advtrac.F90 @ 2004

Last change on this file since 2004 was 1987, checked in by Ehouarn Millour, 11 years ago
Add updating pressure, mass and Exner function (ie: all variables which depend on surface pressure) after adding physics tendencies (which include a surface pressure tendency). Note that this change induces slight changes in GCM results with respect to previous svn version of the code, even if surface pressure tendency is zero (because of recomputation of polar values as an average over polar points on the dynamics grid).
