Exam 8: Atmospheric Circulation and Pressure Distributions

Atmospheric features that cover large portions of the earth and are maintained for weeks are considered

Define El Niño and Southern Oscillation and explain how they combine to affect weather in North America.

The trade winds are the result of:

Waves in the upper atmosphere are sometimes called:

Which of these winds is associated with the American Great Plains?

The ________ jet stream has a substantial influence on the weather of mid-latitude areas.

Winds blowing from west to east are called

Use the Sahel region to explain the consequences of the migration of the ITCZ.

Angular momentum is dependent upon all of the following,except:

Semipermanent high pressure cells tend to be located

When mountains cool rapidly at night,air flows into valleys,creating a ________.

Describe the forces that cause the movement of air through the Hadley cell,and discuss how the properties of the cell account for the weather at the ITCZ and subtropical high regions,and also the formation of the trade winds.

This is most prominent in summer:

Monsoons are most dramatic on this continent:

The ITCZ:

Wind speeds generally increase with height between the surface and the tropopause mostly because of:

Foehns:

Explain the conditions that prevent Asian monsoons in winter and allow them in summer.

The two major jet streams that impact weather in the northern hemisphere are the:

The single-cell model for general atmospheric circulation:
