Journal ArticleDOI
The relationship between surface-renewal and bursting motions in an open-channel flow
TL;DR: In this article, a mass-transport experiment with methylene-blue tracer was performed to estimate the frequency of surface renewal and bursting in an open-channel flow with a laser-Doppler velocimeter at a position in the buffer region.
Journal ArticleDOI
Turbulence structure in stably stratified open-channel flow
TL;DR: In this article, the effects of stable stratification on turbulence structure have been experimentally investigated in stratified open-channel flow and a theoretical spectral-equation model has been applied to the stably stratified flow.
Journal ArticleDOI
Photochemical formation of particulate dicarboxylic acids under long-range transport in central Japan
TL;DR: In this article, the behavior of dicarboxylic acids in the airborne aerosols was investigated in the cooperative field observation of meteorology and chemistry and it was concluded that more than 70% of the DBA were produced by photochemical reactions in the daytime.
Journal ArticleDOI
Numerical modeling of the nocturnal urban boundary layer
TL;DR: In this article, a numerical case study with a second-order turbulence closure model is proposed to study the role of urban canopy layer (UCL) for the formation of the nocturnal urban boundary layer.
Journal ArticleDOI
An observational study of the structure of the nocturnal urban boundary layer
TL;DR: The formation mechanism of the nocturnal urban boundary layer (UBL), especially in the winter nighttime, was investigated based on the extensive field observations conducted during November 1984 in Sapporo, Japan as discussed by the authors.
