Dear NCL Experts,
I have a question regarding the computation of density from the WRF outputs. I specifically need to compute it for kinetic energy (rho * u_i^2).
Since density is not an output from WRF, I currently have:
Rho = ((pressure*100.)) /((287.0 *(1. + (0.608*qvapor))*temperature)).
However, I realize that there are Qvapor, qcloud, qrain, qice, qgraupel. Do I need to account for all the Qs? If so, how? I don’t suppose that I could just add them all up? Or is only Qvapor relevant for kinetic energy computations in a Hurricane?
Also, how do we not have an in-built NCL function for computing NCL already?
Sincerely,
Prashanth
