| Abstract: | Based on the 168 hours forecast of 500hPa geopotential height field of ECMWF, extrapolation forecast and local weather rhythm, intending 10d circulation situation can be confirmed. Then the intensity of weather process can be forecasted by analyzing the range of westerly index and local terrain. |
