摘要
阿荣旗暴雨主要集中在7—8月,以7月最多,占65.9%,8月次之,占18.2%。31次暴雨过程主要以对流性降水为主,占近64.5%。物理量场:925 hPa和850 hPa比湿平均值分别为13.2和11.6 g/kg;925、850和700 hPa相对湿度平均值分别为94.5%、94.0%和88.6%;假相当位温平均值334.4 K,总温度平均值为46.6℃;500和850 hPa温度差和K指数异系数较小,平均值分别为23.8℃和36.3℃。
Arong Banner rainstorms were mainly concentrated in July and August,accounting for 65.9% at most in July, followed by 18.2% in August. The 31 rainstorms were mainly convective precipitation, accounting for nearly 64.5%. Physical quantity field: the average specific humidity of 925 and 850 hPa is 13.2 g/kg and 11.6 g/kg respectively;The average relative humidity of 925, 850 and 700 hPa is 94.5%, 94.0% and 88.6%. The average pseudo equivalent potential temperature is 334.4 K, and the average total temperature is 46.6 ℃;The temperature difference and K-index coefficient of 500 and 850 hPa are small, with average values of 23.8 ℃ and 36.3℃ respectively.
