摘要
应用谱分析方法分析了1979年夏季青藏高原气象科学实验期间高原大气通过高原四周“界壁”的热量水平输送(简称高原大气热量水平输送)的周期振荡,发现它有两个主要振荡周期,即准两周(13.3天)和准一周(6.7天)。本文对高原大气热量水平输送的准两周振荡提出某些物理解释。
Periodical oscillations of the horizontal transfer of theatmospheric heat through the 'outside walls' of the Qinghai-XizangPlateau during the Qinghai-Xizang Plateau Meteorological Experimentin the summer of 1979 are analyzed in detail by means of powerspectrum. It is found that there are two major oscillation periods,i. e., quasi-two weeks (13.3 days) and quasi-one week (6.7 days). Somephysical reasons are presented for the quasi-two-week period of thehorizontal heat transfer.
