What units does the metric (CGS) system measure?
length, weight & time respectively.
What is the difference between weight and mass?
Weight is a function of gravitational force.
Mass is a function inertia/acceleration.
What does a dyne measure?
force
What are sunspots?
Sunspots are regions of strong localized magnetic fields and indicate relatively cool areas in the photosphere
In the Southern Hemisphere, approximately what date will the greatest amount of incoming solar radiation be received?

What percent of the earth's insolation do land and water absorb?
%51
What is the effect on a polar air column in relation to a column of air over the equator?
An air column over the poles is thinner than an air column over the equator.
What is the definition of pressure?
Pressure is the force per unit area
With a sea level pressure reading of 1000 mb, what would be the approximate pressure at 18,000 feet?
With a sea level pressure reading of 1000 MB, the approximate pressure at 18,000 ft will be 500 MB.

Name the 3 states in which moisture in the atmosphere may be found.
solid, liquid & gaseous
What is the primary source of atmospheric moisture?
the oceans
What is the difference between relative humidity & absolute humidity?
RH: ratio percentage between water vapor actually present & water vapor necessary for saturation at a given temperature.
AH: amount of water vapor present per unit volume of space.
What is the definition of mixing ratio?
The ratio of the mass of water vapor to the mass of dry air.
What information does the dew point temperature provide to meteorologists?
The temperature that the air must be cooled, at a constant pressure and constant water vapor content, in order for saturation to occur.
