These 3 conditions are the recipe for a thunderstorm.
What is moist air, a lifting mechanism, and unstable atmosphere.
This High-pressure system sits off the coast of California and typically brings good flying weather to the region.
What is the Pacific High?
These types of clouds are produced along a cold front if there is enough moisture in the atmosphere.
What are cumulus clouds?
This is the difference between a funnel cloud and a tornado.
What is a one touches the ground?
This is a non-frontal narrow band of active thunderstorms.
What is a squall line?
One of these 3 conditions must be present for WA Tango to be issued.
What is moderate turb, surface winds greater than 30kts, or LLWS (non-convective)?
An atmospheric "river of air" must reach this many knots before it is considered a jet stream.
What is 50?
This thunderstorm is not associated with a front or pressure system
What is an air mass thunderstorm?
All TS imply these three elements.
What are Severe Turbulence, Severe Icing, and LLWS?
This weather model explains why we have similar weather around the world along lines of latitude.
What is the 3-cell model?
What is dust whirl?
What is hail greater than 3/4 inch, a tornado, or winds greater than 50 knots at the surface?
Other than severe Turb and Icing, a WS may be issued for these 3 conditions.
What are widespread Dust Storms, Sand Storms or Volcanic Ash.
These types of winds occur when cold dense air descends from the top of mountains.
What are Katabatic winds?
A frontal passage can be noted when these 3 conditions occur.
What are pressure, wind, and temp changes?
This type of cloud connects the TS to a tornado.
What is a wall cloud?
Cold descending wind from downdrafts creates this type of front that can create new TS.
What is a gust front?
These types of winds occur when air loses its moisture by rising on one side of the mountain and the other side becomes drier and warmer.
What are Chinook winds?
Freezing rain is associated with this type of front.
What is a warm front?
These 3 conditions are required for a tornado to form.
What is vertical wind sheer, TS, unstable atmosphere?
