摘要 本文着重讨论了6月500hPa亚洲中低纬环流特征与浙北丰枯梅雨的关系以及以3月环流特征量为主体建立丰枯梅雨的长期预报的问题。分析发现:6月500hPa环流变高场出现“X”型和“V”型是丰梅特征,出现“M”型是枯梅特征,梅雨丰枯环流特征对比鲜明。用3月环流特征量为主体作梅雨丰枯的长期预报效果良好。 The characteristics of the general circulation at 500 hPa over the middle and lower latitudes of Asia during June were discussed with relation to the wet/dry Meiyu season in the northern part of Zhejiang province, thus leading to the long-range forecasting of the wet/dryMeiyu season by using the characteristic values of the general circula-tion in March. It is found that the wet Meiyu season is characterized by 'X' and'V' patterns of the isallohypse field at 500 hPa during June, while thedry Meiyu season by 'M' pattern, showing a sharp contrast. Good resultshave been proved by using the characteristic values of the March circula-tion to forecast the wet/dry Meiyu season.
