Storm Development Overview 風暴發展概覽 |
Unless otherwise stated, all times below are in Hong Kong Standard Time (UTC+8)
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)
A tropical depression formed west of Guam on September 22-23. The JTWC assigned the storm number 20W to this system in the morning of September 23; at the same time, the JMA upgraded the system into a tropical storm and named it MEGI. MEGI drifted north-northwest prior to its formation but was expected to move west-northwest steadily towards Taiwan due to a broad subtropical ridge in northwest Pacific firmly established south of Japan.
MEGI's convections were initially concentrated in its eastern and southern sides. However, with decent sea temperatures and low vertical wind shear, MEGI developed gradually and intensified into a severe tropical storm on September 24. The storm further intensified into a typhoon on September 25 and continued to move west-northwest to the east of the Luzon Strait. It developed a rather large banding eye prior to landfall on September 26-27, before deflecting slightly equatorward and making landfall near Hualien in the afternoon of September 27. It reached category 3 (severe typhoon) strength at landfall.
MEGI weakened quickly upon landfall; it briefly tracked west-southwest due to Taiwan's terrain but turned west-northwest as it crossed the Taiwan Strait on September 28. The storm made its second and final landfall near Quanzhou, Fujian as a marginal typhoon, after which it moved west inland. A weakness in the subtropical ridge caused MEGI to stagnate in Jiangxi, and it turned north before dissipating gradually on September 29.
一個熱帶低氣壓於 9 月 22 至 23 日在關島以西形成。聯合颱風警報中心於 9 月 23日早上對其給予風暴編號 20W,而日本氣象廳則於同一時間將其升格為熱帶風暴,並命名為鮎魚。鮎魚形成之前向西北偏北移動,但受日本以南的廣闊副熱帶高壓脊影響,預料鮎魚向西北偏西移動,大致趨向台灣。
最初鮎魚的對流集中在風暴東及南方。但是,受惠於較高海溫及低垂直風切變,鮎魚逐漸發展並於 24 日增強為強烈熱帶風暴,繼而於 25 日增強為颱風。風暴於呂宋海峽以東繼續向西北偏西移動。鮎魚於 26 至 27 日發展出一較大雲捲風眼,於 27 日下午略為北偏後於花蓮一帶登陸,登陸時達三級颱風 (強颱風) 強度。
登陸後鮎魚快速減弱;受台灣地形影響,鮎魚短暫向西南偏西移動。風暴於 28 日橫過台灣海峽,並回復其西北偏西之路徑。鮎魚於福建泉州一帶作最後一次登陸,當時強度為颱風下限。由於副熱帶高壓脊出現一弱點,鮎魚於江西停滯,隨後轉向偏北移動,並於 29 日逐漸消散。

Subsidence associated with MEGI affected Hong Kong on September 26 and 27. North to northwesterly winds prevailed and resulted in hazy weather on both days. It was very hot on September 27; the maximum air temperature recorded at the HK Observatory was 34.9 degrees, and many places registered temperatures in excess of 35 or even 36 degrees.
As MEGI came closer, northwesterly winds strengthened and the Observatory issued the #1 Standby Signal at 8:40 am September 28, when the storm was around 510 km from the territory (adjusted to 490 km in the TC report). Strong winds were recorded briefly in several locations when the Standby Signal was in force, including Cheung Chau and Lau Fau Shan, two of the eight reference stations. However, winds subsided later that evening as MEGI weakened inland. The Standby Signal was cancelled at 11:10 pm the same day when MEGI had weakened into a tropical depression and was situated around 420 km from Hong Kong. Precipitation was insignificant throughout.
鮎魚相關的下沉氣流於 9 月 26 及 27 日影響香港,本港普遍吹北至西北風,並有煙霞。27 日天氣酷熱,天文台錄得最高氣溫 34.9 度,多處更錄得 35 甚至 36 度以上的高溫。
隨著鮎魚靠近,西北風有所增強,天文台於 28 日上午 8 時 40 分發出一號戒備信號,當時鮎魚距離香港約 510 公里 (熱帶氣旋報告中修訂為 490 公里)。信號生效期間部分地區曾短暫錄得強風,包括八個參考測風站的其中兩個:長洲及流浮山。由於鮎魚於內陸減弱,本港風勢於晚間放緩。天文台於同日下午 11 時 10 分取消一號戒備信號,當時鮎魚已減弱為熱帶低氣壓,並距離香港約 420 公里。鮎魚靠近期間本港沒有明顯降雨。
