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 disturbance near Guam intensified into tropical depression 16W on September 9. 16W was under the influence of the Pacific subtropical ridge and was moving west-northwest in its southern periphery. It developed steadily in warm seas and the JMA upgraded it into a tropical storm at 2 pm September 10, naming it MERANTI. Its track speed increased on September 11 as it intensified into a typhoon.

As MERANTI moved into a pool of warmer waters, it underwent explosive deepening on September 12. The JTWC's assessment was adjusted upwards from 115 knots (213 km/h) at 8 am that day to 155 knots (287 km/h) 12 hours later. MERANTI developed a deep central dense overcast that night; its intensity was revised to 160 knots (296 km/h) on September 13 and further to 165 knots (306 km/h) early September 14 as the storm crossed the Luzon Strait. At the same time, the intensity assessments by the HKO, JMA, the NMC of China and CWB of Taiwan were 130 knots (240 km/h), 120 knots (222 km/h), 68 m/s (245 km/h) and 58 m/s (209 km/h) respectively. MERANTI's eye passed through the island of Itbayat at around 1:30 am; hourly wind and sea level pressure measurements of 180 km/h and 934 hPa were recorded at 1 am.

MERANTI moved at a more northerly direction in the morning of September 14, passing just south of Hengchun. The storm started to weaken due to its proximity to landmass, but remained a significant typhoon. As the subtropical ridge retreated and the storm reached its southwestern periphery, it turned north-northwest and made landfall near Xiamen early on September 15. The storm weakened more rapidly after landfall and became an area of low pressure on September 16.

於關島附近的一個熱帶擾動於 9 月 9 日增強為熱帶低氣壓 16W。16W 當時處於太平洋副熱帶高壓脊南沿,受其影響向西北偏西移動。它於溫暖海域中穩定發展,日本氣象廳於 10 日下午 2 時將其升格為熱帶風暴,並命名為莫蘭蒂。莫蘭蒂於 11 日增強為颱風,移速有所增加。

隨著莫蘭蒂進入更暖海域,它於 12 日出現爆發性增強。聯合颱風警報中心對其估算強度由當天上午 8 時的 115 節 (每小時 213 公里) 上調至 12 小時後的 155 節 (每小時 287 公里)。莫蘭蒂當晚發展出一深厚中心密集雲區,於 13 日進一步增強至 160 節 (每小時 296 公里),至 14 日凌晨更以 165 節 (每小時 306 公里) 強度橫過呂宋海峽。與此同時,香港天文台、日本氣象廳、中國氣象台及台灣中央氣象局估計其強度分別為 130 節 (每小時 240 公里)、120 節 (每小時 222 公里)、每秒 68 米 (每小時 245 公里) 及 每秒 58 米 (每小時 209 公里)。莫蘭蒂的風眼於上午 1 時 30 分左右橫過伊巴雅特島,當地於上午 1 時錄得整點風速及海平面氣壓分別為每小時 180 公里及 934 百帕斯卡。

莫蘭蒂於 14 日早上採取較北方向移動,掠過恆春以南海域。由於風暴靠近陸地,它開始減弱,但仍為一較強勁颱風。隨著副熱帶高壓脊東退,風暴處於其西南沿,它轉向西北偏北移動,於 15 日早段登陸廈門。登陸後,風暴的減弱速度加快,最終於 16 日減弱為一低壓區。

Weather in Hong Kong During Approach 風暴影響時香港天氣狀況

香港天文台相關天氣報告連結14/9 15/9

Due to MERANTI's subsidence, it was very hot and hazy in Hong Kong on September 14. The #1 Standby Signal was issued at 10:10 am that day as the storm entered the South China Sea as a super typhoon, when it was 660 km east of Hong Kong. As the storm turned northwest earlier than expected, it maintained a considerable distance from the territory and there was no significant impact.

The #1 Standby Signal was cancelled at 4:20 am September 15, after MERANTI had made landfall in Fujian. However, the storm turned northwest briefly after landfall and was actually closest to Hong Kong later at 11 am, at a distance of 460 km.

受莫蘭蒂相關的下沉氣流影響,香港於 9 月 14 日天氣酷熱,並有煙霞。莫蘭蒂當天以超級颱風強度進入南海,香港天文台於上午 10 時 10 分發出一號戒備信號,當時風暴集結於香港以東約 660 公里。由於莫蘭蒂比預期較早轉向西北,它一直與香港保持一段距離,並未有造成明顯影響。

莫蘭蒂登陸後,天文台於 15 日上午 4 時 20 分取消一號戒備信號,但風暴其後短暫向西北移動,至上午 11 時才最為接近香港,當時距離為 460 公里。
