Weather Terms

You don't have to be a meteorologist to understand the weather. We take the complicated and make it simple.
Blocking High: Strong upper level high pressure which blocks storm systems.
Chinook: A warm or hot and dry wind coming down off of a mountain.
Cirrus: High level feathery clouds.
Condensation: When water vapor (the gas phase of water) changes to a liquid. Heat is released into the air when this occurs.
Convergence: when air is coming together. This can cause clouds or storms, because air at the center of the convergence may be forced to rise.
Cut off low: An upper level low pressure area that is cut off from strong upper level winds to move it. May cause an extended period of cold, rainy days.
Dew: When air at the earth’s surface cools to the point where condensation starts.
Dew point: The temperature where air cools to the point that condensation starts.
Divergence: When air is moving away from an area. Usually associated with fair weather when this occurs near earths surface.
Dryline: A boundary between warm, moist air and hot, dry air, and a location where supercell thunderstorms may occur.
Enhanced Fujita scale: An update to the original tornado intensity scale developed by Dr. Ted Fujita.
Freezing rain: Super cooled rain that freezes on contact with objects.
Isobar: A line that connects points of the same air pressure.
Jet Stream: A strong upper level wind.
Mesoscale Convective Complex: A large somewhat circular cluster of thunderstorm cells that typically occur at night.
Occluded front: When a cold front overtakes a warm front, lifting the warm air off the surface.
Ridge: An area of higher air pressure in the upper atmosphere, typically associated with fair weather.
Subsidence: Sinking air that is associated with fair weather.
Temperature inversion: When air temperature increases with elevation.
Trough: An area of lower air pressure in the upper atmosphere, typically associated with cloud or stormy weather.
