WX201 Exam Revision Questions with 100%
Correct Answers.
The large thermally driven convection cell that is driven by convective "hot" towers along
the equator is the
Hadley Cell
The intertropical convergence zone is a region where
northeast trades meet the southeast trades
in Honolulu you would most likely experience winds blowing form the
Northeast
On a weather map of the Northern hemisphere, one would observe the westerlies
between the subpolar lows and the subtropical highs
the majority of the united states lies within this wind belt
Westerlies
On a weather map of the northern hemisphere, the trade winds would be observed
south of the subtropical highs
the position of the pacific high over the north pacific ocean shifts ______ in the winter and
______ in summer
Southward, northward
the worlds deserts are found at 30 degrees latitude because...
of the sinking air of the subtropical highs
Which of the following does not describe the subtropical jet stream?
forms along the polar front
Which does not describe the polar front jet stream
, is normally found at a higher elevation than the subtropical jet
In the northern hemisphere the polar jet stream is strongest when
Air north of the polar front is much colder than air south of the polar front
The jet stream flows
in a wavy pattern from west to east
as an air parcel aloft moves northward from the equator it moves closer to the earths axis
of rotation because of the conservation of angular momentum the air parcels motion should
increase in speed
the average winds aloft are strongest in
Winter
in the northern hemisphere ocean currents in the Atlantic and pacific move in a generally
circular pattern. The direction of this motion is _____ in the Atlantic and _____ in the
pacific
Clockwise,clockwise
A sea or land breeze is caused by
Temp Differences
The instrument that uses infrared or visible light in the form of a laser beam to determine
wind direction is the
Lidar
Surface winds are generally strongest and most gusty
in the afternoon
Clear Air turbulence can occur
Near a jet stream. in areas of mountain waves, where strong wind shear exists.
Thermal turbulence above the surface is usually most severe
