Storm Summary 氣旋摘要

除非特別註明,下文時間均為香港標準時間 (協調世界時加 8 小時)

Tropical depression 19W developed near Pohnpei on October 2, originating as a tropical wave. It intensified into a tropical storm on October 3, and was named VONGFONG that night. VONGFONG moved WNW steadily along the southwestern periphery of a subtropical ridge. The storm was expected to move across very warm seas as tropical cyclone activity had been rather limited in that region, and hence it was generally believed that VONGFONG could reach significant strength.

VONGFONG intensified into a typhoon on October 5 when an eye appeared to be forming. It approached Guam later that day, and became slightly disorganized due to poorer upper-level environment. Nevertheless, as conditions improved again on October 7, VONGFONG deepened rapidly as it turned westward. A clear eye became visible on satellite images that morning; the JTWC upgraded VONGFONG into a category 3 typhoon at 8 am, and further into category 4 six hours later.

VONGFONG continued to intensify that night, as seen from the deepening of its central dense overcast. By 8 pm, satellite images revealed a ring of cloud top temperatures below -80 degrees within the eyewall. The storm reached its peak intensity during the first half of October 8, with an estimated strength of 155 knots (287 km/h) by the JTWC. This is the intensity corresponding to a Dvorak number of T7.5, and with this VONGFONG became the most intense tropical cyclone so far this year.

As VONGFONG reached the western edge of the subtropical ridge, it decelerated and poised for a poleward turn. Its eyewall warmed in the morning of October 8 and the intensity estimate was lowered to 145 knots (268 km/h), still above the lower limit for category 5. The HKO, however, believed that VONGFONG reached its peak strength that afternoon with an estimated intensity of 240 km/h (130 knots), which surpassed the 230 km/h reached by HALONG in August.

VONGFONG turned north on October 9. Its wind radii enlarged significantly at the same time, which enhanced the northeast monsoon prevailing near Taiwan. Rough seas stranded the Taiwanese research vessel Ocean Researcher V on October 10 near Penghu, resulting in 2 deaths as the vessel subsequently sank. VONGFONG could be seen exhibiting a double eyewall feature on October 9 and 10 as it weakened gradually. The subtropical ridge strengthened slightly at this time which caused VONGFONG to move NNW on October 11, impacting Okinawa as a minimal typhoon.

The subtropical ridge reorientated and placed VONGFONG at its northwestern periphery. As a result, the storm turned NE on October 12, making landfall near Kagoshima on October 13. It accelerated as it became embedded within the westerlies and crossed Japan along its major axis. It turned extratropical as it reached Tokyo and emerged into the Pacific Ocean again.

熱帶低氣壓 19W 於 10 月 2 日在波納佩島附近發展,初時為一東風波。它於 3 日增強為熱帶風暴,於當晚被命名為黃蜂。黃蜂沿副熱帶高壓脊西南部穩定向西北偏西移動。由於該區最近缺乏熱帶氣旋活動,黃蜂將經過非常溫暖的海域,因此一般預料黃蜂能增強至較可觀的強度。

黃蜂的風眼於 5 日開始發展,被升格為颱風。它於當天較後時間靠近關島,因高層大氣環境較差而變得略為鬆散。雖然如此,隨著大氣環境於 7 日改善,黃蜂急劇增強並向西移。當天早上風眼變得清晰可見,聯合颱風警報中心於早上 8 時將黃蜂升格為三級颱風,並於六小時後進一步升格為四級颱風。

黃蜂於當晚繼續增強,中心密集雲區變得更為深厚,下午 8 時之衛星雲圖可見眼牆中有一環狀區域,其雲頂溫度低至 -80 度以下。風暴於 8 日早段到達巔峰強度,聯合颱風警報中心估計為 155 節 (每小時 287 公里),此為德沃夏克分析法中 T 指數 7.5 之對應強度,黃蜂亦成為本年至此最猛烈的熱帶氣旋。

隨著黃蜂到達副高西沿,它開始減速並呈北轉之勢。它的眼牆於 8 日早上開始變暖,強度跌至仍屬五級超級颱風的 145 節 (每小時 268 公里)。另一邊廂,香港天文台認為黃蜂當天下午到達其巔峰強度,風速為每小時 240 公里 (130 節),超越 8 月時夏浪所達的每小時 230 公里。

黃蜂於 9 日轉向北移,而其風圈開始明顯擴大,令台灣一帶的東北季候風加強。台灣研究船「海研五號」於 10 日因大浪擱淺沉沒,造成兩位研究員死亡。黃蜂於 9 及 10 日出現雙重眼壁結構,風暴逐漸減弱。副高於此時稍為增強,令黃蜂於 11 日向西北偏北移動,以颱風下限強度掠過沖繩島。

副高的型態其後有所改變,令黃蜂處於其西北沿,因此黃蜂於 12 日轉向東北移動,並於 13 日在鹿兒島一帶登陸。黃蜂隨後併入西風帶並加速,沿日本主軸線推進,並於靠近東京前後轉化為溫帶氣旋,繼而重新進入太平洋。
