鋒面逆溫 Temperature Inversion - by Front

The topic discussed today is temperature inversion in the windward side. When warm and cold air masses meet, the lighter warm air rises above the cold air. This phenomenon, known as temperature inversion, causes temperatures to increase with height in the vicinity of the windward side. Temperature inversions typically occur when warm air passes through. The lower part of the inversion layer acts as the lower boundary of the windward side, while the upper part acts as the upper boundary. The inversion layer strongly inhibits the dispersion of air pollutants, leading to the accumulation of aerosol particles and water vapor below the inversion layer. As a result, smog can appear in the lower atmosphere. 今日講嘅主題係風面逆溫 當冷暖氣團相遇嘅時候 較輕嘅暖空氣會爬到冷空氣嘅上方 喺風面嘅附近會出現氣溫隨住高度增加而提升呢個現象 呢個稱之為風面逆溫 風面逆溫通常發生喺暖風過境嘅時候 逆溫層嘅底部相當於風面嘅下界面 逆溫層嘅上部相當於風面嘅上界面 由於逆溫層對空氣最流量強烈嘅抑制作用 而不利於大氣污染物嘅擴散 大量嘅氣溶膠粒同水氣會積聚喺逆溫層嘅下方 因此極近地層嘅地方會出現煙霧
