[RegCNET] the timestep in RegCM3

[zou liwei]

Dear ALL,

       Sorry for disturbing you.

       I am confused about the timestep in RegCM3. The folling is my case.

       In the "regcm.in",  we specify every step is 100s (variable "dt" in
model ). At the first step, "dt" is really 100s, however, when the model
goes to the second step, "dt" is changed to 200s (double of 100s).

       We note that the  "dt"  have been changed to 2*dt in temd.f. WHY?

      Would anybody give me some suggestion, please?

       Thank you in advance.

      Best Wishes,

      Liwei
