Standard sea level pressure in millibars is

1013 mb

Standard sea level pressure in inches of mercury is

29.92

The mercurial barometer was invented by

Torricelli

Which of these instruments is NOT used to measure air pressure?

a)mercurial barometer

b)aneriod barometer

c)barograph

d)anemometer

Anemometer

An altimeter is an adaptation of the

aneroid barometer

The force that generates wind is

pressure gradient force

Which of these factors influence the magnitude of the Coriolis force?

a)wind speed

b)latitude

c)wind direction

d)both wind speed and latitude

both wind speed and latitude

Lines on a weather map connecting places of equal air pressure are called

Isobars

Closely spaced isobars often indicate

high winds

A steep pressure gradient

produces strong winds

Widely spaced isobars often indicte

light winds

The Coriolis effect influences

light winds

In the Northern Hemisphere, the winds associated with a low pressure system (cyclone) blow

COUNTERCLOCKWISE and TOWARD the center

In the Northern Hemisphere, winds associated with a high pressure system blow

CLOCKWISE and OUTWARD from the center

If Earth were not rotating

air would move directly from high to low pressure

Upper air winds

are generally faster than surface winds

High air pressure systems are usually associated with

a)diverging winds

b)decending air

c)clear weather

d)all of these

All of these

Low air pressure systems are usually associated with

precipitation

In the Southern Hemisphere, the winds associated with a low pressure system blos

CLOCKWISE and TOWARD the center

If "fair" weather were approaching, the pressure tendency would probably be

Rising

If stormy weather were approaching, the pressure tendency would probably be

falling

Most of the United States is situated in which zone of prevailing winds?

Westerlies

Another name for the area of equatorial lows is the

Horse latitudes

This pressure zone is associated with abundant precipitation and warm temperatures.

equatorial low

The subpolar low (polar front) is

A zone where the polar easterlies and the westerlies converge

When are upper air winds faster?

in WINTER

A Santa Ana (or Chinook or Foehn) wind is a

very dry, warm wind flowing down a mountain slope

A sea breeze usually originates during the

day and flows toward the land

A land breeze usually originates during the

evening and flows toward the water

Fast moving currents of air found near the top of the troposphere are called

Jet streams

What is the technical name for a high pressure center?

Anticyclone

Low pressure systems are usually associated with clear weather

FALSE

Cyclones are usually associated with stormy weather

TRUE

If the barometer indicated 1020 millibars, air pressure would be considered high

TRUE

The Coriolis effect is strongest at the equator and diminishes in strength poleward.

FALSE

The pressure gradient force is the driving force behind wind.

TRUE

A southwest wind blows toward the northeast.

TRUE

An isobar is a line connecting places of equal humidity.

FALSE

Anticyclones characteristically have winds blowing out from their centers.

TRUE

The ultimate cause of a sea breeze is the unequal heating of land and water.

TRUE

Horizontal movement of air is called wind.

TRUE

A mountain breeze is best developed in the hottest part of the day.

FALSE

The region where the trade winds meet is also called the DOLDRUMS

TRUE

Most of the people living in the United States are under the influence of the wind belt known as the westerlies.

TRUE

Closely spaced isobars indicate high wind speeds.

TRUE

In the Northern Hemisphere, winds blow clockwise and outward from the center of anticyclones.

TRUE
