Exam 6: Atmospheric Pressure, wind, and Global Circulation

What are the defining characteristics of a high-pressure system?

The Polar high is always centered over the Poles.

The warming of the air around the Equator is responsible for the zone of high pressure known as the equatorial trough.

Gyres are large oceanic circulatory systems that form because currents are deflected by landmasses.

In a high-pressure system,surface air converges in a clockwise direction in the Northern Hemisphere..

Converging trade winds flow toward the ITCZ,which shifts back and forth across the Equator over the course of the year.

In general,the surface winds underneath the Ferrel Cell's Midlatitudes are

In which direction do surface winds of the tropical Northern Hemisphere flow?

In which of the following diagrams is the subsolar point located over the Tropic of Capricorn?

Cyclones and anticyclones are linked together in a convection loop consisting of air masses that spiral due to the Coriolis force.

Select all of the following statements that are true about high- and low-pressure systems.

The combined processes of __[1]____ and ___[2]___ are the overall method through which heat is distributed around the planet. Answer 1 Choices advection conduction convection radiation Answer 2 Choices advection conduction convection radiation

In a high-pressure system,surface air diverges in a clockwise direction in the Northern Hemisphere.

What is the average air pressure at mean sea level for the planet?

If you are experiencing winds that are described as "westerlies," the winds are flowing from which direction?

In a high-pressure system,surface air converges in a counterclockwise direction in the Northern Hemisphere.

As air descends it __[1]___ and can hold __[2]___ moisture. Answer 1 Choices: cools warms Answer 2 Choices: less more no

A low-pressure system is often associated with ____[1]_____ because ____[2]_____ and can hold less moisture. Answer 1 Choices: fair weather storm weather Answer 2 Choices: descending air cools rising air cools rising air warms up

High-pressure systems are referred to as cyclones.

Westerlies,winds flowing to the west,are the primary winds of the Midlatitudes.
