大概翻一下，有錯請指正，括弧就是不確定 : ---------------------------------------------------------------------- : Sepat provides another stunning example of the quandary facing the TC : warning community. : 1. Double eyewalls create a secondary wind max, potentially at a much : larger radius than the original single eyewall. 雙眼牆颱風有第二個最大風速（wind max），其半徑範圍可能比原本單眼牆時大 : 2. If the inner eye collapses, the radius of max winds makes a step jump : to a much larger radius. 內眼牆若崩潰，最大風速（max winds）半徑範圍會跳躍式上升 : 3. Even if the inner eye does not collapse, it typically becomes much : weaker. 即使內眼牆沒崩潰，也會變弱 : In both scenarios, the secondary eyewall and its associated high winds : present a radically expanded wind field for those in its path during : landfall. Coastal warnings, preparations and the expectations of all : folks in the landfall region must realize that max winds will NOT be : contained within the "typical" small inner core that encompasses 10s of : km, but now can be multiple times larger in size. 不管內眼牆崩不崩潰，外眼牆在登陸時會有強風及大範圍（跟單眼牆比），而且要小心，跟一般颱風的十幾公里眼牆比幾來，大了好幾倍 : Hurricane Katrina is the classic case, since it was in double eyewall : mode at landfall and did NOT collapse the inner eye AND shrink the 2nd : eyewall back to replace the inner eye prior to landfall. 卡催那就是典型例子，她在登陸時仍是雙眼牆，內眼牆並沒有崩潰被置換至第二眼牆 : Thus, not only are we faced with the usual landfall timing and max : intensity dilemmas, our need has now advanced to "what eyewall cycle : stage will the storm be in at landfall"? This presents fascinating : opportunities for research efforts on multiple fronts. 因此，現在不是只有看登陸時間和最大強度了，現在還要進步到看『颱風登陸時眼牆狀態』：這是個值得研究的迷人課題之一 : Best wishes to our friends in Taiwan. 祝福在台灣的朋友 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 59.117.217.226
