[gradsusr] Diabatic heating

[Anubhav Choudhary]

Dear Rai ji,

you can calculate diabatic heating using this formula- which is a rate of
conversion of theta (potential temperature) to absolute temperature

there is one more method by Yanai et al. (1973) --

further, you can read these papers --

Reanalyses, and NCAR CCM3 Simulation*
