这研究介绍一个新方法识别敏感区域,它由为台风调用潮湿的潜在的涡度(MPV ) 的否定异例是坚定的适应观察。否定 MPV 的区域是对称的不稳定性区域并且能为台风作为敏感区域被拿,这被发现适应观察。在 2008 的三台风, Nuri, Fung-wong,和 Fengshen,在 MM5 的帮助下被模仿模型。这些台风很好在开始的 12 个小时被模仿,这被显示出。把调查基于这些, MPV 的计算顺序被执行。结果证明 MPV 的否定最大值总是绕为所有盒子的台风眼睛,它意味着敏感区域总是也在他们附近。
This study presents a new way to identify the sensitive areas, which are determined by invoking the negative anomalies of moist potential vorticity (MPV) for typhoon adaptive observations. It is found that the areas of negative MPV are the symmetric instability areas and can be taken as sensitive areas for typhoon adaptive observations. Three typhoons in 2008, Nuri, Fung-wong, and Fengshen, were simulated with the help of MM5 model. It is shown that these typhoons are well simulated in the first 12 hours. Based on these investigations, the calculations of MPV are carried out sequentially. The result shows that the negative maxima of MPV are always around the typhoon eyes for all the cases, which means that the sensitive areas are also near them all the time.
