JYG, 20160513 : Introduction of the Effective Lifting Power (ELP), which ! takes into account the area (cv_feed_area) covered by thermals contributing ! to each cumulonimbus. ! The use of ELP prevents singularities when the trigger probability tends to ! zero. It is activated by iflag_clos_bl = 3. ! The ELP values are stored in the ALP_bl variable. ! !+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ! !! !! Control of the multiplication of no-trigger probabilities between calls !! to the convection scheme. If multiply_proba_notrig is .false., then !! proba_notrig is set to 1 at each call to alpale_th, so that only the last call !! plays a role in the triggering of convection. If it is .true., then propa_notrig !! is saved between calls to convection and is reset to 1 only after calling the !! convection scheme. !! For instance, if the probability of no_trigger is 0.9 at each call, and if !! there are 3 calls to alpale_th between calls to the convection scheme, then the !! probability of triggering convection will be 0.1 (= 1.-0.9) if !! multiply_proba_notrig is .false. and 0.271 (= 1.-0.9^3) if multiply_proba_notrig !! is .true. !!
