Abstract. This study uses the high-resolution GRAPES_Meso (the mesoscale version of the Global/Regional Assimilation and Prediction System) to simulate a severe squall line hailstorm in Shandong province. The accumulated precipitation, radar reflectivity, and cloud hydrometeor properties simulated using a modified double-moment microphysics scheme are compared with observation. Results show that simulations captured the basic character of this squall line hailstorm. The simulated accumulation precipitation and radar reflectivity are comparable with the observation. The cross-section of the dynamic, microphysical, and radar reflectivity structures of the simulated hailstorm was analyzed. The simulated hailstorm has shown a reasonable result in both macrostructure and micro hail production rates. The development of the simulated hailstorm is consistent with the conceptual model of hailstorm evolution. Results imply the ability of high-resolution GRAPES_Meso on forecasting hailstorm.

Short summary
Hailstorm is one of the severe disaster weathers for agricultural countries. Hail microphysics processes have been added in the double-moment microphysics scheme in the operational model GRAPES_Meso and a severe squall line hailstorm is simulated. Compared with the observation, simulation results can capture the basic character of this squall line hailstorm. Results imply the ability of high-resolution GRAPES_Meso on forecasting hailstorm.
