We propose a method of volume heating of a vertical air column by the vertically directed microwave radiation at the frequency of the spectral atmospheric-absorption line. The heating efficiency is estimated for the case of the molecular-oxygen absorption band near a frequency of 60 GHz. The proposed heating method can lead to the formation of new convection structures in an air column. Absence of natural ascending airflows with stationary heating over the entire flow length is noted.

大气吸收线上微波辐射对垂直空气柱的体积加热

我们提出了一种通过垂直定向的微波辐射以光谱大气吸收线的频率对垂直空气柱进行体积加热的方法。对于分子氧吸收带接近60 GHz频率的情况，估计了加热效率。所提出的加热方法可导致在气柱中形成新的对流结构。注意到在整个流动长度上没有自然的上升气流，并且没有固定的加热。
