%X Asselin-Robert time filter used in leapfrog time differencing scheme for deleting computing solution can degrade the accuracy of the calculations. The second-order Runge-Kutta method is not subject to time splitting and has the same accuracy as leapfrog scheme. A new Eular-forward semi-implicit atmospheric general circulation model with the spectral method is developed from NCAR CAM3.0 (Community Atmosphere Model 3.0).Using the second order Runge-Kutta method as the alternative method to leapfrog scheme and...
