DIAGNOSTICS momentum term signs/directions

#1 Unread post by komet7 »

I have a question about the momentum terms in diagnostics output. I am trying to figure out the directions of the terms in both across and alongshore components. I have a constant upwelling wind forcing. My grid direction is: (+) ONshore/Northward. When I calculate

accel-(cor+advection+prsgrd+mixing)

from the diagnostics I get zero, which one expects.

Does this mean to find the direction of each component, I have to multiply advection and coriolis terms with -1 as they appear on lhs of the equation in its original form?

thank you!

That's right. as you discovered everything but accel is on the rhs
