Hello,

I am working with OpenIFS CY43R3 in its aqua planet configuration and trying to add a stationary localized heat perturbation which would mimick convective heating in the tropical mid-troposphere.

My intention is to get an ensemble of short-time simulations (order of few days) to analyse the short-time, near-field response.

I have a few ideas how to implement this, but I am unsure which one would be the easiest. First of all, I was thinking of nudging a temperature field which would contain this localized heating. 

Secondly, I believe it is also possible to add an additional temperature tendency to the righthand side of the temperature equation, however this seems quite technical.

Lastly, the upper air initialization file could also be formed in such way that it contains a heat source, however it should be there throughout the whole simulation not only in the initial time.

Which way would be the easiest to proceed?

Best Regards,
