本文论述东亚梅雨锋的大尺度环流及其次天气尺度扰动,提出了以下的论点;东亚梅雨是印度季风体系与北太平洋哈得来(或信凤)体系之间的过渡带中产生的现象;梅雨锋是半热带、半温带性质的天气系统;梅雨锋暴雨的发展与梅雨锋上次天气尺度扰动有关。文中给出了东亚梅雨锋的大尺度环流及其扰动的概念模式。 |
英文摘要: |
The large-scale circulation of Mei-yu system over East Asia has been reviewed from dynamical climatalogical view in.this paper, Following arguments have been pointed: Mei-yu phenomenon is occurrence in the transition region between the Indian Summer Monsoon System and the trade wind (or Hadley) system over the tropical North Pacific; Mei-yu front belongs to a semi-tropical and semi-extratropical weather system; the heavy rain occurred at Mei-yu front is caused by the disturbances of subsynoptic systems to the front. The conceptional models for the large-scale circulation and various subsynoptic disturbances of Mei-yu system have been given. |
