WX 301 Exam 2 ACTUAL Exam
Questions and CORRECT Answers
Given the above mean sea-level pressure surface chart with isobars drawn and labeled. What
would be the most likely direction of the surface winds at the x, assuming typical values of
surface friction? (Assume northern hemisphere) - CORRECT ANSWER - From the west.
The figure above shows five environmental lapse rates (ELRs). What would happen to an air
parcel forced to rise from the surface in an atmosphere represented by ELR 3 (yellow line)? -
CORRECT ANSWER - it would continue rising
The below picture depicts a field of wind observations in the northern hemisphere. Overlaid on
the wind observations are four cold fronts, only one of which is correct. Based on the winds
alone, which front is most correct? - CORRECT ANSWER - D

temperature contrast.
The atmosphere is typically most unstable _____. - CORRECT ANSWER - during the
mid/late afternoon
