The weighted technique is introduced in the compact high-order nonlinear schemes (CNS) and three fourth-and fifth-order weighted compact nonlinear schemes (WCNS) are developed in this paper. By Fourier analysis, the dissipative and dispersive features of WCNS are discussed. In view of the modified w
