青藏、伊朗高原春夏季高层热力异常与我国夏季气温的关系

Penman formula was used to calculate the evapotranspiration in the upper valley of the Huanghe river since 1980.The variation tendency of some climatic factors, such as evapotranspiration, sunshine duration, air temperature, air saturation deficit and etc, were analysed.

利用彭曼公式计算80年代以来黄河上游流域蒸散量，分析了该地区蒸散量、日照时数、气温、空气饱和差等气候因子的变化趋势，并着重研究了诸因子对蒸散量的影响。

A Study of Upper Air Temperature Change

高空大气温度变化研究

The analysis demonstrates that: ( 1) The upper temperature inversion which is the subsidence inversion, appears together with the relatively strong deviating north air stream near to its top.

分析表明：（1）上层逆温与位于其顶部附近较为强劲的偏北气流是相伴出现的，其性质属下沉逆温。

From the diagnosis we can find that the cause of Winnies transformation is the intrusion of cold air from the middle-upper troposphere and the warm temperature advection in the lower.

通过对物理量的诊断分析发现，对流层中高层冷空气的下沉入侵以及对流层低层的暖平流是热带气旋变性的原因。
