Hello,
I'm a graduate student working on a project about the recent Pacific Northwest heatwave and am trying to calculate the potential temperature budget from a WRF simulation and have two questions.
1) I'm particularly interested in separating the horizontal and vertical advection tendencies. I've found the total advection tendency, called RTHFTEN, and am wondering if there's any way to extract the horizontal and vertical components separately?
2) When I calculate the residual of the theta equation as d theta / dt - advection - Q = Residual, I find that the residual is much larger near the surface and decreases with decreasing pressure. In the above equation advection is RTHFTEN and Q is the sum of other theta tendency terms (RTHBLTEN + RTHRATEN + RTHCUTEN + H_DIABATIC)
Any guidance on either of the two questions would be greatly appreciated, thank you for your time!
