這大概就是前幾天GFS
一直預測會撞上東澳的系統
原先認為是94P
但94P應該是沒有機會了

甜心

今天的雲圖看起來好像主體結構要瓦解了一樣一大團散開，雲系變很散依然還在澳洲東北部海面附近不過整個很鬆散。

評級Low

AN AREA OF CONVECTION HAS PERSISTED NEAR 9.5S 152.7E,
APPROXIMATELY 380 NM EAST OF PORT MORESBY, PAPUA NEW GUINEA.
ANIMATED MULTISPECTRAL SATELLITE IMAGERY REVEALS A BROAD AREA OF
TURNING WITH BROKEN AND FLARING CONVECTION EMBEDDED WITHIN THE
MONSOON TROUGH. A 042340Z ASCAT PASS SHOWS THE AREA IS HIGHLY
DISORGANIZED AND NO LOW LEVEL CIRCULATION IS PRESENT AT THIS TIME.
UPPER LEVEL ANALYSIS REVEALS AN OVERALL FAVORABLE ENVIRONMENT WITH
LOW TO MODERATE (10 TO 15 KNOTS) VERTICAL WIND SHEAR AND HIGHLY
DIVERGENT OUTFLOW. SEA SURFACE TEMPERATURES IN THE AREA ARE ALSO
FAVORABLE AT 30 DEGREES CELSIUS. DYNAMIC MODEL GUIDANCE, INCLUDING
GFS, ECMWF, AND NAVGEM, ARE AGGRESSIVELY DEVELOPING THIS SYSTEM IN
THE NEXT 48 TO 72 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1007 MB. DUE TO THE OVERALL CURRENT POOR STRUCTURE BUT
FAVORABLE ENVIRONMENT, THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW

今天看起來96p結構問題有改善且已有明顯螺旋性建立應該不用多久就會升格TD了，未來預測路線大至認為後期很可能撲東北澳。

因為目前看來96P最早編號發展較其餘兩者好，所以統一發在這帖

凌晨的風場
LLCC明顯

對流爆發螺旋引現


澳洲地區水氣分布


=========================================
GFS數值串接成GIF檔就可以看好戲了~

98P將在卡灣發展成小鋼砲
96P近三天就可望命名
之後98P與96P將在東澳互旋

99P(編號與否待定)將南移侵襲紐國北島
90P成形後將與98P(96P)再度互旋西侵東澳

反觀南印則是平靜毫無反應~
數值僅供參考~加減看囉XD

升評Medium
THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 12.1S
154.3E, IS NOW LOCATED NEAR 12.6S 153.1E, APPROXIMATELY 287 NM
NORTHEAST OF WILLIS ISLAND, AUSTRALIA. ANIMATED INFRARED SATELLITE
IMAGERY DEPICTS PERSISTENT DEEP CONVECTION ASSOCIATED WITH A SLOWLY-
CONSOLIDATING LOW-LEVEL CIRCULATION CENTER (LLCC). THE ORGANIZATION
HAS IMPROVED OVER THE PAST SIX HOURS, YET REMAINED BROAD AND
ELONGATED AS EVIDENT IN RECENT ASCAT DATA. A 061013Z SSMIS
MICROWAVE IMAGE REVEALS FRAGMENTED CONVECTIVE BANDING WRAPPED INTO
THE CENTER. UPPER-LEVEL ANALYSIS INDICATES THE DISTURBANCE IS
LOCATED IN A MARGINALLY FAVORABLE AREA WITH MODERATE TO STRONG (20
TO 30 KNOTS) VERTICAL WIND SHEAR OFFSET BY GOOD POLEWARD OUTFLOW.
ADDITIONALLY, SEA SURFACE TEMPERATURES (30 DEGREES CELSIUS) IN THE
AREA FAVOR DEVELOPMENT. DYNAMIC MODEL GUIDANCE, INCLUDING GFS,
ECMWF, AND NAVGEM, ARE AGGRESSIVELY DEVELOPING THIS SYSTEM OVER THE
NEXT 48 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15
TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004
MB. DUE TO IMPROVED ORGANIZATION AND FAVORABLE CONDITIONS, THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS UPGRADED TO MEDIUM.
