旱涝是关乎国计民生的大事,是气象学者研究的重点。南亚高压作为夏季南亚地区对流层上部平流层底部强大而又稳定的半永久性大气活动中心,它对我国夏季天气气候变化有着重要的影响。从20世纪60年代初,针对南亚高压特征及其与我国夏季旱涝关系的研究,就一直进行着。本文着重总结了近10多年中国内外关于南亚高压特征及其与我国旱涝的研究工作的新进展,在此基础上,进一步提出了南亚高压今后研究的新问题和新趋势。
To exist as a strong and steady high pressure system,at the top of the troposphere and the bottom of the stratosphere over the southern Asia in summer,South Asia High(SAH) has a significant impact on the weather-climate,specially,the distribution of summer drought and flood in China.From the 1950s,the studies about the features of SAH and its influences have been carrying forward.A review is made for the studies of SAH activities and its influences on summer drought and flood in China in recent more than 10 years.Meanwhile,the existing questions and future directions of SAH research are further put forward.
