Movement Analysis 路徑分析 |
HAIYAN has been slow-moving in the past 24 hours. It is forecast that HAIYAN will turn poleward and then move NE along the northwestern periphery of the subtropical ridge.
海燕過去 24 小時移動緩慢。預料海燕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
HAIYAN is now a warm-core tropical system. It is forecast that HAIYAN 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 72-96 hours.
現時的 T 號碼: T2.5/2.5/INT OBS
海燕仍是一個暖心熱帶系統。受制於較涼的海水 (24 至 26 度) 和頗強的垂直風切變,海燕將不會大幅增強,並會在 72 至 96 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.
海燕於未來的72小時將不會對香港構成任何影響。 |
