Comparison of Spring Forecasting Ability between GY-WRF and GRAPES in Danghe South Mountain

The Plateau Numerical Weather Forecast System (GY-WRF) was evaluated for its ability to forecast spring weather in Danghe South Mountain. forecasted temperature, relative humidity, and wind were compared with GRAPES using data from four automatic stations March April 2022. results showed that GY-WRF had the smallest mean absolute error (MAE) each factor at station 4, a small MAE speed 2, but slightly larger direction. direction, similar trend GY-WRF. better predicting diurnal variation of while effect on forecasting minimum temperature. Both capable pre-dicting direction conversion station, being speed.
