Movement Analysis 路徑分析 |
Steered by the westerlies, PODUL has been moving at a high speed in the past 24 hours. It is expected that PODUL will move NE along the NW periphery of the subtropical ridge.
受西風帶影響,楊柳在過去 24 小時以高速向東北移動。預料楊柳將在餘下時間沿副熱帶高壓脊西北部向東北移動。 |
Intensity Analysis 強度分析 |
Current T-number: T2.5/2.5/INT OBS
It is forecast that PODUL will not intensify much further as a result of cool sea surface temperatures (24-26 degrees) and increasing vertical wind shear. Extratropical transition is expected to complete in 36 hours.
現時的 T 號碼: T2.5/2.5/INT OBS
受制於較涼的海水 (24 至 26 度) 和頗強的垂直風切變,楊柳將不會大幅增強,並會在 36 小時內轉化為溫帶氣旋。 |
Effects on Hong Kong 對香港的影響 |
No threat to Hong Kong is expected within the next 72 hours.
楊柳於未來的72小時將不會對香港構成任何影響。 |
