JTWC評價Low,並確認本系統為昨日的91W重編

(2) THE AREA OF CONVECTION (INVEST 92W: REPLACES INVEST 91W,
WHICH WAS CLOSED DUE TO TECHNICAL ISSUES) PREVIOUSLY LOCATED NEAR
2.6N 162.1E IS NOW LOCATED NEAR 2.9N 162.0E, APPROXIMATELY 330 NM
SOUTHEAST OF POHNPEI. ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A
060435Z SSMIS 91GHZ PARTIAL MICROWAVE IMAGE SHOW AN ILL-DEFINED LOW
LEVEL CIRCULATION (LLC) WITH FLARING CONVECTION. UPPER LEVEL
ANALYSIS DEPICT FAVORABLE LOW (10-15 KNOT) VERTICAL WIND SHEAR WITH
BROAD POLEWARD OUTFLOW. SEA SURFACE TEMPERATURES (30-31 CELSIUS) IN
THE SURROUNDING WATERS SUPPORT FUTURE DEVELOPMENT. GLOBAL MODELS
INDICATE A NORTH TO NORTHWESTWARD TRAJECTORY WITH GRADUAL
INTENSIFICATION OVER THE NEXT 36-48 HOURS. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 12 TO 18 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1006 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS LOW.

91W終報定位:

91W INVEST 190505 1800 1.8N 160.1E

92W初報定位:

92W INVEST 190506 0000 2.6N 161.5E

從數值預報圖上完全一模一樣的路徑,其實也可佐證昨日編號的91W與今日編號的92W確實就是同一個系統

只是想不明白為啥這隻需要重編,外洋的就先不說了,光是西太,去年底跟今年初很多擾動,對流不停消長,中心不停的換也沒這樣一天內直接重編的

JTWC 01Z評級提升至Medium。

(2) THE AREA OF CONVECTION (INVEST 92W) PREVIOUSLY LOCATED
NEAR 2.9N 162.0E, IS NOW LOCATED NEAR 4.5N 161.2E, APPROXIMATELY 226
NM SOUTHEAST OF POHNPEI. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
SHOWS A LOW LEVEL CIRCULATION (LLC) WITH INTERMITTENT DEEP
CONVECTION OVERHEAD, OBSCURED BY A LARGE CIRRUS SHIELD. A 062305Z
METOP-B ASCAT PASS SHOWS AN ELONGATED CIRCULATION WITH AN AREA OF 15
TO 25 KNOT WINDS TO THE WEST. 92W IS IN A FAVORABLE ENVIRONMENT WITH
MARGINAL (15 TO 20 KNOT) VERTICAL WIND SHEAR OFFSET BY GOOD POLEWARD
OUTFLOW AND WARM (29 TO 30 CELSIUS) SEA SURFACE TEMPERATURE. GLOBAL
MODELS ARE IN GENERAL AGREEMENT THAT 92W WILL TRACK NORTHWESTWARD
AND INTENSIFY TO WARNING STATUS WITHIN 72 HOURS. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1006 MB. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS UPGRADED TO MEDIUM.

JTWC11/0600Z降評Low，原先剛編擾時系集模式皆有反應的GFS也不再支持發展

(1) THE AREA OF CONVECTION (INVEST 92W) PREVIOUSLY LOCATED
NEAR 6.1N 158.3E, IS NOW LOCATED NEAR 6.7N 158.5E, APPROXIMATELY 30
NM SOUTHEAST OF POHNPEI.  ANIMATED MULTISPECTRAL SATELLITE IMAGERY
DEPICTS A LARGE MASS OF ROTATING CONVECTION SHEARED TO THE NORTH OF A
BROAD LOW LEVEL CIRCULATION (LLC). A 102322Z ASCAT PASS SHOWS A WEAK,
ELONGATED LLC AROUND THE ISLAND OF POHNPEI WITH A LINE  OF TROUGHING
EXTENDING NORTHEAST BELOW THE STRONGEST CONVECTION. UPPER LEVEL
ANALYSIS SHOWS THE SYSTEM IS BELOW A POINT SOURCE, ENABLING STRONG
EQUATORWARD OUTFLOW ALOFT WHILE POLEWARD OUTFLOW IS INHIBITED BY THE
SUBTROPICAL RIDGE. THE AFOREMENTIONED SHEAR IS IN THE MODERATE-HIGH
RANGE (15-25KTS) BUT DECREASES TO THE NORTH. SEA SURFACE TEMPERATURES
REMAIN FAVORABLY WARM (29-31C) IN THIS REGION OF THE EQUATORIAL
PACIFIC. GLOBAL MODELS ARE IN GENERAL AGREEMENT ON A NORTHWESTWARD
TRACK TOWARDS THE MARIANAS, WITH MOST BACKING OFF FROM PREVIOUS
ESTIMATES OF DEVELOPMENT POTENTIAL. THERE IS A GREATER DEGREE OF
UNCERTAINTY IN THE LATE TAU, AS THE UKMO SHOWS THE SYSTEM RECURVING
EARLY, PRIOR TO REACHING THE MARIANAS ISLANDS, AND THE GFS AND ECMWF
DISSIPATING 92W ENTIRELY AS IT IS ABSORBED INTO A COLD FRONT TO THE
NORTH. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20
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 DOWNGRADED TO LOW.

JTWC於12/1400Z取消評級

(1) THE AREA OF CONVECTION (INVEST 92W) PREVIOUSLY LOCATED
NEAR 9.1N 153.7E, HAS DISSIPATED AND IS NO LONGER SUSPECT FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 24 HOURS.
