Vibrational delocalization in ammonia aerosol particles

Numerical studies for localization-delocalization transition in vibrational spectra

Localization-delocalization transitions in turbophoresis of inertial particles.

Small aerosols drift down a temperature or turbulence gradient since faster particles fly longer distances before equilibration. That fundamental phenomenon, called thermophoresis or turbophoresis, is widely encountered in nature and used in industry. It is universally believed that particles moving down the kinetic energy gradient must concentrate in minima (say, on walls in turbulence). Here,...

Lidar and Atmospheric Aerosol Particles

Wind reduction by aerosol particles

1. Description of the Model The model used for this study was GATOR-GCMOM, a parallelized and one-way-nested global-through-urban scale Gas, Aerosol, Transport, Radiation, General Circulation, Mesoscale, and Ocean Model (S1-S12),. The model treated time-dependent gas, aerosol, cloud, radiative, dynamical, ocean, and transport processes. Aerosol processes were treated among a single aerosol size...
