Abstract:
Second order modeling of the atmospheric surface mixed layer with stable or unstable stratification, wind shear and yaw and passive pollutants has been remarkable successful. This report presents a second-order model for the motion of atmospheric aerosol particles. Third moment terms are constructed from first principles and contain no new adjustable constants; models for drift terms and particle flux relaxation terms are constructed from realizability considerations, and have general validity. The results compare favorably with Csanady's simple model for the crossing-trajectories effect of Yudine when the particles are passive. It is suggested how the dynamical effect of the particles on the turbulence may be included.
