Air pressure - Answer average free exerted on a unit by molecular collision
What influences air pressure in the open atmosphere? - Answer 1. As altitude increases,
pressure decreases
2. As the amount of water vapor increases, air pressure decreases
3. As temperature increases, air pressure decreases
Pressure - Answer Decreases at the surface where air is rising
Increases at the surface where air is subsiding
What is a thermal low? - Answer warm rising air leads to low pressure
Dynamic low - Answer air converging at the surface, then rising, leads to low pressure
Thermal high - Answer cold subsiding air leads to high pressure
Dynamic high - Answer air converging at high altitude and then subsiding to the surface
leads to high pressure
Anticyclone - Answer Also called "high pressure systems."
Northern Hemisphere- clockwise & diverging
Southern Hemisphere- counterclockwise & diverging
Cyclone - Answer Also called "low-pressure system"
Northern Hemisphere-counterclockwise & converging
Southern Hemisphere-clockwise & converging
, Coriolis Effect - Answer Deflection of moving fluids and moving objects as a result of the
Earth's rotate.
1. Any freely moving object deflects to the right in the Northern Hemisphere, and deflects to
the left in the Southern Hemisphere.
2. Deflection is strongest at the poles and weakness progressively toward the equator (zero).
3. Proportional to the speed of the object.
4. Only influences the direction, not the speed
Friction - Answer 1. The frictional drag of the Earth's surface slows wind movement/speed,
and reduces the influence of the Coriolis Effect.
2. Wind friction is strongest at the surface.
Isobar - Answer line on a map joining points of equal atmospheric pressure
Intertropical Convergence Zone - Answer The region near/on the equator where the
northeast and southeast trades converge; associated with rising air of the Hadley cells and
frequent thunder storms
Subtropical High - Answer Large, semipermanent, high-pressure cells centered at about 30
degrees N and S over the oceans, which have average diameters of 3200km (2000 miles) and
are usually elongated east-west.
Jet stream - Answer A rapidly moving current of wind in the upper troposphere; the high-
speed "cores" of the hight altitude westerly wind flow that frequently meander in a north-south
direction over midlatitudes.
Doldrums - Answer Belt of calm air associated with the region between the trade winds of
the Northern and Southern hemispheres generally in the vicinity of the equator. The region of
the intertropical convergence-zone
Westerlies - Answer The great wind system of the midlatitudes that flows basically from west
to east around the world in the latitudinal zone between about 30 and 60 degrees north and
south of the equator
Polar easterlies - Answer A global wind system that occupies the area between the polar
highs and about 60 degrees of latitude. the winds move generally from east to west and are
