Question 1
10 / 10 pts
Match each weather phenomena listed below to its appropriate scale of motion.
a large hurricane that impacts Florida and the Gulf of Mexico for over a week
the polar jet stream
a Santa Ana wind event
a wind gust
Question 2
7 / 7 pts
Which statement concerning the planetary boundary layer is true?
it is the layer of atmosphere influenced by surface friction
its depth typically extends to over 10,000 feet above ground level
it is the layer of atmosphere directly affected by upper level wind features
its depth is not affected by surface heating or terrain
Question 3
7 / 7 pts
As wind velocity increases, the force of the wind over an area increases by the same proportion.
True
False
Question 4
7 / 7 pts
Thermal circulations are produced:
only on the global scale, i.e., the Hadley cell
due to radiational heating and cooling in the upper troposphere
by the heating and cooling of the atmosphere near the ground
only at coastlines and in mountainous regions
IncorrectQuestion 5
0 / 7 pts
Which of the following correctly describes the typical sea breeze circulation?
surface winds blow parallel to the coastline, with the warmer air to the left of the wind direction
surface winds blow from land to sea
at the surface, low pressure forms over the ocean while high pressure develops over land
air rises over land and sinks over the ocean
Question 6
10 / 10 pts
Match each description with the correct name of the local wind system being described.
warm, dry downslope wind affecting Southern California
winds blowing from a valley up a mountain slope
a seasonally changing wind
rotating column of air that forms on a clear hot day over a dry surface
IncorrectQuestion 7
0 / 7 pts
Based on meteorology conventions for describing wind direction, which one of the following
statements is correct?
A land breeze is an offshore wind.
A mountain breeze is an upslope wind.
Along the eastern slopes of the Rocky Mountains, an upslope wind is a west wind.
An east wind blows toward the east.
Question 8
7 / 7 pts
When __________ is added to the single cell model of global circulation, the single cell
convection system becomes a three cell convection system.
Earth rotation
differential heating between land and water
the pressure gradient force
Earth axis tilt
Question 9
7 / 7 pts
In the three-cell model of global circulation, surface winds diverge in the vicinity of:
the equator
subpolar lows
the polar front
the north and south poles
Question 10
7 / 7 pts
Significant cloudiness and rainfall exist along the inter-tropical convergence zone and polar front
because air primarily ______ at these locations.
rises
sinks
Question 11
10 / 10 pts
Characteristics of the Northern Hemisphere sub-tropical jet stream include: (Choose all that
apply.)
found farther north than the polar front jet stream
forms along the poleward side of the Hadley cell
forms due to conservation of angular momentum of poleward moving air
found at a lower altitude than the polar front jet stream
Question 12
7 / 7 pts
Ocean circulation drives atmospheric wind patterns.
True
