TL;DR: In this article, results from the operational prediction of Haiyan by a tropical regional typhoon model for the South China Sea are analyzed, and sensitivity experiments are conducted to study the impact of certain physical processes such as the interaction between stratus and cumulus clouds on the improvement of the typhoon intensity forecast.

TL;DR: Using a 2-km-resolution WRF model, along with its single-layer urban canopy model and Thompson bulk-parameterization microphysics scheme, numerical simulation of a convective rainstorm is executed over Guangzhou city in the Pear River Delta (PRD) to investigate the impacts of urban environments(including urban land use changes and urban air pollution-enhanced cloud droplet number concentration) on the convective precipitation as mentioned in this paper.

TL;DR: In this article, a review summarizes the general developments of the operational mesoscale model system based on the Global/Regional Assimilation and Prediction System-Tropical Monsoon Model (GRAPES-TMM) at the Guangzhou Regional Meteorological Center.

TL;DR: In this article, the authors attempted to improve the nowcasting of GRAPES model by adjusting the model initial field through modifying the cloud water,rain water and vapor as well as revising vapor following rain water.
