W環寬度雖然有合格. 型態也是130kts 但是很不穩.且很短暫. 環狀底層也不是特別佳.

假設和杜鵑放在一塊.  Ula 我想125kt.就OK了
可能也比不過2014年的Ian










NRL水汽圖登錄向日葵-8衛星之後. 好像水汽就一直就樣?

EOSDIS 去年年底也更新了VIIRS的雲圖

但是和NOAA那個網站的比. 感覺EOSDIS的比較亮白.

K.Richard傳的是NOAA的.

而這個我傳的是EOSDIS

再補一張 2016.01.10 VIIRS 捕捉到的 Ula
拍攝的時機 角度都抓的剛剛好...
剛好處在 Ula 的CDO最飽滿與風眼最清晰的時刻
相當美麗動人

紐西蘭接手發報。

複製代碼

01.10.0130 UTC 的CDO覺得比較均勻一些
可惜Aqua的影像是被切到的 因此擷取向日葵8號的影像 = =
會爆到C4個人也覺得滿驚喜的

更正 圖片的時間是錯的 應改為 2016
