*† ‡ § ** †† A computationally efficient acoustic ray-tracing code based on unstructured adaptive grids is described in detail. The use of unstructured grids allows wave propagation simulations on complex computational domains. Detailed surface layer physics is included to take into account the atmospheric variability under different stability conditions and landuse inhomogeneities. The ray-tracing model has been coupled with meso- and microscale atmospheric flow models. The method shows promise in simulating long-range acoustic wave propagation in the atmosphere over complex terrain. |
