One of the early customers was the European Centre for Medium-Range Weather Forecasts, so, wild guess, they probably used it for medium-range weather forecasts.
FWiW Australia used a CDC Cyber 205 for occassional weather modelling and other mathematical work in the early 1980s.
( There was a seperate dedicated weather computer, this one was used for 'other' jobs like speculative weather modelling, monster group algebraic fun, et al.)
In 1980, the successor to the Cyber 203, the Cyber 205 was announced. The UK Meteorological Office at Bracknell, England was the first customer and they received their Cyber 205 in 1981.
Numerically, I’m currently what this would have looked like. I’m talking about the governing equation set, discretization methods, data, etc. It would be a fun project to try and implement a toy model like that.

If you really want a challenge, do it using pen, paper and a slide rule, like in the old days[1]. Just make sure to apply appropriate smoothing of the input data first[2].
