WebAbstract An empirical Rayleigh drag parameterization of the nonhydrostatic mechanisms of precipitation drag and small-scale diabatically induced mixing is introduced into a hydrostatic regional forecast model to curb excessive grid-scale precipitation production. To get the needed damping, the coefficient in the Rayleigh drag is set proportional to the … WebThe drag force is provided by particles in the medium (usually air) buffeting the object-providing a resistive force-providing a slowing down of the motion (drag). If the mass is increased, but the surface area stays the same (so the object is denser, but exactly the same dimensions so gets hit by exactly the same volume of air per second) it will still have the …
