逆溫即溫度逆增,其本上有兩種清況:
1)輻射逆增:
指在無雲和風的晚上,地表輻射大量散失,使地表和接近地面的空氣急速受冷,當低層空氣的溫度下降較上層急速時,溫度隨高度上升。
2)地面逆增:
指冷空氣隨山坡下降,使山谷中的溫度比上層空氣較冷,形成溫度逆增。

而懸浮粒子只是凝結核的其中一種,其他還可以有冰晶、二氧化硫、鹽、碘化銀等,都是凝結核。

Temperature inversion:

Normally, the higher the altitude, the lower air temperature, and vice verse. Because solar energy is converted to sensible heat at the ground, which in turn warms the air at the surface.

Temperature inversion occurs when a layer of warm air aloft acts as a lid above a layer of cold air. The colder, denser air close to the ground does not readily circulate (mix). Pollutants such as carbon monoxide and particle pollution and ozone-producing hydrocarbons are “trapped” in the cold air by the lid. The quantity of pollution tends to increase until the lid is destroyed by heating or by wind.

There are two types of temperature inversions: surface inversions that occur near the Earth's surface, and aloft inversions that occur above the ground. Surface inversions are the most important in the study of air quality.
