source: LMDZ5/trunk/libf/phylmd/cv3p1_closure.F90 @ 2284

Last change on this file since 2284 was 2253, checked in by jyg, 10 years ago

1/ Introduction of two variables in the ".def" files: (i) cvl_sig2feed is
the top of the convective feeding layer in sigma coordinates (D=0.97);
(ii) cvl_comp_threshold is the threshold fraction of convective points
below which compression occurs (D=1.).
2/ Corrections of various bugs revealed by the changes in compression:

  • correct bugs in cv3a_uncompress.F90 for 3 fields used for convective

scavenging.

  • add a reset to zero of "sig" and "w0" for non-convective points

(cva_driver.F90).

  • in cv3_routines.F90, correct bounds of a few loops in cv3_undilute2,

correct the reset of the no-convection counter in cv3_yield.

  • in phys_output_write_mod.F90, correct output of wdtrainA and wdtrainM.

3/ Improve declarations in various subroutines.
