中文摘要:
      春季,冷空气进入华南以后,青藏高原以东往往在低空出现一层较薄的冷空气垫。在高空平直的西风环流下,沿南支西风急流带,有低压槽在冷空气垫之上东移,地面高气压区域中常有低压槽和锋生出现。本文查考了1958-1962年3-5月华南地区这类天气过程,并讨论了这类天气形势下的降水和雷暴的短期预报。
英文摘要:
      In spring there offen remains a layer of cold air above the ground of the east of the Tibetan Plateau after the invasion of cold air in South China.At this time if a trough in the south branch of the westerlies moves eastward over this cold cushion,then there offen appears a trough and frontogenesis in the region surface high.This paper deals with this type of weather process occurred in South China in the months of March to May of 1958-1962.Further the problem of forecasting the precipitation and the thunderstorm activity occurred in this weather process is discussed.
