cv3p2_closure.F90 @ 2394

Last change on this file since 2394 was 2374, checked in by jyg, 9 years ago
Creation of a new closure routine for Emanuel convective scheme: cv3p2_closure.F90 (called when iflag_clos=3) is a cleaned up and reordered version of cv3p1_closure.F90. cv3p1_closure.F90 (called when iflag_clos=2) is kept for numerical compatibility with earlier versions.
