摘要
使用1961~2013年广西80个气象观测站的日降水资料和NOAA OLR、NCEP/NCAR风场、高度场再分析资料。分析持续性区域性暴雨异常年份大气低频活动特征,得到结果:广西持续性区域性暴雨异常多(少)的年份,中高纬度地区高空大气温度30~60天周期振荡强度弱(强),位置偏北(南),广西及其以南低纬度地区OLR 30~60天周期振荡有明显(相对不明显或不连续)的向东传播。
Based on the daily precipitation data at the 80 meteorological stations in Guangxi, NOAA OLR data and NCEP / NCAR monthly reanalysis data during 1961-2013. The possible impact of the low frequency oscillation on the continuous regional rainstorm over Guangxi is studied, the results show that: when the continuous regional rainfall is more( less) than usual over Guangxi, the weak(strong) and the north(south) location of 30-60 d oscillation about 500 h Pa air temperature over the middle and high latitudes, and the obvious( not obvious or not continuous relatively) eastward propagation of 30-60 d oscillation about OLR over the low latitudes.
