Weather Review - Part Two

Which best describes a characteristic of the jet stream?

• It forms a boundary between a cold air mass and a warm air mass.

• It creates the high winds around the eye of a hurricane.

• It forces the hot air along the equator to rise to areas in North America.

• It causes high pressure air masses to rotate clockwise.

Which best explains why North Carolina’s winter weather could vary from what is normally predicted during a La Niña event?

• A slight dip in the jet stream could bring colder weather.

• Prevailing westerlies will push air masses from west to east.

• Cold air from the Gulf Stream could interact with the jet stream and cause winter storms.

• Strong surface currents can push hurricane storms away from the North Carolina coastline.

Westerly winds moving across the deserts of the United States toward the East Coast most likely bring which types of conditions to North Carolina?

Why do most weather systems in the United States move from west to east?

• The West Coast is at a higher elevation than the East Coast, and weather systems go downhill.

• Prevailing winds carry weather systems to the east across most of the United States.

• The West Coast is warmer, and weather systems move from warmer to colder places.

• Mountain ranges prevent the movement of weather systems from east to west.
