Around sunrise. This is when the surface has had all night to cool off, radiating heat back into the atmosphere. When there are no clouds to trap that heat, the heat from the surface is free to leave the earth as quickly as the surface temperature permits. On these nights, the temperature at the surface is able to cool more quickly than the atmosphere directly above it, thereby creating an inversion in the typical atmospheric profile. Once the sun comes up and begins heating the surface, however, that inversion will disappear as the surface once again heats up more quickly than the air above it.
Temperature inversion
Yes, the upper stratosphere is colder than the lower stratosphere. This is because the stratosphere is heated from below by the Earth's surface, so as you move higher in the atmosphere, the temperature decreases. The temperature inversion between the lower and upper stratosphere is due to the absorption of solar radiation by ozone in the upper stratosphere.
Black dwarfs have the lowest surface temperature.
yes. depends on the temperature of the liquid
Temperature Inversion
A temperature inversion.
A temperature inversion is when the temperature rises with height in the troposphere rather than decreasing, as it typically does. This is most common at the surface, particularly at higher latitudes on cold mornings. It isn't dangerous to my knowledge, except perhaps specific interests in aviation for example.
When warm air raises above cooler keeping it at the surface.
is a temperature inversion with freezing rain at a higher altitude.

One thing that can happen is that you get freezing rain, which is precipitation that falls as a liquid (through warmer air aloft) and then freezes on the ground or near the ground because the inversion has caused colder air to accumulate at the surface. This can present a dangerous situation for driving.
