To all ccm2 users:

I ran ccm2 for a 120-day simulation with a delta t of 30
minutes. Everything runs fine until the 5653th step and
then it says "original Courant limit exceeded at k, lat= 1
37 (estimate= 1.001), solution has been truncated to
wavenumber 29. What does this mean ? Is there an error or
should I disregard it ?
