Abstract

By comparing the forecast product by the GRAPES_SDM model and the observed data of dust-storm weather in Xinjiang in the springs of 2008-2013, we tested the forecast product with synoptic verification method. By analyzing mean error, error standard deviation and root-mean-square error, the characteristics of error distribution of numerical forecast in Xinjiang are shown, and the possible sources of the systematic and non-systematic error are analyzed. The results showed that the 2-m height air temperature and 10-m height wind speed error mainly came from the uncertainty of the initial conditions and the inconsistencies of the resolution of observation and prediction. We also proposed some suggestions on improving the GRAPES_SDM model forecast accuracy.
