In this paper,two formulation theorems of time-difference fidelity schemes for general quadratic and cubic physical conservation laws are respectively constructed and proved,with earlier major conserving time-discreti...
A tropical limited area multi-level primitive equation model,in which the time integral is performed with a split semi-implicit scheme,is presented.The operating time is shortened to one-third of the time the explicit...
