Computational fluid dynamics was employed to predict the early stages of aerodynamic breakup a cylindrical water column, due impact traveling plane shock wave. The unsteady Reynolds-averaged Navier–Stokes approach used simulate mean turbulent flow in virtual tube device. compressible governing equations were solved by means finite volume-based numerical method, where volume technique track air–...

[1] The role of low-level transpacific paths in bringing east Asian air to the North American west coast surface is determined using conditional transit-time distributions. These distributions are computed with the MATCH transport model driven by NCEP reanalysis data. Transpacific paths that lie entirely below 2.2 km contribute negligibly to the west coast column burden of east Asian air. Howev...

Net vertical air mass export by thermally driven flows from the atmospheric boundary layer (ABL) to the free troposphere (FT) above deep Alpine valleys was investigated. The vertical export of pollutants above mountainous terrain is presently poorly represented in global chemistry transport models (GCTMs) and needs to be quantified. Air mass budgets were calculated using aircraft observations o...
