Wind speed is determined mainly by:
Pressure gradient force
During the winter season in Edwardsville, sudden drops in temperature during the daytime are often associated with:
passage of cold Canadian air mass
The pressure gradient force causes wind to move from centers of high pressure to centers of low pressure
Directly across isobars
The largest portion of energy that the earth receives from the sun comes as:
visible light and shortwave infrared radiation
The earth and sun both emit radiation, but they do so at largely different wavelengths. Why?
the sun is hotter than the earth
The ______ refers to the reflectivity of a surface.
Most energy emitted by the earth's surface
is absorbed by the atmosphere
Compared to a land surface subject to the same heating, an ocean surface should
have a seasonal temperature cycle lagging behind the land's seasonal temperature cycle
The vertical transfer of heat from one point to another by a moving substance is called
On an annual basis, which of the following latitudes is net radiation surplus?
A temperature inversion is a situation where
temperature increases with increasing altitude
In North America, one might expect to find the greatest annual temperature range
in eastern Alaska and northwest Canada
are caused by cold air drainage off of ice sheets and other cold areas
is confined to the tropics and subtropics
We measure air pressure using a(n) _____.
The "mistral", "taku", "bora" are local names for a gravity flow wind which is properly termed _________ wind.
The wildfires experienced in summer in California are known to be accelerated by the high speed, high temperature and extreme dry local wind called:
A local dry wind occurring to the leeward side of the Rocky Mountains and often with high capacity to evaporate snow is
The sea breeze occurs when the pressure gradient force
is from ocean to land
In the southern hemisphere the coriolis effect always acts to turn the flow of air
to the left
In winter, the average barometric pressure over north-central Asia (Siberia) is generally described as:
An east-west trough of pressure, 1011 to 1008 mb, lying approximately over the equator is generally referred to as:
What pressure center exists over the North Pacific during the winter season?
According to Wien's Displacement Law, the wavelength of maximum emission is inversely proportional to the absolute temperature of the radiating body, hence cold bodies tend to radiate more:
A body that emits the maximum amount of radiation possible at every wavelength for its temperature is called:
The lower latitudes receive much more solar energy than temperate zones because of:
Higher solar altitude
The sky is blue because of a phenomenon known as:
Which of the following statements about the distribution of insolation on the earth's surface is not correct?
All places beyond the tropics have a single peak of insolation often recorded about winter solstice
Most of the energy gained by the atmosphere is re-radiated to the earth surface in the form of:
The most important function of the general circulation of the atmosphere is to:
Even out the imbalance of heat between the low and high latitudes
The main surface currents in the major ocean basins assist in the heat transfer around the world by moving:
Cool water from the poles to the tropics.
An example of climate (versus weather) for a given area is:
The average rainfall in April is 15 inches
Temperature decreases with increasing elevation in which thermal atmospheric layers?
Troposphere and mesosphere
_______ is the most plentiful variable gas in the atmosphere. However, it varies in location, not in time.
Oxygen accounts for what proportion of the volume of gases in the atmosphere?
If a wind of 55 mph were subjected to a Coriolis force that is double what exists on earth, what would its new speed be?
The aurora borealis typically occurs in:
Which of the following is a example of a secondary pollutant?
Ozone is depleted by CFCs. What is the primary atom in the CFC molecule that is responsible for ozone depletion?
Los Angeles, California and Dallas, Texas have vastly different climates, despite existing at the same latitude. What causes this difference?
Dallas is continental; LA is maritime.
