采用广州有限区域数值预报模式，以登陆台风“黄蜂”(0214号)为例，研究海南岛屿地形和对流凝结潜热对登陆台风“黄蜂”的影响。
Taking landfall typhoon Vongfong (0214) as an example, the effects of Hainan island topography and convective condensation heating are studied by using Guangzhou limited-area numerical forecast model.
对流单体主要在海拔较高的山脊处生成，并向低海拔地区移动传播，传播的速度和方向主要与地形和中高层风速风向有关。
Convective cells formed at high altitude plots firstly and then spread to lower altitude area, and the speed and directions of cells 'spread depend on terrain factors and upper level wind.
初步揭示出地形对两类对流天气的影响机制，其结果对进一步分析研究和准确预报强对流天气具有重要意义。
Consequently, the mechanism of topography effect on convective weather has been revealed. The result is very important for the analysis and forecasting of strong convective weather.
