An extensive body of air in which temperature and moisture characteristics are fairly uniform is a(n):

Hurricane formation in the south Atlantic and southeast Pacific is:

Most anticyclones move from:

Tornados are small but very intense anticyclonic flows with extremely high pressure in the center.

The distinguishing characteristic of continental air masses is that they are relatively _________.

As a cold front moves, it forces warmer air upward which can produce cumulus clouds and thunderstorms.

An extensive body of air in which temperature and moisture characteristics are fairly uniform over a large area is called an ________.

The figure labeled D shows the _______ of wave cyclone development.

In an anticyclone:

The two major criteria used to classify air masses are source regions and ________.

An air mass formed over north-central Canada would be classified as a continental polar air mass.

A front that involves lifting a warm air mass completely off the ground is a(n)________ front.

Air masses that form over oceans are classified as "humid" air masses.

Describe and compare cold and warm fronts.

Themost powerful and destructive type of cyclonic storm that produces heavy rainfall is the:

Cold fronts tend to be steeper and move more quickly than warm fronts.

This figure shows a cross section of a(n):

The cold front in this figure is labeled:

In an anticyclone, descending air is warmed adiabatically so there is little condensation and skies tend to be mostly clear.
