Need for a shallow convection scheme in LMK: 1 July 2004 Testsuite 1-5 without shallow convection pressure jump problem operational LM the ‚truth‘ (?) Testsuite 1-6 with simple shallow convection param.
Basically, the LMK shallow convection scheme provides an upward moisture flux from the PBL to the free troposphere RH (with shallow convection) RH(with sh. conv) - RH(without sh. conv.)
