摘要
用一个β平面的准地转模式和一个高分辨率的f平面准地转模式,实施了6组试验,研究了初始台风切向风速水平廓线对台风路径和强度的影响。结果表明:切向风速峰值区狭窄,最大风速半径较小的廓线,与偏西北方向的路径以及强度维持或增强相对应;峰值区宽平,最大风速半径较大的廓线,与北折转向的路径以及强度衰减相对应。
By means of a β-plane quasi-geostrophic model and a high resolution f-plane quasi-geostrophic model,six experiments are carried out to investigate the effects of initial tangential wind velocity profile on typhoon track and intensity.Results show that the profile with a narrow region of peak value of tangential wind and a smaller radius of maximum wind is favorable to a north-western track and the maintenance or enhancement of typhoon;on the contrary,a north-turning track and weakening of typhoon happen.
