Storm Formation and Development 氣旋形成和發展

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)

TALIM is the first tropical cyclone this year to necessitate tropical cyclone signals.

A trough of low pressure developed in mid-June and lingered around southern China. The vortex at the western end of the trough deepened on June 16 and more convections started to rotate around the centre near Hainan Island. The HKO upgraded it into a tropical depression at 11 HKT on June 17. Due to the potential threat that the depression could bring to Hong Kong with its rather rare track, the Standby Signal No. 1 was issued at 16:20 HKT when the storm was 480 km southwest of Hong Kong. Meanwhile, a tropical cyclone formation alert was issued by the JTWC in the afternoon of June 17, and the low pressure area was upgraded into tropical depression 06W 12 hours later. At the same time, the JMA upgraded 06W into a tropical storm and named it TALIM. The name was contributed by the Philippines, meaning sharp.

TALIM consolidated quickly with convective banding improving over the next 24 hours. An equatorial cyclone was producing a southwesterly airstream in South China Sea, and TALIM initially moved east slowly under the low-level westerly flow. Numerical weather forecasts were consistent in predicting a gradual turn to the NE as the subtropical ridge would extend to the west and provide northward track component. At that time GUCHOL, another tropical cyclone, was moving north just east of the Luzon Strait, which blocked the extension of the ridge.

泰利為本年首個令香港天文台發出熱帶氣旋警告信號的熱帶氣旋。

一道低壓槽於 6 月中旬形成,並於華南一帶徘徊。在其西端的渦旋於 16 日加深,更多對流開始沿其於海南島一帶的中心旋轉。天文台於 17 日早上 11 時升格該低壓區為熱帶低氣壓。由於預測它將採取比較罕見的路徑,對香港有潛在威脅,天文台在當天下午 4 時 20 分發出一號戒備信號,當時該熱帶低氣壓處於香港西南約 480 公里。另一方面,聯合颱風警報中心於 17 日下午發出熱帶氣旋形成警報,並於 12 小時後將其升格為熱帶低氣壓 06W,而日本氣象廳亦於此時升格 06W 為熱帶風暴,並將其命名為泰利。此名字由菲律賓提供,意思為尖銳。

泰利快速整合,對流旋捲性於隨後 24 小時轉好。一赤道反氣旋當時為南海帶來西南氣流,而泰利初時則沿低層偏西氣流向東緩慢移動。數值預報模式一致預測泰利將因副熱帶高壓脊西伸而轉向東北。在這時,呂宋海峽以東的另一熱帶氣旋古超正阻擋副高的西伸。

Crossing South China Sea 橫過南海

TALIM intensified while moving towards the east. The HKO issued the Strong Wind Signal No. 3 at 22:40 HKT on June 18, the same time when it upgraded TALIM into a severe tropical storm. The Observatory expected that winds would strengthen on Tuesday (June 19) but gales would not be likely, thereby ruling out higher signals. However, it turned out that most stations had registered the strongest winds earlier that day before the issuance of the Strong Wind Signal, and winds were subsiding when the Signal was issued.

As for the general steering environment, GUCHOL moved rapidly towards Japan at around 40 km/h. This allowed the ridge to extend and placed TALIM at its southwestern periphery. As a result, TALIM started to move NE on June 19 and its distance to Hong Kong decreased. Its convections concentrated at its southern periphery. With little precipitation in its northern semicircle, Hong Kong experienced sunny intervals that day. Wind direction backed from east to northeast, and since Hong Kong is sheltered from the north, winds could not pick up at all. Seeing this, the Observatory replaced the Strong Wind Signal by the Standby Signal No. 1 at 10:20 HKT as TALIM moved to 300 km SSE of the territory. Although TALIM continued to edge closer, its threat was clearly smaller than expected. Rainbows could even be easily observed in many places near sunset that day.

TALIM continued to move NE and made its closest approach to Hong Kong early that night (this has been amended to before around 17 HKT in HKO's report). The Standby Signal was cancelled at 20:40 HKT as winds remained weak locally without much chance of strengthening.

泰利於東移期間增強。天文台於 6 月 18 日下午 10 時 40 分改發三號強風信號,並將泰利升格為強烈熱帶風暴。天文台預計風勢將於周二 (19 日) 增強但不大可能達烈風程度,即排除更高信號的可能。但是,最終風勢並沒有增強,很多測風站於三號信號發出前已錄得最強風速,風力於改發信號時呈減弱之勢。

至於整體駛流狀況,由於古超以約每小時 40 公里的高速移向日本,副高得以西伸並使泰利處於其西北面。這令泰利於 19 日開始向東北移動,與香港的距離縮小。泰利的外圍環流集中在其南面,而北面的降雨則非常有限,因此香港當天短暫時間有陽光。風向由偏東逆時針轉至東北,由於香港北面屏障較多,風力完全沒有加大。基於此原因,天文台於當天早上 10 時 20 分發出一號戒備信號,泰利當時於香港東南偏南約 300 公里處。雖然泰利繼續靠近,但其威脅明顯比預期小;當日近日落時分本港多處甚至可見彩虹。

泰利繼續向東北移動,並於當晚早段最接近香港 (於天文台之報告修訂為約下午 5 時)。隨著風速維持於偏低水平且不大可能再次增強,一號信號於下午 8 時 40 分取消

Weakening in Taiwan Strait and East China Sea 於台灣海峽及東海減弱

TALIM accelerated as steering force from the subtropical ridge strengthened. Due to the lower sea temperatures near the Taiwan Strait, TALIM weakened into a tropical storm in the morning of June 20. The storm did not make landfall during its passage across the Strait, but came very close to Taipei near midnight on June 21. It became very difficult to track TALIM's centre as convections were sheared away, and the HKO downgraded it into an area of low pressure at 12 HKT on June 21 when the storm was inside the southern East China Sea.

由於副高所提供的推動力增加,泰利開始加速。台灣海峽附近的海水溫度較低,令泰利於 6 月 20 日早上減弱為熱帶風暴。泰利於橫過台灣海峽時沒有登陸,但於 21 日約午夜時份非常接近台北。另一方面,泰利的對流逐漸被切離,其中心位置變得難以判斷。天文台於 21 日中午 12 時將泰利降格為低壓區,當時它處於東海南部。
