某地大氣隨高度增加氣溫下降8℃/km,地面氣溫25℃,若此地出現氣溫30℃的乾空氣塊,請問此乾空氣是否會上升?
會
不會
由該空氣的相對濕度決定
由該空氣的絕對濕度決定
Answer explanation
該氣塊的氣溫高於地面的環境氣溫,會上升

某地大氣隨高度增加氣溫下降8℃/km,地面氣溫25℃,若此地出現氣溫25℃的濕空氣塊,請問此濕空氣塊是否會上升?
會
不會
由該空氣的露點高低決定
由該地地面氣壓大小決定
Answer explanation
因該氣塊為飽和氣塊,故上升時的溫度變化為濕絕熱遞減率-6℃/km,比環境溫度降得慢,易上升

測量某山區附近的大氣環境溫度遞減率約為-8℃/km,地面氣溫為20℃,請問1000公尺高的環境溫度約 ? ℃
14
12
10
8
Answer explanation
題意所指為大氣環境溫度的變化,故每公里高降8℃,所以1000公尺高的環境溫度為20-8=12℃
