摘要
The forecast of precipitation,height,temperature,divergence and water vapor divergence during a rainfall process in Northeast China during June 13-14 in 2012 were analyzed. The results showed that the rainfall process in Northeast China on June 13 and 14 in 2012 was mainly caused by the typical northeast cold vortex at 500 h Pa,southwest low-level jet at 850 and 700 h Pa,and surface cyclone. The rainfall forecast valid in 60 h was obviously better than those valid in 36 and 84 h,and the forecast error mainly resulted from the prediction error of vertical water vapor transportation.
