　　We develop a formally high order Eulerian-Lagrangian WENO finite volume scheme for nonlinear scalar conservation laws that combines ideas of Lagrangian traceline methods with WENO reconstructions.The particles within a grid element are transported in the manner of a standard Eulerian-Lagrangian(or semi-Lagrangian)scheme using a fixed velocity v.A flux correction computation accounts for particles that cross the v-traceline during the time step.If v=0,the scheme reduces to an almost standard WENO5 scheme.IMS-Th-E-22-3 17:00–17:30
