	67	!! ** Purpose : Compute the now trend due to the advection of tracers
	68	!! and add it to the general trend of passive tracer equations.
	69	!!
	70	!! ** Method : The advection is evaluated by a second order centered
	71	!! scheme using now fields (leap-frog scheme). In specific areas
	72	!! (vicinity of major river mouths, some straits, or where tn is
[457]	73	!! approaching the freezing point) it is mixed with an upstream
[3]	74	!! scheme for stability reasons.
[457]	75	!! Part 0 : compute the upstream / centered flag

	77	!! Part I : horizontal advection

	95	!! Uh.gradh(T), i.e.
[2528]	96	!! save trend = ztra + ptn divn
[3]	97	!!
	98	!! Part II : vertical advection
	99	!! For temperature (idem for salinity) the advective trend is com-
	100	!! puted as follows :
[2528]	101	!! ztra = 1/e3t dk+1[ zwz ]
[3]	102	!! where the vertical advective flux, zwz, is given by :

[2528]	105	!! zupsv = upstream flux = wn * (ptb(k) or ptb(k-1) ) [wn>0 or <0]
[3]	106	!! zcenu = centered flux = wn * mk(tn)
[457]	107	!! The surface boundary condition is :
[1528]	108	!! variable volume (lk_vvl = T) : zero advective flux
[2528]	109	!! lin. free-surf (lk_vvl = F) : wn(:,:,1) * ptn(:,:,1)
[3]	110	!! Add this trend now to the general trend of tracer (ta,sa):
