Questions from the lab handout are answered below:

1. Calculate the stability indices from the sounding that you plotted for May 3, 1999
     *see plotted sounding

2. What are the local times for the two gempak soundings?
         
12UTC=7am local time (left panel)                 00Z=7pm local time (right panel)

3. The most noticeable difference between the two soundings is the radiation inversion that resulted the night of September 19, 2009 (after 00Z 09/20).  By the 00Z sounding the radiation inversion has been mixed out due to adequate surface heating, evaporation and mixing of the air just above the inversion layer.

4. The temperature inversion is a radiation inversion.  Radiation inversions are created when the amount of outgoing solar radiation exceeds the amount of incoming.  This typically occurs during the night on clear nights and when calm winds prevail near the surface.

5. The temperature inversion was mixed out.  The atmosphere below the 800hPa level is well mixed.
