Metr 201 Monteverdi Quiz #1

100 pts.

(Test will be collected at 10:05 AM)

 

A.  Short Answer and Definitions.  (5 points each for a total of 25 points in this section).

 

(a) The 500 mb level is found typically at what height (either in decameters or feet)  _18000 feet (564 dm)

 

(b)         The 700 mb level is found typically at what height (either in decameters or feet) __10000 feet (330 dm)

 

(c)         The study of the development of and evolution of atmospheric motions and circulation systems as solutions of the fundamental equations of hydrodynamics or other systems of equations appropriate to special situations is the definition of _dynamic meteorology

 

(d)         A contour of constant pressure is known as an __isobar

 

 

(f)  Synoptic Meteorology –The study and analysis of weather systems based upon analyses of a set and/or series of charts that contain a synopsis of weather observations at a given time. The understanding of these weather systems is based upon application of the principles of physical and dynamic meteorology.

 

 

 

B.      Units. (5 pts each for a total of 25 pts)

         Provide the metric system units used conventionally for the                             following:

        

                      ______m s-1_____________________

 

                       _____ m s-1______________________

 

                       ______ m s-2_____________________

 

                     _______ cm s-1____________________

 

                       _______ C or K0____________________

 

 

 

C. First Law of Thermodynamcs (30 points in this section).  The First Law of Thermodynamics, as we discussed it in class, is written out below.

 

 

Term 1        Term 2                 Term 3

 

 

1.    Write out the conceptual equivlaent of the First Law of Thermodynamics.  [Hint: the answer is NOT "the change in temperature equals the change in heat divided by the specific heat....etc...." (20 points)

The temperature changes experienced by an air parcel are due to temperature changes related to direct heating and cooling and/or temperature changes due to contraction or expansion.

 

2.    Term 2 is known as the ___diabatic or sensible heating/cooling____  term. (5 points)

 

3.    Term 3 is known as the ___adiabatic_______  term. (5 points)

 

 

D.  Short Essay.   (Answer below or in complete sentences, with subject, verb and object in each sentence, please.  You'll only need about three sentences here.  If you are writing more, you missed the point.)  (20 points in this section)

 

The philosophical underpinning of sounding analysis is something called “parcel theory.”  In a few sentences, briefly describe what is meant by “parcel theory.”

 

In parcel theory, one air parcel at the surface is assumed to have the same temperature and dewpoint of the environment at the surface, and then is lifted relative to the surrouding undisturbed environmental air.  Although parcel theory has its limitations, it has been shown to be successful in explaining thunderstorm development.
