JTWC 的 Long 女士分析為「副熱帶擾動」。:o

JTWC評級LOW
AN AREA OF CONVECTION HAS PERSISTED NEAR 33.5N 154.0E,
APPROXIMATELY 775 NM EAST OF TOKYO, JAPAN. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY DEPICTS AN ELONGATED LOW LEVEL CIRCULATION CENTER
HAS BEEN QUICKLY PROGRESSING TO THE EAST-NORTHEAST WITH AN UPPER
LEVEL ANTICYCLONE LOCATED OVER THE SYSTEM. PERSISTENT DEEP CONVECTION
HAS BEEN LOCATED ON THE SOUTHEASTERN PERIPHERY OF THE AREA. SEA
SURFACE TEMPERATURES ARE IN A MARGINALLY FAVORABLE ENVIRONMENT. A
RECENT 251107Z ASCAT PASS SHOWED SOME 15 TO 20 KNOT WINDS ALONG THE
SOUTHEASTERN QUADRANT. MODEL GUIDANCE INDICATES A WEAKENING OF THE
CIRCULATION AS IT BEGINS TO MOVE MORE NORTHWARD. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1010 MB. BASED ON THE ELONGATED
SURFACE LOW TRACKING QUICKLY INTO A LESS FAVORABLE ENVIRONMENT, AND
A LACK OF MODEL DEVELOPMENT, THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.

這隻擾動低壓寶寶目前的緯度好像有點太高了,未來如果真的依照日本氣象廳的預測朝東北移動的化那真的不怎麼好發展說。  發表於 2014-8-25 18:38

現在看起來是高偉環境比低緯來的好些!  發表於 2014-8-25 10:08
緯度太高 應該沒機會了...  發表於 2014-8-25 09:54
比玉兔還好…  發表於 2014-8-25 09:44
這隻應該不會再成長了,緯度太高.  發表於 2014-8-25 09:02
