JTWC:91w - 颱風討論

ABPW10 PGTW 240600

簡譯而已

(1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 6.3N 135.1E
IS NOW LOCATED NEAR 10.0N 133.0E, APPROXIMATELY 330 NM NORTH-
NORTHWEST OF PALAU.

位置移至10.0N 133.0E

ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS
A POORLY-DEFINED, BROAD LOW-LEVEL CIRCULATION CENTER (LLCC) WITH
DISORGANIZED, ISOLATED DEEP CONVECTION FLARING OVER THE LLCC.

LLCC仍然不太成形，有零散的深層對流爆發，但整體組織未完善

A 240022Z ASCAT IMAGE DEPICTS AN ELONGATED CIRCULATION EMBEDDED WITHIN
THE MONSOON TROUGH WITH VIGOROUS 20 TO 25 KNOT WESTERLIES OVER THE
SOUTHERN PERIPHERY OF THE DISTURBANCE AND 10 TO 15 KNOT EASTERLIES
OVER THE NORTHERN SEMI-CIRCLE.

衛星偵得該處有表層長橢圓形渦流，南方吹20-25節西風，北方吹10-15節東風

SURFACE OBSERVATIONS FROM KOROR
INDICATE 10 TO 15 KNOT SUSTAINED WESTERLY WINDS WITH A SLP VALUE
NEAR 1009 MB.

帛琉錄得平均10-15節西風，氣壓為1009 milibar

THE LLCC IS LOCATED WITHIN AN UNFAVORABLE ENVIRONMENT
CHARACTERIZED BY MODERATE TO STRONG (20-30 KNOTS) EASTERLY VERTICAL
WIND SHEAR AND WEAK UPPER-LEVEL DIFFLUENCE.

LLCC附近環境仍然不佳，有20-30節垂直風切變，高層擴散弱

MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1008 MB. BASED ON THE UNFAVORABLE
ENVIRONMENT AND ELONGATED NATURE OF THE LLCC, THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS REMAINS LOW.

估計中心風力為10-15節，氣壓為1009mb
由於LLCC仍然呈長條狀，且環境不佳，故仍然保持為Low

※ 引述《qq00212369 (九天中)》之銘言：
: 我只懂一句: 風切很大
: 剩下交給版上前輩們 !
: JTWC：LOW
: (1) AN AREA OF CONVECTION HAS PERSISTED NEAR 6.3N 135.1E,
: APPROXIMATELY 70 NM SOUTH OF KOROR, PALAU. ANIMATED MULTISPECTRAL
: SATELLITE IMAGERY DEPICTS A BROAD LOW-LEVEL CIRCULATION CENTER THAT
: HAS STARTED TO SLOWLY CONSOLIDATE WITH WEAK FORMATIVE BANDING ALONG
: THE SOUTHERN PERIPHERY AND DISORGANIZED CONVECTION ELSEWHERE.
: SCATTEROMETER DATA FROM 221452Z SHOWS A WEAK, (05-10 KNOTS) BROAD
: CIRCULATION IN THE AREA AND A WESTERLY WIND BURST ALONG THE EQUATOR
: JUST TO THE SOUTHWEST. A 230107Z TRMM MICROWAVE IMAGE SHOWS THE
: CONVECTIVE ORGANIZATION OF THE SYSTEM HAS STARTED TO IMPROVE BUT
: OVERALL REMAINS POOR. UPPER-LEVEL ANALYSIS REVEALS THE LLCC IS
: EMBEDDED IN THE EASTERLY FLOW WHICH IS PROVIDING MODERATE OUTFLOW
: AND MODERATE TO STRONG (20-30 KNOTS) VERTICAL WIND SHEAR. MAXIMUM
: SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA
: LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1008 MB. THE POTENTIAL FOR
: THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
: HOURS IS LOW.
