方式具有明显差别.不同地区不同下垫面的湍流通量随大气稳定度的变化情况一致.
Based on the date of the PBL observation system at Wenjiang in Sichuan and Dali in Yunnan,the characteristics of turbulent flux,the relationship between turbulent flux and atmospheric stability were analyzed by using the eddy correlation method.The results show that turbulent flux displayed obvious diurnal variations in the different area,but the Bowen ratio was different.The variation of turbulent flux accompany with atmospheric stability was the same at different area and underlying surface.
