Listing Program Exercises!!
- Try the one listing program we haven`t talked about, SFL604.
Are there any new variables? How do they work? What makes SFL604 different from
SFLIST? Display all data for Massachusetts on August 19, 1991 at 18 UTC.
Use the * qualifier until
the area is small enough so the data fits on one screen. Now list all the stations
that report mean sea level pressures less than 1000 mb at 18Z.
(Hint: Set SKPMIS = YES - Why?)
- List the surface temperature (in degrees C), the relative humidity, the mean
sea level pressure, the present weather symbol, and the visibility for the
Boston, MA (BOS) area at 18Z on August 19, 1991. Now list this data for just
the Boston station, at each hour in the file.
(Hint: Experiment with abbreviating the DATTIM format. Try using keywords for
DATTIM.)
- Use the sounding station map in the
Reference chapter to choose a sounding station. List the unmerged 0 Z data
on August 20, 1991 from that station. Now display wind speed and direction, height
and temperature in Kelvin for all pressure levels. Display your favorite stability
indices (For example, the showalter index.) Display these data again for just
the mandatory pressure levels. Now display the data on isentropic (theta)
surfaces.
