434!           .F.: linear extrapolations (conventional algorithm).
435!           .T.: stable extrapolations combining spatio-temporal extrapolations.
436! LELTRA  : if TRUE then use "elegant" algorithm to find departure point
437!           (only applicable in 2TL scheme for the shallow-water equations)
438! RW2TLFF : when computing the refined position of the origin point for
439!           Coriolis term, the new wind used is:
440!           0.5*RW2TLFF*(V(F)+V(O)) + (1-RW2TLFF)*V(M)
441

444!           terms.
445! XIDT    : pseudo-second order uncentering factor applied to linear terms,

449!           key used to allocate special buffer for needed quantities
450!           to transfer informations from predictor to corrector.
451
452! * Switches for use of quasi-monotone interpolations:
453! LQMW    :  Use quasi-monotone three-dimensional interpolations for wind
454! LQMHW   :  Use quasi-monotone interpolations in the horizontal for wind
455! LQMT    :  Use quasi-monotone three-dimensional interpolations for temperature
456! LQMHT   :  Use quasi-monotone interpolations in the horizontal for temperature
457! LQMP    :  Use quasi-monotone three-dimensional interpolations for cont. eq

470
471
472! * Treatment of Coriolis term:
473! LADVF   : if TRUE then use "advective" treatment of Coriolis terms (SL);
474!           in this case 2*Omega*Vec*r is computed analytically.
475! LIMPF   : if TRUE then use implicit treatment of Coriolis terms (EUL and SL)
476! L2TLFF  : if TRUE then use refined treatment of Coriolis term in 2TLSL scheme
477!           (can be currently used also with the 3TL SL vertical interpolating
478!           scheme).
479
480! * Change variable with an Eulerian treatment of orography:
481! RCMSLP0 : Real for tuning of the Tanguay/Ritchie correction in SL continuity
482!           and temperature equations for 3D model.
483
484! * Treatment of MF simplified physics in the semi-Lagrangian TL and AD codes.
485
486! LSL_UNLPHY_F : if TRUE diabatic terms are evaluated at the final point F.
487!                if FALSE diabatic terms are evaluated at the orig point O.
488!                Remark: this variable is involved only in MF physics.
489
490! * Switch for computation of Moisture Convergence for French deep convection scheme
491
492! NCOMP_CVGQ   :  0 ==> Compute the CVGQ in an Eulerian manner, using spectral
493!                       moisture stored in the YQ GFL variable.
494!                       In this case YQ must be spectral and
495!                       horizontal derivatives are used.
496!                 1 ==> Compute the CVGQ in an Eulerian manner, using spectral
497!                       moisture stored in the YCVGQ GFL spectral variable and
498!                       its horizontal derivatives.
499!                       This case is well designed for the case where YQ is
500!                       a purely grid-point GFL.
501!                 2 ==> Compute the CVGQ in a semi-Lagrangian manner
502!                       (Lagrangian tendency - Eulerian tendency), using data
503!                       stored in the YCVGQ grid-point variable.
504!                       This case is well designed for the case where YQ is
505!                       a purely grid-point GFL, and where LSLAG=T.
506! remark ky: better to move this variable in SUDYNA/NAMDYNA/YOMDYNA in the
507!  future to make it available in SUDIM1 when reading NAMGFL.
