Exam 9: Weather Patterns

Typically, upper- level air flow is slower over anticyclones than over cyclones.

Middle- latitude anticyclones in the Northern Hemisphere:

The FIRST sign of an approaching warm front is the appearance of nimbostratus clouds.

The energy of a mid- latitude cyclone comes mainly from:

After a cold front passes, which of these does NOT usually occur?

Surface winds for an anticyclone are convergent.

People usually pay more attention to cyclones than they do to anticyclones.

A dryline causes uplift to occur because:

Compared to warm fronts, cold fronts have:

The wind direction in a low pressure system is:

Why does occlusion lead to the demise of a mid- latitude cyclone?

Each of the statements refers to the approach or to the passage of a front. If the statement refers to the approach of a typical cold front, use the letter A for your answer. If the statement refers to the approach or passage of a typical warm front, use the letter B. If the statement applies to both, answer with letter C. -Long lasting, steady rainfall

In the United States, the air mass most commonly found at the back of a cold front is:

-Refer to the diagram of a front shown above. If the warm air at the back is stable, what kind of cloud is most likely to form and produce precipitation in association with the front?

All of the following are common locations for cyclongenesis EXCEPT for:

The development of major winter storms in the midwest depends strongly on:

A wind shift in a clockwise direction, as from south to west, is termed wind shift.

Occluded fronts characterize the beginning stages of a middle latitude cyclone.

Which of the following lists the stages of the mid- latitude cyclone life cycle in the proper order?

A ridge aloft is generally associated with:
