97W's structure continued to improve in the past 24 hours and is now a tropical storm. It is named LINGLING by the JMA and is given a number of 18W by JTWC. At 14 HKT, LINGLING was centred 940 km (510 NM) NE of Wake Island.
97W 的結構逐步轉好,並於今天增強為一熱帶風暴,被日本氣象廳命名為玲玲,也被聯合颱風警報中心給予編號 18W。在 14 HKT,玲玲集結在威克島之東北約 940 公里 (510 海里)。

Movement Analysis 路徑分析 |
A subtropical ridge is anchored east of the date line, and situated in the SW periphery of that ridge LINGLING is currently moving northwestwards. There is a weakness between that ridge and the ridge in the NW Pacific, and LINGLING is likely to traverse the weakness to give a standard recurving pattern.
受到在換日線以東的一個副熱帶高壓脊影響,玲玲向西北方向移動。預料玲玲稍後將會通過在該脊與西北太平洋高壓脊間的弱點, 從而向北至東北方向移動。 |
Intensity Analysis 強度分析 |
Current T-number: T2.5/2.5/INT OBS
Situated in the warm ocean, it is expected that LINGLING can strengthen a bit (near t+24) before encountering substantially lower sea surface temperatures and increased vertical wind shear.
現時的 T 號碼: T2.5/2.5/INT OBS
預料玲玲可在溫暖的海水中稍作增強。t+24 之後,隨著玲玲的緯度增加,它將會受較冷的海水及較強的垂直風切變影響而減弱。 |
Effects on Hong Kong 對香港的影響 |
No threat to Hong Kong is expected within the next 72 hours.
玲玲於未來的72小時將不會對香港構成任何影響。 |
