right

The Coriolis effect causes winds to bend to the ___________________ in the northern hemisphere

produces strong winds

A steep pressure gradient

isobars

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

high winds

Closely spaced isobars indicate

light winds

Widely spaced isobars indicate

only wind direction

The Coriolis Effect influences

N & S Poles

The Coriolis Effect is strongest at the____________________.

counterclockwise toward the center

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

clockwise outward from the center

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

air would move directly from high to low pressure

If Earth were not rotating, ______________

Clear weather

High air pressure systems are usually associated with ______

precipitation

Low air pressure systems are usually associated with ______

clockwise toward the center

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

rising

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

falling

If "stormy" weather is approaching, the pressure tendency would probably be

westerlies

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

horse latitudes

Another name for the subtropical high pressure region is______

subtropical high

The Sahara and Australian deserts (among others) are associated with the

subtropical high

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

very dry, warm wind flowing down a mountain slope

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

day and flows toward the land

A sea breeze usually originates during the_____

evening and flows toward the water

A land breeze usually originates during the_____

jet streams

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

at 30°

The horse latitudes are

westerlies

Most of the United States is under the influence of the wind belt known as the

1013

Standard sea level pressure is __________millibars

29.92

Standard sea level pressure is ___________ inches of mercury

differences in air pressure

Wind is the result of

North, South

A north wind blows from the ________ to the ________

pressure

An isobar is a line on a weather map connecting places of equal

westerlies

Most of us living in the United States are under the influence of the wind belt known as the

anti-cyclone

A high-pressure center is called a(n)

cyclone

A low-pressure center is called a(n)

chinooks

Warm winds that move down the leeward side of mountains are known as

coriolis

The direction of winds is influenced by a force known as the _________ effect

trade

The surface wind zones that flow from the subtropics toward the equator are called the _________ winds

Right, Left

The Coriolis Effect cause winds to bend to the ______ in the N hemisphere, but to the ________ in the Southern hemisphere.

low

The Equator is a ________ pressure zone because the tendency of air is to rise.

easterlies/ westerlies

The Trade Winds are also known as the ________

equilateral low

The Doldrums are also known as the _______ pressure zone.

Northeast

If you are north of the center of low pressure, winds blow from

Northwest

If you are east of the center of high pressure, winds blow from the

False – Air pressure decrease by half every 18,000 ft

Air pressure decreases by half with every 18,000 miles of altitude.

False – Wind blows from high over the water to low pressure over land.

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

True

The Monsoon rains of south Asia are the result of sea breezes.

False – Winds blow down and away from center

Anticyclones characteristically have winds blowing toward their centers.

True

Because TIU is at an altitude of 600 feet above sea level air pressure here is less than 30 inches.

True

The wind belts and pressure zones of the earth move north and south as the seasons change.

False – Strongest at Poles

The Coriolis Effect is strongest at the equator and diminishes in strength near the poles.

True

The Coriolis Effect influences wind direction but not wind speed.

False – Clockwise out from center

In the Southern Hemisphere, the winds associated with a low -pressure system blow counterclockwise toward the center.

True

Because of Newton’s First Law, surface winds moving toward the equator move slower than the earth below.

False – Warm front west of Cold front

In a mature middle-latitude cyclone, the warm front is usually east of the cyclone.
