A distinct layer in a body of water where the temperature changes rapidly with depth, separating warmer surface water from...

A bomb cyclone is a large mid-latitude storm that forms when a storm’s central pressure drops (i.e. “bombs out”), resulting...

The process by which a solid changes directly into a gas without first becoming a liquid, such as ice turning into water...

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

Jet streams are strong, fast-flowing air currents in the upper levels of the atmosphere. They form when warm air masses meet...

Precipitation in the form of small balls or lumps of ice that form in thunderstorm updrafts and fall to the ground.

A polar vortex is a circulating mass of air in the atmosphere, typically found in polar regions. This rotating air mass occurs...
