Kalim and Christopher,
I have been trying and looking for a NCL code to calculate the
Richardson number as well as EDR just to get a feel for turbulence,
etc... in the atmosphere. I've been running the WRF, but haven't been
able to make/find a successful code yet. No luck so far over here. Any
thoughts or help would be much appreciated. Have a great day!

Dear Christopher,
You want to calculate local Richardson number let say:
Ri = ((9.8/T)*(dTdz))/(dUdz)^2
where T is potential temperature (K), gravitational accelration =9.8 ,
z is height, and wind speed:
U = (u*u + v*v)^(0.5)
If you need this I will send you acode of line.
good luck!

Hello,
Are there any existing functions knocking around which calculate
the Richardson number from measurements of wind speed, temperature and
humidity?
