Simulations with more efficient breakup tend to have higher domain-mean precipitation rates under both moderate and higher (0.0064 s−1) shear, despite the smaller mean drop size and hence lower mass-weighted fall speed and higher evaporation rate for a given rainwater content. In these runs, higher evaporation leads to stron... The simulated ocean waves of the Phillips spectrum can reflect the wind speed and direction influence on the wave, but they cannot reflect the fetch length effect. The simulated waves of the JONSWAP-Poisson spectrum can embody the effect of the wind speed, wind direction, and fetch length on the wave. The frame rates of the two spectra are equal.An ocean simulation based on the paper by Jerry Tessendorf. - GitHub - klantz81/ocean-simulation: An ocean simulation based on the paper by Jerry Tessendorf.AbstractThe role of virtual environments (VEs) is crucial in efficient design and operation of unmanned vehicles.
