Quick Definitions
Featured Glossary Terms
Petrichor
The earthy scent that rises from dry soil right before rain. It is produced by plant oils and bacterial compounds released when humidity spikes — one of the most reliable physical indicators of an incoming storm.
Wind Chill
The apparent temperature your skin perceives when wind speed strips heat from your body. Wind chill is what makes a 20°F day with strong wind feel like -5°F, and it is the primary measure used in cold-weather school closure decisions.
Ice Dam
A wall of ice that forms at the edge of a roof when melted snow refreezes in the gutters. Ice dams trap melting water under shingles, where it can leak through ceilings and rot the roof deck.
Polar Vortex
A large mass of cold air normally circling the Arctic in the upper atmosphere. When the vortex weakens, frigid Arctic air spills southward into North America and Europe, producing dangerous deep freezes.
Lake-Effect Snow
Heavy, localized snowfall produced when cold air passes over warmer lake water, picking up moisture that falls as snow downwind. Cities like Buffalo, NY can receive several feet of snow from a single lake-effect band while areas just miles away see nothing.
Barometric Pressure
Another name for atmospheric pressure, measured by a barometer. Falling barometric pressure typically signals incoming rain or snow, while rising pressure usually means clear, stable weather is on the way.
Cold Urticaria
A real medical allergy to cold air or cold water in which exposure triggers histamine release, causing hives, swelling, and in rare cases anaphylaxis. Severe cases can react to holding an iced drink or jumping into cold water.
Freeze-Thaw Cycle
The repeated freezing and thawing of trapped water in cracks and seams. Water expands roughly 9% as it freezes, slowly destroying concrete, paint, and outdoor furniture from the inside out.
