今20p.Mike低氣壓在轉化後逐漸消散淡化不過目前依然看的到它的影子，從雲圖看起來過去一天是乎有向西邊靠近 ...

大大你搞錯了...
轉化後的Mike 是這一隻 = =
北方那團只是一團低緯沒被編號的幅合對流...

今20p.Mike低氣壓在轉化後逐漸消散淡化不過目前依然看的到它的影子，從雲圖看起來過去一天是乎有向西邊靠近一點點。

還活著哦，TS 風力，雖然不是熱帶氣旋。:lol

南半球轉化緯度真的低很多啊，現在還是秋天耶。

早上交由紐西蘭發報，同時認為已轉化並發佈 SW。

大大人家昨天看的時候還沒有轉化才會那樣標的，不過話說回來好可惜喔20p.Mike風暴好短命才過一天就瓦解轉化...哀。

20p.Mike 今天從13p低氣壓強度爆發增強為熱帶風暴噜說實在的滿驚奇的這算是奇蹟它原先都快被風切夾扁成一條線了說，來說說情況人家下面有放大圖今天下午幾度觀察發現它週遭海域環境好轉且它是乎在建立眼牆了目前中心窩附近螺旋相當的深強度仍在繼續增強中。

很少在 JTWC 報文看到「轉為副熱帶」。

63. 190900Z POSITION NEAR 21.3S 159.3W.
    
64. TROPICAL CYCLONE (TC) 20P (MIKE), LOCATED APPROXIMATELY 751 NM EAST-
    
65. SOUTHEASTWARD OF PAGO PAGO, AMERICAN SAMOA, HAS TRACKED SOUTH-
    
66. SOUTHEASTWARD AT 24 KNOTS OVER THE PAST SIX HOURS. ANIMATED INFRARED
    
67. SATELLITE IMAGERY (IR) DEPICTS A CONSOLIDATED LOW LEVEL CIRCULATION
    
68. CENTER (LLCC) WITH PERSISTENT CENTRAL CONVECTION AND BROKEN
    
69. DISPLACED CONVECTION TO THE NORTHWEST AND SOUTHEAST. A 190422Z 37
    
70. GHZ SSMIS MICROWAVE IMAGE DEPICTS A TIGHTLY WRAPPED LLCC THAT IT
    
71. FAIRLY COMPACT. THE INITIAL POSITION IS BASED UPON THE IR ANIMATION
    
72. AND THE MICROWAVE IMAGE WITH FAIR CONFIDENCE. THE INITIAL INTENSITY
    
73. HAS BEEN ASSESSED AT 35 KNOTS BASED ON THE TIGHTLY WRAPPED STRUCTURE
    
74. SEEN IN THE SSMIS IMAGE WHILE DVORAK INTENSITY ESTIMATES WIDELY
    
75. RANGE FROM 25 TO 45 KNOTS WHICH MAY BE DUE TO THE COMPACT NATURE OF
    
76. THE SYSTEM. UPPER LEVEL ANALYSIS REVEALS A FAVORABLE ENVIRONMENT
    
77. WITH STRONG POLEWARD OUTFLOW AND LOW (05 TO 10 KNOTS) VERTICAL WIND
    
78. SHEAR AS THE SYSTEM IS IN PHASE WITH THE NORTHWESTERLY UPPER LEVEL
    
79. FLOW. TC 20P IS CURRENTLY TRACKING QUICKLY ALONG THE WESTERN
    
80. PERIPHERY OF A SUBTROPICAL RIDGE (STR) TO THE EAST. TC MIKE IS
    
81. FORECAST TO CONTINUE POLEWARD AND INTENSIFY IN THE NEAR TERM AS THE
    
82. FAVORABLE UPPER LEVEL CONDITIONS AND WARM SEA SURFACE TEMPERATURES
    
83. PERSIST. NEAR TAU 24, SEA SURFACE TEMPERATURES WILL BECOME
    
84. UNFAVORABLE WHILE DRY AIR AND INCREASING VERTICAL WIND SHEAR WILL
    
85. BEGIN TO IMPACT THE SYSTEM. THESE FACTORS WILL ADDITIONALLY BEGIN TO
    
86. TURN THE SYSTEM INTO A SUBTROPICAL SYSTEM AS THE STRONGER WINDS
    
87. MIGRATE TO THE PERIPHERY AND THE CENTRAL CORE WINDS BECOME WEAK. BY
    
88. TAU 48, TC 20P WILL BECOME EMBEDDED IN THE MID-LATITUDE WESTERLIES
    
89. AND WILL RAPIDLY TRANSITION FROM A SUBTROPICAL SYSTEM INTO A COLD
    
90. CORE, EXTRA-TROPICAL LOW. LIMITED NUMERIC MODEL GUIDANCE IS SLIGHTLY
    
91. SPREAD BUT OVERALL AGREES WITH THE TRACK FORECAST. THERE IS A
    
92. DISTINCT POSSIBILITY THAT THE SYSTEM COULD BEGIN TO TRANSITION
    
93. QUICKER THAN EXPECTED, WHICH COULD LEAD TO WEAKENING SOONER THAN
    
94. FORECAST. DUE TO THIS, THERE IS LOW CONFIDENCE IN THE FORECAST.
    
95. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 190600Z IS 15 FEET. NEXT
    
96. WARNINGS AT 192100Z AND 200900Z. THIS WARNING SUPERSEDES AND
