trpaus() computes tropopause level fields.
This routine computes tropopause data. At each mass point a surface up search is made for the first occurrence of a three layer mean lapse rate less than or equal to a critical lapse rate. This critcal lapse rate is 2 deg/km. This is in accord with the WMO definition of a tropopause. A maximum tropopause pressure of 500mb is enforced. Once the tropopause is located in a column, pressure, temperature, u and v winds, and vertical wind shear are computed.
