綠色和平根據天文台的數據,為香港不同地區進行估算,找出香港那些地區會最受風暴潮影響,並且製作成地圖供市民參考。到底甚麼是風暴潮呢?

 

根據天文台的資料[1],風暴潮是與熱帶氣旋(即大家一般理解的颱風)相關的低氣壓及大風的共同影響而導致海平面上升的現象。

熱帶氣旋的強風將海水推向岸邊, 並於沿岸地區堆高是海平面上升的主要成因(圖一)。

全球暖化是不爭的事實,隨著氣候危機惡化,類似超強颱風「山竹」所帶來的風暴潮可能在本世紀中變成十年一遇。綠色和平參考香港天文台兩項研究,指出若溫室氣體排放趨勢不變,2051至2060年香港的平均海平面高度或較1986至2005年的平均水平上升近0.6米;而在相若的海平面升幅下,颱風在維多利亞港帶來的十年一遇風暴潮最高水位可達3.8米,接近山竹襲港時的紀錄。

山竹襲港時維港最高潮位達3.88米,其餘位處各區的四個潮汐站甚至錄得更高潮位。綠色和平據此推斷,香港沿海地勢在4米或以下的地方,到本世紀中將較容易受十年一遇、如山竹襲港時的風暴潮影響而出現嚴重水浸的情況。

Climate change is one of the main global environmental changes which the world is experiencing in the 21st century. Urban communities are vulnerable to climate impact for its high density based living arrangements and its heavy reliance on life-line infrastructures for basic survival needs.

A brief review is offered o the scientific background for human-induced climate change. Drawing mostly from the findings of the latest Assessment Report of the United Nations Intergovernmental Panel on Climate Change (IPCC), a survey is made of the observed evolution of climate signals in the past decades, and the projected development of these signals towards the end of the 21st century.
