Hence, many centres of inversion intensity is discovered in the time-height section. Thickening of the inversion layer usually has the characteristic of burst, the top of the inversion layer is in periodic waveform.

In this paper, a typical radiation inversion in the north suburbs of Peking is analysed. It is found that inversion intensity is not only fluctuating with time but also sandwiched with height. Hence, many centres of inversion intensity is discovered in the time-height section. Thickening of the inversion layer usually has the characteristic of burst, the top of the inversion layer is in periodic waveform. The time-height variation of turbulent intensity in the inversion layer is incontinuous, the transfer of momentum and heat is gusty with time and sandwich with height.The authors believed that these characteristics are mainly due to interaction between wind and temperature in the inversion layer.

本文分析了北京市郊一类典型辐射逆温。发现逆温强度不仅随时间的变化是起伏性的,而且随高度是分层的。所以,在时-空剖面图上通常呈现为多个分离的逆温强度中心。逆温层厚度的发展常常具有爆发性特征。逆温层顶多为周期性波动状态。逆温层内部湍流强度的时-空变化是不连续的,动量和热量的输送在时间上是阵性的,在高度上是分层的。 作者认为这些特征主要是由于逆温层内部风场和温度场之间的相互作用决定的。

Typical features of the development of the inversion and the formation of the jet during surface cooling are obtained. Finally, several parameters are calculated and analysed and compared.
