An observation by conventional sounding of temperature as a function of pressure was made at a
meteorological station. The text file, An observation by conventional sounding of temperature as a function of pressure was made at a
meteorological station. The text file, gefdhwdata.txt contains the data. A matlab code for
reading the data is given in the Appendix. The code and data will be posted separately. The first record
in the data p mb T deg C is the measurement taken at the surface. The elevation of the
station is mAt the surface, the height is already z m
a From the data, calculate and plot the vertical profiles of pressure p temperature T density
and potential temperature theta using ps mb as the reference pressure as a function of height. If
tropopause is defined as the location with the minimum of temperature, what is the height in meters
of the tropopause for this observed profile?
b Calculate and plot the vertical profile of the lapse rate of temperature, Gamma dTdz as a function of
height. Compare it to the dry adiabatic lapse rate, Gamma d gcp and use this as the basis to discuss the
dry static stability of the atmospheric column. Your result here should be consistent with the plot of
theta z from Part a Note that the stability criterion, Gamma Gamma d is equivalent to dtheta dz contains the data. A matlab code for
