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）

Tropical disturbance 97W formed in the South China Sea just west of Luzon on September 5. Influenced by the subtropical ridge to the north, 97W moved west that day. The convections in 97W's southern semicircle also expanded significantly during the day. The JTWC issued a tropical cyclone formation alert at 8 pm, while both the NMC and HKO upgraded the system into a tropical depression. 97W was expected to move west-northwest to northwest as the ridge would develop to the east of it.

97W strengthened gradually during September 6 while moving west-northwest. The JTWC upgraded it into tropical depression 22W at 2 pm, while the JMA upgraded it into a tropical storm at 8 pm and assigned the name TAPAH. TAPAH's convections were more intense in its southern semicircle, while the northern side was mostly devoid of deep convections due to the presence of drier air. Without gaining much latitude, the storm decelerated early on September 7. The subtropical ridge strengthened to the east and south of TAPAH that day. In the morning, TAPAH started to turn northwest and it began to accelerate towards the north-northwest several hours later.

The NMC upgraded TAPAH into a severe tropical storm at 5 pm September 7 as the storm's structure improved. The HKO, CWA (Taiwan) and JTWC all revised TAPAH's intensity to the equivalent of severe tropical storm strength at 8 pm. Towards midnight September 8, a blob of deep convections developed near TAPAH's core region. That blob developed further into a formative central dense overcast in the next few hours. The JMA and JTWC upgraded TAPAH into a typhoon at 8 am, while the other major official agencies held their estimated wind speeds at the severe tropical storm strength.

TAPAH made landfall near Taishan, Guangdong at 8:50 am September 8. The NMC estimated that TAPAH was packing winds of up to 30 m/s (108 km/h) near its centre at that time. The storm travelled north-northwest turning to northwest inland, and entered Guangxi province that night as a tropical storm. It further weakened into an area of low pressure near Liuzhou and Guilin on September 9.

熱帶擾動 97W 於 9 月 5 日在呂宋以西不遠處的南海上形成。受其北方副熱帶高壓脊的影響，97W 當天向西移動。97W 南半圓的對流當天明顯擴展，聯合颱風警報中心（聯颱）於下午 8 時發出熱帶氣旋形成警報，而中國中央氣象台及香港天文台則將其升格為熱帶低氣壓。由於副高將於 97W 以東發展，當時預料它將向西北偏西至西北移動。

97W 於 9 月 6 日逐漸增強，並向西北偏西移動。聯颱於下午 2 時將其升格為熱帶低氣壓 22W，而日本氣象廳於下午 8 時將 22W 升格為熱帶風暴，命名為塔巴。塔巴南半圓的對流較為猛烈，而受較乾空氣影響，風暴北面深層對流稀疏。塔巴於 7 日早段減速，緯度並未大幅增加。當天副高於塔巴東及南方增強；風暴日間開始向西北移動，數小時後更加速轉向西北偏北。

隨著塔巴的結構改善，中央氣象台於 9 月 7 日下午 5 時將其升格為強烈熱帶風暴。香港天文台、台灣中央氣象署及聯颱均於下午 8 時將塔巴的強度上調至相當於強烈熱帶風暴級別。至 8 日午夜，一團深層對流於塔巴的中心區域發展，並於其後數小時逐漸成為風暴中心密集雲區的雛形。日本氣象廳及聯颱於上午 8 時將塔巴升格為颱風，而其它主要官方氣象台則將其估計風速維持於強烈熱帶風暴級別。

塔巴於 9 月 8 日上午約 8 時 50 分登陸廣東台山一帶，中央氣象台估計塔巴當時近中心風速達每秒 30 米（每小時 108 公里）。風暴於內陸向西北偏北轉西北移動，當晚以熱帶風暴強度進入廣西省。它於 9 月 9 日在柳州及桂林一帶進一步減弱為低壓區。

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

Influenced by the subtropical ridge in southern China, it was mainly fine and extremely hot in Hong Kong prior to the approach of TAPAH. Shortly after noon on September 5, the Observatory said that the low pressure area near Luzon would intensify into a tropical depression that night or the next morning, and that the #1 Standby Signal would be considered. Following the upgrade of TAPAH into a tropical depression that night, the #1 Signal was issued at 10:20 pm when TAPAH was about 690 km southeast of Hong Kong. The Observatory warned that it would be extremely hot on September 6 with air temperatures reaching 35 degrees in urban areas and 38 or even 39 degrees in northern New Territories. It was also suggested that the storm surge associated with TAPAH might result in flooding in low-lying areas in the morning of September 8, as TAPAH's arrival coincided with the spring tide.

At 5 pm September 6, the Observatory suggested that the #3 Strong Wind Signal would be issued between midnight and 3 am September 7. Although TAPAH's circulation was relatively small, it had the potential to skirt around 200 km to the southwest of the territory, and that the need to issue the #8 Gale or Storm Signal would be assessed in the night of September 7.

The #3 Signal was issued at 2:40 am September 7, when TAPAH was situated about 440 km south of Hong Kong. In offshore and elevated locations, easterly winds strengthened somewhat overnight, but they were generally weaker than those typically observed during a #3 Signal. Strong winds were observed at stations such as Cheung Chau, Green Island, Ngong Ping, Tap Mun, Tate's Cairn and Waglan Island in the small hours or early morning of September 7. The rainbands to the north of TAPAH approached Hong Kong and there were some squally showers and thunderstorms that morning. However, as the cloud bands were relatively sparse, the rain did not last long and there were even some sunny intervals during the day.

As TAPAH turned northwest to north-northwest, the Observatory indicated at 3 pm September 7 that the #8 Gale or Storm Signal would be considered between 9 pm and midnight. Dropsonde measurements made by the Government Flying Service confirmed the existence of near-surface wind speeds close to the upper limit of tropical storm strength (more than 85 km/h) near TAPAH's centre. At about 6 pm, the Observatory announced that the #8 Signal would be issued at 9:20 pm, and that it would last at least until 11 am September 8. High-speed ferry services between Hong Kong and Macau, as well as local ferry services, were suspended gradually during the next couple of hours. Meanwhile, local bus operators announced that most services would be suspended by 11:30 pm. As the #8 Signal would still be in force the next morning, the classes of all day schools were also suspended on Monday. Flights to and from Hong Kong were generally unaffected on September 7, but several airlines had to cancel some flights departing on September 8.

Several rainbands arrived at the territory near sunset on September 7. Some locations saw a brief surge in wind speeds; gales were first recorded at Cheung Chau just after 8 pm, and strong force winds were recorded at Kowloon Star Ferry Pier within the Victoria Harbour. As east to southeasterly winds prevailed that night, the Observatory issued the #8 Southeast Gale or Storm Signal; TAPAH had moved to around 250 km south-southwest of Hong Kong at that time.

TAPAH came to within 200 km of Hong Kong near 3 am September 8. Local winds turned south to southeast and strengthened near dawn and in the morning; storm force winds were observed at Cheung Chau, Ngong Ping and Waglan Island, while gales affected more locations including Chek Lap Kok and Sai Kung, two of the eight reference stations. Rain became more persistent as TAPAH's eastern rainbands swept across the territory; the Amber Rainstorm Warning was issued at 4:55 am. TAPAH was closest to Hong Kong at about 8 am, when it passed at a distance of 170 km to the west-southwest. During the morning high tide, the water levels at Tai O, Tai Po Kau and Tsim Bei Tsui were about 0.5 to 0.6 metres above normal, and seawater backflow was reported at Tai O.

At 10 am, the Observatory suggested that the #8 Signal would remain in force at least until 1 pm. One hour later, the time of the signal change was fixed at 1:10 pm. As the rain subsided, the Amber Rainstorm Warning was cancelled at 11:35 am. TAPAH was situated about 210 km west of Hong Kong when the #3 Strong Wind Signal was issued. Following the cancellation of the #8 Signal, public transport services resumed gradually and many employees returned to work in the next few hours. TAPAH's eastern rainbands dissipated gradually as they approached Hong Kong from the south; it was mainly cloudy with a few showers in the afternoon. 85.6 mm of rain was recorded at the Observatory that day, and the rainfall in most parts of Hong Kong exceeded 70 mm.

With the exception of a few offshore and elevated stations, winds in Hong Kong generally weakened to below strong force before sunset. The Observatory replaced the #3 Signal by the #1 Standby Signal at 7:40 pm, when TAPAH was situated about 330 km west-northwest of Hong Kong. The #1 Signal was eventually cancelled at 4:20 am September 9.

The damage in Hong Kong resulting from TAPAH was relatively mild. As of noon September 8, 12 people were injured during the typhoon period and received medical treatment at the Accident and Emergency Department of public hospitals. The government received more than 160 reports of fallen trees and 3 flooding reports as of 1 pm the same day. Arriving from Beijing, flight UO235 operated by HK Express deviated from the runway and hit signage as it touched down at the Hong Kong International Airport near 10:35 am September 8 when the #8 Signal was in force. No injuries were reported. The North Runway was closed for inspection until 12:15 pm, when it was reopened for air traffic.

受華南的副熱帶高壓脊支配，塔巴靠近前香港大致天晴，天氣極端酷熱。9 月 5 日正午後不久，天文台表示位於呂宋的低壓區將會於當晚或翌日早上增強為熱帶低氣壓，並將考慮發出一號戒備信號。隨著天文台當晚將塔巴升格為熱帶低氣壓，一號信號於下午 10 時 20 分發出，當時塔巴位於香港東南約 690 公里。天文台警告 6 日天氣將會極端酷熱，市區氣溫上升至 35 度，新界更可達 38 至 39 度。另外，由於塔巴來臨時正值天文大潮，其風暴潮或於 8 日早上令低窪地區出現水浸。

9 月 6 日下午 5 時，天文台表示將於 7 日午夜至上午 3 時改發三號強風信號。雖然塔巴的環流相對較小，但它有機會於香港西南約 200 公里處掠過，天文台將於 7 日晚上評估是否需要改發八號烈風或暴風信號。

三號信號於 9 月 7 日上午 2 時 40 分發出，當時塔巴位於香港以南約 440 公里。凌晨，離岸及高地的東風稍為增強，但仍較一般三號信號生效時的風勢弱。長洲、青洲、昂坪、塔門、大老山及橫瀾島等地於 7 日凌晨或早上初段錄得強風。塔巴北面的雨帶於早上靠近香港，本地有幾陣狂風驟雨及雷暴。但是，由於雲帶稀疏，降雨持續時間較短，日間甚至短暫時間有陽光。

隨著塔巴轉向西北至西北偏北，天文台於 9 月 7 日下午 3 時提及將考慮於下午 9 時至午夜改發八號烈風或暴風信號。政府飛行服務隊收集的探空數據確認塔巴中心一帶的近海平面風速達熱帶風暴上限強度（超過每小時 85 公里）。下午約 6 時，天文台宣佈會於下午 9 時 20 分改發八號信號，並至少維持至 8 日上午 11 時。其後數小時，連接港澳的高速船及本地渡輪服務陸續暫停，而巴士公司亦宣佈大部份路線的尾班車將於下午 11 時 30 分前開出。由於八號信號於翌日早上仍然生效，所有日校週一停課。7 日來往香港的航班普遍未受影響，但部分航空公司需要取消一些於 8 日離港的航班。

9 月 7 日近日落時份，數道雨帶到達本港，部分地區風速短暫急升。長洲於下午 8 時後首度吹烈風，而位於維港內的九龍天星碼頭亦錄得強風。由於當晚普遍吹東至東南風，天文台發出八號東南烈風或暴風信號，當時塔巴移至香港西南偏南約 250 公里。

塔巴於 9 月 8 日上午約 3 時到達香港 200 公里範圍。本港風向轉為南至東南，破曉至早上風勢增強。長洲、昂坪及橫瀾島吹暴風，而烈風影響範圍較廣，包括 8 個參考站的其中兩個：赤鱲角及西貢。隨著塔巴東面的雨帶橫過本港，雨勢亦漸趨持續，天文台於上午 4 時 55 分發出黃色暴雨警告。塔巴於上午約 8 時最接近香港，於西南偏西約 170 公里處掠過。當天早上漲潮時，大澳、大埔滘及尖鼻咀的水位較正常高約 0.5 至 0.6 米，大澳有海水倒灌報告。

上午 10 時，天文台表示八號信號將至少維持至下午 1 時。一小時後，信號轉換的時間定為下午 1 時 10 分。隨著雨勢緩和，黃色暴雨警告於上午 11 時 35 分取消。三號強風信號發出時，塔巴集結於香港以西約 210 公里。八號信號取消後，公共交通服務逐漸恢復，大部份僱員於其後數小時返回工作崗位。塔巴東面的雨帶由香港以南靠近時逐漸消散，當日下午大致多雲，並有幾陣驟雨。天文台當日錄得 85.6 毫米雨量，而本港大部分地區雨量達 70 毫米。

除部分離岸及高地站外，香港風勢普遍於日落前回落至強風程度以下。天文台於下午 7 時 40 分以一號戒備信號取代三號信號，當時塔巴位於香港西北偏西約 330 公里。一號信號最終亦於 9 月 9 日上午 4 時 20 分取消。

塔巴於香港造成的破壞較為輕微。截至 9 月 8 日正午，12 人於風暴襲港期間受傷並於公立醫院的急症室接受治療。而截至下午 1 時，政府共接獲超過 160 宗塌樹及 3 宗水浸報告。一架由北京抵港的香港快運客機（航班編號 UO235）於 8 日上午約 10 時 35 分降落香港國際機場，當時八號信號正在生效。降落期間，該客機偏離跑道並撞到跑道旁的指示牌。是次事故中無人受傷，而北跑道被暫時封閉以進行檢查，其後於下午 12 時 15 分重開。
