A baseboard heater typically uses the convection process to suck in
the cold air near the floor, heat up the air, and release the warm air so it can rise up and keep the room warm.

the colder air near the surface.
The principle of the system is to move heavy cold air to prevent stratification, and allow the warmer inversion layer air to replace
the colder air near the ground.

«In winter, the freezing Arctic
air is normally «locked» by strong circumpolar winds several tens of kilometers high in the atmosphere, known as the stratospheric polar vortex, so that the
cold air is confined
near the pole,» said study co-author Marlene Kretschmer from the Potsdam Institute of Climate Impacts Research in Germany, in a press release.
Cold - cloud rain occasionally will refreeze if a layer of subfreezing
air exists
near Earth's surface.
In other words, UHI * is the value of the urban - heat - island effect if wind were not reducing it by replacing warmer
air with
colder; and NSTI * is the effect of the
near - surface temperature inversion if the wind were not mixing up the
air near the ground with the
air a little higher up.
The regional atmospheric circulation over the North Atlantic normally features a high over the Azores and a low

cold air aloft combine with winds that change speed and direction with height.
Hurricanes (Fig. 7) and other tropical cyclones can be thought of as heat engines that take energy in by evaporating warm ocean water, and eject it at a
