help maintain the earth's heat
budget. True or false
true
2
The polar jet stream usually slows
down in winter. True or false
false
3
Katabatic winds have a cooling
effect, and chinook winds have a
warming effect. True or false
true
4
Sea breezes are more likely at night,
while land breezes are more likely
during the day. True or false
false
5
The bora and mistral are local
names given to chinook winds.
True of false
true
6
The wind called the "norther" in
Texas is really not a local wind but
rather is a synoptic scale (macroscale)
phenomenon. True of false
true
7
The existence of jet streams was
first determined by Ben Franklin as
the result of his kite experiments.
True or false
false
8
For much of South and Southeast
Asia, winter is a period
characterized by relatively dry
conditions. True or false
true
9
A sea breeze is usually best
developed early in the morning.
True or false
false
10
Westerly flow aloft is unrelated to
the earth's rotation. True or false
false
11
Jet stream winds are completely
distinct from the midlatitude
westerlies. True or false
false
12
Seasonal changes in pressure are
greater over continents than over
the oceans. True or false
true
13
The chinook wind has been known to
cause rapid increases in temperature
in the Denver, CO area. True or
false
true
14
The areas of abundant rainfall on
the earth tend to be
near the equator and in midlatitudes.
15
Why do westerly winds prevail at
upper altitudes?
rotation of the earth and equator to
pole temperature contrast
16
Surface high pressure zones are
usually associated with
clear or nearly clear weather.
17
Jet streams are associated with
fronts because of the
large temperature gradient.
18
Most of the United States is situated
in which zone of prevailing winds?
westerlies
19
When are upper air winds fastest?
in winter.
20
A Santa Ana (or Chinook or Foehn)
wind is a:
very dry, warm wind coming down a
mountain slope.
21
Summertime wildfires in California
are fanned by:
the Santa Ana winds.
22
The dishpan experiments:
revealed a wavy circulation pattern
when the pan was rotated.
23
Jet streams
occur at 25,000 to 40,000 feet in
middle latitudes.
24
Winds are usually named for:
the direction or place from which
they are blowing.
25
The region where the northeast
trades meet the southeast trades is
known as the
ITCZ.
26
The definition of the word
'monsoon' means
seasonal wind shift.
27
A primary factor causing monsoon
circulations is
greater temperature changes over
continents compared to oceans.
28
The amount of precipitation
received at a given location is
primarily controlled by
circulation patterns in the
atmosphere.
29
Chinook winds, land-sea breezes
and Santa Ana winds are examples
of ________ circulations.
mesoscale
30
The greater strength of jet stream
winds during winter is due to
greater horizontal temperature
contrasts.
