摘要
本文利用西沙群岛、东沙群岛、南海沿岸陆地及船舶等探空资料和航空、卫星、地面雷达等天气报告资料,对8616号台风的动力学特征进行了计算和分析。结果表明,该台风风速分布不对称,气旋性最大切向风位于台风右前象限,风速的垂直切变随台风的加强而减弱。最强的流入位于台风南半圆300hPa以下,流入最大值在700hPa附近。高层最强的反气旋流出在150—100hPa,流出主要位于台风北半圆。此外,该台风的垂直运动分布与台风的发展及所处的位置有密切的关系。
Dynamic properties of typhoon Wayne are computed and analysed with soundings from Xisha and Dongsha Islands, coast of The South China Sea and ships, as well as weather reports from airplanes, satellites and ground radars. The result shows that Wayne is asymmetric in its wind speed distribution. Its maximum tangential cyclonic winds locate in the right-forward quadrant. Its vertical wind shear decreaes with the strengthening of the typhoon. The strongest inflow in confined to the portion below 300 hPa in the southern semi -circle. The maximum inflow is around 700 hPa and the greatest upper -level anticyclonic outflow is near 150-100 hPa. The outflow is mainly in the northern semi - circle. Additionally, the vertical motion of Wayne is found to be closely related to its development and location.
