Re: Calculating Richardson number

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?
