Atmospheric Forces

This is most likely a

• high pressure system

• low pressure system

• anticyclone

• geostrophic wind

The cause of all winds is the

• pressure gradient force

• Coriolis force

• geostrophic force

• gravity force

• friction force

Northerly winds will be deflected to the _____ in the Northern hemisphere due to the Coriolis force.

• north

• south

• east

• west

The pressure gradient force causes the winds to blow

• from west to east

• parallel to the isobars

• perpendicular to the isobars

• from low to high pressure

• from north to south

Sea level pressure of 1080 mb would be

• approximately average pressure

• weak high pressure

• weak low pressure

• strong high pressure

• strong low pressure

The record low pressure at sea level is approximately

• 1013 mb

• 990 mb

• 870 mb

• 500 mb

• 200 mb

This "side view" is likely a picture of a

• cyclone

• anticyclone

• low pressure system

• hurricane

• Coriolis system

The type of weather you could expect with this pressure system is:

• clear skies

• cloudy skies and precipitation

• strong winds

• blizzard-like conditions

This picture is most likely:

• a surface high pressure in the Northern hemisphere

• a surface low pressure in the Northern hemisphere

• an upper level high pressure in the Northern hemisphere

• a surface low pressure in the Southern hemisphere

• a surface high pressure in the Southern hemisphere

At what height in the atmosphere would you expect to find this pressure system?

• about 30,000 ft above the surface

• about 10,000 ft above the surface

• about 1,000 ft above the surface

• at the surface
