對流爆發中 看習慣逆時針旋轉的颱風後再看南半球會很不習慣XD |

衛星雲圖分析公報。這個我自己其實有幾項看不太懂XD 大概知道A-G在講什麼，但F、H、I不清楚 A是系統等級和編號，以及相對方位、B是時間、C是緯度、D是經度 E是衛星和頻道、F是德法(但除了第一項是最終數值以外其他都不清楚) G是分析所使用的衛星雲圖的種類 TPPS11 PGTW 170946 |

對流區域(追蹤編號90P)初始位置位於接近西經148.5度、南緯16.3度，當前位於接近西經145.7度、南緯19.9度，即在巴比提東南東方416.7公里之海面上。 THE AREA OF CONVECTION (INVEST 90P) PREVIOUSLY LOCATED NEAR 16.3S 148.5W IS NOW LOCATED NEAR 19.9S 145.7W, APPROXIMATELY 225NM EAST-SOUTHEAST OF PAPEETE, TAHITI, FRENCH POLYNESIA. 多色階動態衛星雲圖顯示系統之東北象限有一顯著低層環流中心，該低層環流中心部分外露，並伴隨有雜亂深層對流雲系。祖魯時間17日3時55分之SSMIS 9GHz掃描顯示，有破碎雲帶正於低層環流中心東半側上空進行整合。 ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A DEFINED, PARTIALLY-EXPOSED LOW-LEVEL CIRCULATION CENTER (LLCC) WITH DISORGANIZED DEEP CONVECTION OVER THE EAST AND NORTH QUADRANTS. A 170355Z SSMIS 91GHZ COMPOSITE IMAGE SHOWS SHALLOW BANDING WRAPPING INTO AN ORGANIZED LLCC WITH FRAGMENTED BANDING OVER THE EASTERN SEMI-CIRCLE. 系統當前正處於一高層槽之前緣，強烈高空分流令對流得以持續；同時系統正面臨強烈偏弱(20至40節)之垂直風切影響。 THIS SYSTEM IS LOCATED ALONG THE LEADING EDGE OF AN UPPER-LEVEL TROUGH WITH STRONG DIFFLUENCE FUELING THE PERSISTENT CONVECTION. THE SYSTEM IS LOCATED UNDER STRONG VERTICAL WIND SHEAR (20-40 KNOTS). 全球模式預報，隨著此系統持續隨高層槽導引向南移動，在未來1至2日內此系統將完全轉化為副熱帶系統。預報之最大持續風速為20至25節、最低氣壓為接近1002百帕。 THE GLOBAL MODELS INDICATE A SOUTHWARD TRACK AND INTENSIFICATION TREND AS THE SYSTEM MOVES UNDER THE UPPER-LEVEL TROUGH AND TRANSITIONS TO A FULLY SUBTROPICAL CYCLONE WITHIN THE NEXT ONE TO TWO DAYS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1002 MB. 此系統於未來24小時內發展為一顯著熱帶氣旋之可能性評級維持低。 THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS LOW. |

本帖最後由 kibishi0515 於 2017-2-16 15:41 編輯 一對流區域(追蹤編號90P)，初始位置*位於接近西經148.6度、南緯13.4度；當前位於接近西經148.5度、南緯16.3度，即在法屬玻里尼西亞大溪地巴比提東北東方194.5公里之海面上。 THE AREA OF CONVECTION (INVEST 90P) PREVIOUSLY LOCATED NEAR 13.4S 148.6W IS NOW LOCATED NEAR 16.3S 148.5W, APPROXIMATELY 105NM NORTH-NORTHEAST OF PAPEETE, TAHITI, FRENCH POLYNESIA. 多色階動態衛星雲圖顯示其低層環流中心處於外露狀態，並有深對流雲系殘餘存在於其北側外圍。系統當前位於一高層槽之邊緣地帶，強烈高空分流令系統對流得以持續。 祖魯時間16日2時14分之SSMIS 37GHz掃描合成顯示有整合失敗之雲系存在於系統北半部上空；系統之南半部未有進行任何中心建構或雲系整合的跡象。 ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A BROAD LOW-LEVEL CIRCULATION CENTER (LLCC) WITH DISORGANIZED DEEP CONVECTION FLARING ALONG THE NORTHERN PERIPHERY. THIS SYSTEM IS LOCATED ALONG THE LEADING EDGE OF AN UPPER-LEVEL TROUGH WITH STRONG DIFFLUENCE FUELING THE PERSISTENT CONVECTION. A 160214Z SSMIS 37GHZ COMPOSITE IMAGE SHOWS FRAGMENTED BANDING OVER THE NORTHERN SEMI-CIRCLE OF THE SYSTEM WITH NO EVIDENCE OF A DEFINED CENTER OR ANY BANDING OVER THE SOUTHERN SEMI-CIRCLE. 海面觀測測得1002至1003百帕之最低氣壓值，但該區域之風力相當柔和；SSMIS風場掃描顯示其北側之對流雲帶具有更強的風力。 SURFACE OBSERVATIONS FROM THE AREA INDICATE SLP VALUES NEAR 1002 TO 1003MB BUT GENERALLY LIGHT WINDS. HOWEVER, THE SSMIS WIND PRODUCT DID SHOW STRONGER WINDS ASSOCIATED WITH THE CONVECTIVE BANDS TO THE NORTH. 全球模式預報，隨著此系統持續隨高層槽導引向南移動，在未來2至3日內此系統將完全轉化為副熱帶系統。預報之最大持續風速為15至20節、最低氣壓為接近1002百帕。 THE GLOBAL MODELS INDICATE A SOUTHWARD TRACK AND INTENSIFICATION TREND AS THE SYSTEM MOVES UNDER THE UPPER-LEVEL TROUGH AND TRANSITIONS TO A FULLY SUBTROPICAL CYCLONE WITHIN THE NEXT TWO TO THREE DAYS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1002 MB. 此系統於未來24小時內發展為一顯著熱帶氣旋之可能性評級維持低。 THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS LOW. *Previously Location在JTWC的用語中所指的是JTWC第一次對系統發報時系統所在的位置，故譯為初始位置。 |
