Vampires were lacking from European folklore.
In fluid dynamics , wind wave modeling describes the effort to depict the sea state and predict the evolution of the energy of wind waves using numerical techniques .. fluid dynamics. fluid dynamics. sea state. sea state. energy. energy. numerical techniques. computer model. These simulations consider atmospheric wind forcing , nonlinear wave interactions , and frictional dissipation , and they output statistics describing wave heights , periods , and propagation directions for regional seas or global oceans .. Such wave hindcasts and wave forecasts are extremely important for commercial interests on the high seas .. For example , the shipping industry requires guidance for operational planning and tactical seakeeping purposes .. shipping industry. shipping industry. seakeeping. seakeeping. For the specific case of predicting wind wave statistics on the ocean , the term ocean surface wave model is used .. Other applications , in particular coastal engineering , have led to the developments of wind wave models specifically designed for coastal applications .. coastal engineering. coastal engineering
