Fronts
A relatively moist, warm air mass slides up and over a cold air mass
What is a Warm Front?
How the atmosphere will react to vertical motion
What is Stability
Clouds associated with good visibility and turbulence
What is a Cumulus Cloud
The beginning stage of a thunderstorm
What is Cumulus
What is Radiation Fog
front associated with thunderstorms, heavy rain, and gusty winds
What is a Cold Front
A temperature increase with altitude that can trap pollutants and stabilize the atmosphere
What is an Inversion
Clouds associated with poor visibility and little to no turbulence
What is a Stratus Cloud
The flat, spreading top of a mature thunderstorm cloud, signaling strong updrafts
What is an Anvil Top
Fog that forms when warm, moist air moves over a cooler surface
What is Advection Fog
Two air masses that are not moving, moving very slowly, or pushing into each other
What is a Stationary Front
The deflection of winds due to Earth's rotation, influencing global wind patterns
What is the Coriolis Effect
This cloud could indicate possible mountain wave turbulence
A narrow band of active thunderstorms
What is a Squall Line
Fog that forms when moist air is forced up a slope and cools to the dew point
What is Upslope Fog
Front that forms when a fast moving cold front catches up to a warm front, lifting the warm air off the ground and often bringing complex weather patterns
What is an Occluded Front?
The change in atmospheric pressure over distance, which drives wind speed
What is the Pressure Gradient
Recommended distance to stay away from storm clouds
What is 20 miles
A large thunderstorm capable of producing tornadoes, large hail, and strong winds
What is a Supercell
Fog made of supercooled droplets that freeze on contact
What is Freezing Fog
Front that occurs when a warm front overtakes a cold front
What is a Warm Front Occlusion
What layer of the atmosphere doesn't get colder as altitude increases
What is the Stratosphere
Prefix/suffix for naming a rain cloud
What is Nimbo/Nimbus
A rotating updraft within a supercell thunderstorm, often a precursor to tornadoes
What is a Mesocyclone
A technique used at some airports involving chemicals, heaters, or turbulence to clear fog for operations
What is Fog Dispersal
