The Dynamics of Mountain-Wave-Induced Rotors

摘要: Abstract The development of rotor flow associated with mountain lee waves is investigated through a series high-resolution simulations the nonhydrostatic Coupled Ocean–Atmospheric Mesoscale Prediction System (COAMPS) model using free-slip and no-slip lower boundary conditions. Kinematic considerations suggest that layer separation prerequisite for formation. numerical demonstrate greatly facilitated by adverse pressure gradients trapped processes lee-wave-induced perturbations interact synergistically to produce low-level rotors. Pairs otherwise identical show strong correlation between strength in simulation reversed corresponding simulation. Mechanical shear planetary primary source she...
