Conduction is the transfer of heat or electricity through a material without the material itself moving. This occurs when...

A condition in which the stratification of the atmosphere depends on both air temperature and pressure, and where surfaces...

A cold core low is a low-pressure system where the coldest temperatures are found near the center. These systems are often...

A line of severe thunderstorms that can form along or ahead of a cold front, often producing strong winds and heavy rain.

The lowest level of a given cloud or cloud layer in the atmosphere, relative to the observer's position above the ground.
