This paper presented a new semidiscrete central scheme for hyperbolic system of conservation laws. By using the fourthorder CWENO reconstruction, the new scheme has properties of higher order accuracy and high resolution for discontinuities. Because the new scheme has less dissipation, which is independent of timesteps, than the staggered central scheme, it can be efficiently used with timesteps as small as the requirement of the numerical stability.
