Lax-wendroff differencing scheme

From Glossary of Meteorology



Lax–Wendroff differencing scheme

An explicit numerical approximation to the time evolution of fluid flows that is constructed through Taylor expansions to yield second-order truncation error using only two consecutive time levels.

The resulting approximation introduces a diffusive damping term that helps control nonlinear computational instability and may be useful for equations with shock discontinuities.
