Temperature Inversion

This phenomenon is observed in lots of places but this was the first time I realized that it actually had name associated with it. Temperature Inversion is the condition where the temperature increases with altitude, instead of decreasing. Due to this, it is warmer to stay on the hills rather than the valleys.
One of the reasons that temperature inversion occurs is because warm air gets sandwiched between the cold air at very high altitudes and the air that is in close proximity to the cold surface. Thus a profile of temperature against altitude would show that the slope of the curve inverting as it goes from cold to warm to cold. The most common observation of temperature inversion is the steam rising from houses tends to form a horizontal layer of smog instead of rising all the way up.
