[RegCNET] why?

[Yanlb]

To anyone who may concern,
I ran two sets of RegCM simulations.
One with dt=150 450, the other with dt=180 540. The other parameters
of them are same.(dx=60)
I found the output of them quitely differentiate.
For example, the groud temperature difference of above two simulations
have reached up to 5 degrees over some areas.
Which is right? dt=150 or 180?
Does it mean that we should change dt for several times to choose the best
step by comparing with CRU?
Best regards,
Libin Yan
