Evidence suggests that on the basis of deviations in heights from zonal mean three area indexes are calculated for the Urals, Lake Baikal and Ehuocik areas, respectively,which can well express the daily evolution in intensity and position for the 1998 summer Eurasian blocking highs and bear close relationship wit.
结果发现 ,利用纬偏值作为基本量可以计算出乌拉尔山地区 ( 2 5～ 80°E)、贝加尔湖地区 ( 80～ 1 2 5°E)、鄂霍茨克海地区 ( 1 2 5～1 70°E) 3个区域阻塞高压的面积指数 ,该特征值能很好地揭示 1 998年夏季阻塞高压强度和位置变化的逐日演变特征 ,并且与我国 1 998年夏季降水的分布有重要的联系。
The results could be match the index data of the typhoon area index.
