Abstract: Air pollution characteristics over the Kathmandu Valley in wintertime were numerically investigated by using a comprehensive transport?chemistry?deposition model of air pollutants together with the fifth-generation ...

Abstract: Air pollution transport in the Kathmandu valley/basin has been investigated by numerical simulation of local flows and the observation of NO2 and SO2. The observation was performed at 22 sites with passive samplers from ...

Abstract: Air pollution in the presence of two types of local flows (i.e., land/sea breeze and mountain/valley wind) was studied by advection simulation of the cluster of hypothetical fluid particles, and transport/chemistry calculation ...

Abstract: Influence of both urbanization in modified land use in a plain area, the Nohbi Plain of central Japan, and surrounding large-scale topography, such as the Japanese Alps, on the temperature and local wind over the plain has ...

Abstract: epal has been the location of a series of fatal aircraft accidents, raising serious concerns about civil aviation security and the safety of passengers. However, significant studies on weather patterns associated with the ...

Abstract: The characteristics of the transport of chemically reactive species under land- and sea-breeze (LSB) circulations are investigated using a detailed transport/chemistry model, which includes 84 gas-phase and 10 heterogeneous ...
