2007年江苏稻飞虱阶段突增与低空环流特征耦合分析
|
摘要
利用2007年江苏稻飞虱和天气背景(700hPa和850hPa流场和温度场)资料,分析了2007年江苏稻飞虱突增时段的低空环流特征,从而探讨了江苏稻飞虱大发生的平均环流背景、风速分布。得出:影响2007年江苏稻飞虱突增环流形势,一是受西南暖湿气流影响,有明显的西南低空急流存在;二是由于北上或西进热带气旋外围而产生东北气流。700hPa和850hPa上西南气流的大风速范围对2007年稻飞虱北迁区域具有很好的指示意义,850hPa上气旋外围大风区影响范围对2007年稻飞虱的回迁具有较好的关系。本文为研究江苏稻飞虱的大发生时间、影响区域和回迁情况提供了思路和方法。
By using the data of rice Planthopper of Jiangsu and weather background(stream and temperature field on 700hPa and 850hPa),the low level circumfluence characteristic during immigration peaks was analyzed in Jiangsu 2007.The average circumfluence background and wind velocity distribution that lead to rice planthopper rapid increasing were discussed.The results showed that there were two kinds of circumfluence to arise Jiangsu rice planthopper rapid increasing in 2007.Firstly,there was obvious southwest low level jet due to southwest warm-humidity air stream.Secondly,there was northeast stream by the tropic cyclone moving to north or west.The range of southwest airflow(gale area) in 700hPa and 850hPa took on well showing meaning to rice planthopper area.There was some relation between the gale range in 850hPa of tropical cyclone and back immigration of planthopper in 2007.The results provided references to forecast the rapid increasing time,influence area and back immigration condition.
