對流層頂

赤道地區的對流層頂比極區更高. 對流層頂是指氣溫不再隨高度而變冷，而且幾乎不含水蒸汽。

定義 大氣分層（不依比例） 赤道地區的對流層頂比極區更高 對流層頂是指氣溫不再隨高度而變冷，而且幾乎不含水蒸汽。

世界氣象組織正式定義為: 對流層與平流層的邊界，氣溫垂直遞減率發生突然變化，其底界的氣溫垂直遞減率小於等於2°C/km，其上2km的平均氣溫垂直遞減率不超過2°C/km.[1]上述定義指出，大氣垂直溫度梯度的不連續性。

[2] 位置 赤道的對流層平均高度17km，而極區的對流層平均高度9km。

[3][4]對流層的氣溫垂直遞減率平均為6.5°C每千米。

[5]:112在平流層，氣溫隨高度增加而增加。

民航班機一般飛行在平流層的底層，以避免雲的影響。
