Exam 6: Air Pressure and Winds

Instructions: Choose one answer from each pair of selections. Pressure decreases most rapidly with increasing altitude in WARM | COLD air because the air has high density.

When the flow of air is purely geostrophic, how can the wind speed be described and how is this represented on an isobaric map?

The wind around a surface low pressure center in the Southern Hemisphere blows ____.

A wind that blows at a constant speed parallel to curved isobars or contour lines is called a ____.

Suppose that the winds aloft in the Northern Hemisphere are geostrophic and blowing from the north. Low pressure is located to the ____.

Instructions: Choose one answer from each pair of selections. Rising air motions are associated with surface centers of HIGH | LOW pressure in the Northern and Southern Hemispheres.

An altimeter is often just an aneroid barometer that has been calibrated to indicate altitude.

A ____ usually indicates clearing weather or fair weather.

The most practical location for building a wind turbine would be ____.

On an upper-air chart, the wind aloft tends to blow ____.

Explain why and how altitude corrections are made to barometer readings.

The ____ is an apparent force created by the earth's rotation.

In the vertical, the pressure gradient force points ____ and gravity points ____.

Discuss the pros and cons of harnessing wind energy using wind turbines, and whether you think this is a viable solution for meeting the energy demands of people.

To correctly monitor horizontal changes in air pressure, the most important correction for a mercury barometer measurement is the correction for ____.

Atmospheric pressure changes ____.

Which of the following combinations produces the strongest Coriolis force?

A wind blowing at a constant speed parallel to straight line isobars with the pressure gradient force (PGF) and the Coriolis force in balance is called a ____.

The pressure gradient force is directed from higher pressure toward lower pressure ____.

Instructions: Choose one answer from each pair of selections. The horizontal movement of CIRRUS | FOG clouds is more influenced by friction.
