Question 1

A northeaster along the east coast of the United States is best developed when a low pressure area
A) moves from west to east over Canada.
B) moves eastward over the Great Lakes.
C) moves northward over Ohio.
D) moves northeastward from the Texas panhandle.
E) moves northeastward over the Atlantic Ocean adjacent to the coast.

Accepted Answer

Northeasters typically form when low pressure systems move northeastward over the Atlantic Ocean, near or parallel to the east coast of the United States. This allows for moisture from the ocean to interact with cold air from the north, leading to precipitation and strong wind gusts. The other options do not provide the necessary conditions for a northeaster to develop along the east coast.

Question 2

A sea breeze is most likely to develop along a coastline when
A) away from the shore,pressure gradients are large.
B) away from the shore,pressure gradients are small.
C) it is raining.
D) it is foggy.

Accepted Answer

A sea breeze is a localized wind that blows from the sea towards the land due to temperature differences. During the day, the land heats up faster than the water, causing the air to rise and create a low-pressure area over the land. At the same time, the water remains cooler and creates a high-pressure area over the ocean. This pressure gradient sets up a sea breeze, where air flows from high pressure to low pressure. Therefore, the pressure gradients away from the shore should be small for a sea breeze to develop.

Question 7

Strong winds blowing over vegetation results in
A) physically damaged plants.
B) decreased crop productivity.
C) rapid water loss.
D) all of the above

Accepted Answer

Strong winds can physically damage plants by breaking branches, uprooting the entire plant or causing tissue damage. This can result in decreased crop productivity. Additionally, strong winds can create rapid water loss in the plant by increasing transpiration rates. Hence, all of the above options are correct.

Question 8

On the eastern side of the Rocky Mountains,chinook winds are driest when
A) clouds form and precipitation falls on the upwind side of the mountains.
B) the air aloft is cold.
C) the sun is shining.
D) the winds are blowing from the east.
E) surface friction is greatest on the downwind side of the mountain.

Accepted Answer

Chinook winds are driest when clouds form and precipitation falls on the upwind side of the mountains because the air loses moisture as it rises and cools, leading to dry conditions on the leeward side.

Question 9

List the scales of atmospheric motion from largest to smallest and give an example of each.From what you know about the various types of wind systems,are the size and duration related?

Accepted Answer

The answer of List the scales of atmospheric motion from...

Question 10

Good hang-gliding conditions require
A) thermal turbulence.
B) upward air motions.
C) molecular viscosity.

Accepted Answer

Hang-gliding requires upward air motions, also known as thermals, in order to stay aloft. Thermal turbulence can be a helpful indicator of these upward air currents, but it is not a necessary condition in itself. Molecular viscosity, which refers to the resistance of a fluid to flow, is not relevant to hang-gliding conditions.

Question 11

What is meant by the term monsoon wind system? Briefly describe or sketch the wind and pressure pattern during the summer and winter monsoon in Asia.

Accepted Answer

The answer of What is meant by the term monsoon...

Question 12

Which of the following is a serious hazard to aircraft?
A) molecular viscosity
B) laminar flow
C) clear-air turbulence
D) longwaves in the westerlies
E) none of the above

Accepted Answer

Clear-air turbulence poses a serious hazard to aircraft as it cannot be detected by radar or visual cues and can result in severe turbulence that can cause injury to passengers and crew, as well as damage to the aircraft. Molecular viscosity and laminar flow are factors that affect aerodynamics but do not pose a direct hazard to aircraft. Longwaves in the westerlies refers to atmospheric patterns and is not a hazard to aircraft.

Question 13

Briefly sketch or describe the formation of a chinook wind.Would you expect chinook winds to form more often on the eastern or the western slopes of the Cascade Mountains in Oregon?

Accepted Answer

The answer of Briefly sketch or describe the formation of...

Question 14

The land/sea breeze,lake breeze,and mountain/valley breeze are examples of
A) thermal circulations.
B) mechanical circulations.
C) atmospheric longwave circulations.

Accepted Answer

The land/sea breeze, lake breeze, and mountain/valley breeze are all examples of thermal circulations. These circulations occur due to differential heating of land and water or of mountain and valley regions, which leads to the generation of localized winds.

Question 15

How might knowledge of the direction of the prevailing wind at a given location be used in landscape design or the design of an energy efficient home?

Accepted Answer

The answer of How might knowledge of the direction of...

Question 16

Which of the following conditions favor the development of dust devils?
A) hot,moist days
B) hot,dry days
C) cold,moist days
D) cold,dry days

Accepted Answer

Dust devils are created by rising warm air that is heated by the ground. This rising air causes a spinning motion that can pick up dust and dirt from the ground. Since hot and dry conditions promote the heating of the ground and the rising of warm air, they are the most favorable for the development of dust devils.

Question 17

Briefly sketch or describe the conditions that lead to the formation of a Santa Ana wind.Is the Santa Ana wind dry or moist,warm or cold?

Accepted Answer

The answer of Briefly sketch or describe the conditions that...

Question 18

Santa Ana winds warm by ____ as they flow down an elevated desert plateau.
A) expansion
B) compression
C) evaporation
D) both expansion and evaporation

Accepted Answer

As the Santa Ana winds flow down an elevated desert plateau, they compress and warm up, leading to higher temperatures and dry conditions. Expansion and evaporation do not play a significant role in this process.

Question 19

Chinook winds are
A) warm,dry downslope winds.
B) warm,moist downslope winds.
C) cold,dry downslope winds.
D) cold,moist downslope winds.
E) warm,dry upslope winds.

Accepted Answer

Chinook winds are warm and dry downslope winds that occur in the western United States and Canada. They are often associated with rapid temperature changes and can cause snow to melt rapidly.
