摘 要:
应用广西1960年以来地面88个观测站日平均气温、降水量、相对温度、均风速、总云量等气象资料,以及1970-2001年ECMW F再分析资料850hPa比湿和垂直速度资料,分析南海夏季风异常早晚的广西气象要素特征。结果表明：南海夏季风偏早,广西地面气温偏低,季风爆发当候广西气候特征往多雨方向发生变化,而爆发之后气候趋于较正常状态;南海夏季风偏晚年,爆发前6候,地面气温高,在季风爆发后5候内降水量较多;南海夏季风偏早、偏晚与广西多数固定月、季时间尺度的气温、降水量的关系无明显增加线性相关。[著者文摘]

Abstract:
Based on the ECMWF reanalysis global specific humidity and the vertical velocity at 850- hPa for the period 1961-2000 and the data of mean daily temperature, precipitation, relative temperature, mean wind speed and total cloud cover from 88 observation stations of Guangxi since 1960, the feature of the meteorological element relative to the abnormal early （late） of the South China Sea summer monsoon （SCSSM） is analyzed. Results show that the surface temperature is lower in the year with the earlier SCSSM and the climatic characteristics of Guangxi changes from less rain to more rain in the pentad of SCSSM onset and then trends to the normal after that. While in the year with the later SCSSM, the surface temperature is higher before six pentads of SCSSM onset and the precipitation is more in the five pentads after the SCSSM outbreak. The relationship between the earlier （later） SCSSM and the temperature and the precipitation in month and season time scales increasing is not much significant.[著者文摘]
