The Tiedke convection scheme (ref?) has been superseded by more advanced schemes (the "new physics"). It is however still possible to run LMDZ with it.

To run with Tiedke's convection scheme, one must set (in physiq.def)

iflag_con=2

In addition one must then specify a value of -2 or -1 to companion flag iflag_cldcon (also in physiq.def):

iflag_cldcon=-2

iflag_cldcon=-2 gives a better representation of low clouds radiative effect over the tropical oceans than iflag_cldcon=-1.
