Chapter 22-24 Part 1 Flashcards
“Anvil head” is a term applied to
cumulonimbus clouds.
A cT air mass is
warm and dry.
A dark gray cloud that blankets the sky and often generates precipitation is called
nimbostratus.
After the center of a mature wave cyclone passes, you should expect
barometric pressure to rise.
Air may best be described as
a mixture.
An air mass from the Gulf of Mexico is labeled
mT.
An mP air mass is
humid and cold.
Cold fronts and warm fronts in the middle latitudes are often associated with a
middle-latitude cyclone.
High air pressure systems are usually associated with
all of these.
High clouds that form delicate veil-like patches or extended wispy fibers are termed
cirrus.
Hurricanes generally are
all of these.
In the Northern Hemisphere, tornadoes are most frequent during the
April-June period.
In the Northern Hemisphere, winds associated with a high pressure system blow
clockwise and outward from the center.
Lines on a weather map connecting places of equal air pressure are called
isobars.
Low air pressure systems are usually associated with
precipitation.
Most of the United States is situated in which zone of prevailing winds?
westerlies.
On a weather map, _______ fronts are shown by a line with semicircles extending from one side.
warm.
On a weather map, _______ fronts are shown by a line with triangular points on one side.
cold.
Ozone filters out most of the _______ radiation in sunlight.
ultraviolet.
Ozone is concentrated in the
stratosphere.
Practically all clouds and storms occur in this layer of the atmosphere.
troposphere.
The Coriolis effect influences
both wind speed and wind direction.
The air masses that have the greatest influence on weather conditions in the central United States are
cP and mT.
The change of state from a gas to a liquid is called
condensation.
