B) changes in air pressure over the Earth's surface.
C) movement of the air masses.
243.
Which thunderstorms generally produce the most severe conditions, such as heavy hail and destructive winds?
A) Warm front.
B) Squall line.
C) Air mass.
244.
What feature is associated with a temperature inversion?
A) A stable layer of air.
B) An unstable layer of air.
C) Air mass thunderstorms.
245.

A) 3,350 feet MSL.
B) 5,350 feet MSL.
C) 9,350 feet MSL.
246.
The most frequent type of ground or surface based temperature inversion is that produced by
A) radiation on a clear, relatively still night.
B) warm air being lifted rapidly aloft in the vicinity of mountainous terrain.
C) the movement of colder air under warm air, or the movement of warm air over cold air.
247.
What are the requirements for the formation of a thunderstorm?
A) A cumulus cloud with sufficient moisture.
B) A cumulus cloud with sufficient moisture and an inverted lapse rate.
C) Sufficient moisture, an unstable lapse rate, and a lifting action.
248.
Which weather phenomenon is always associated with a thunderstorm?
A) Lightning.
B) Heavy rain showers.
C) Supercooled raindrops.
249.
What is an important characteristic of wind shear?
A) It is an atmospheric condition that is associated exclusively with zones of convergence.
B) The Coriolis phenomenon in both high and low level air masses is the principal generating force.
C) It is an atmospheric condition that may be associated with a low level temperature inversion, a jet stream, or a frontal zone.
250.
What is an important characteristic of wind shear?
A) It is primarily associated with the lateral vortices generated by thunderstorms.
B) It usually exists only in the vicinity of thunderstorms, but may be found near a strong temperature inversion.
C) It may be associated with either a wind shift or a wind speed gradient at any level in the atmosphere.
