Atmospheric Kármán Vortex Shedding from Jeju Island, East China Sea: A Numerical Study
Publisher: American Meteorological Society
Abstract: mesoscale atmospheric numerical model is used to simulate two cases of Kármán vortex shedding in the lee of Jeju Island, South Korea, in the winter of 2013. Observed cloud patterns associated with the Kármán vortex shedding ...
Formation Mechanism of Dust Devil–Like Vortices in Idealized Convective Mixed Layers
Publisher: American Meteorological Society
Abstract: ust devils are small-scale vertical vortices often observed over deserts or bare land during the daytime under fair weather conditions. Previous numerical studies have demonstrated that dust devil?like vertical vortices ...
A Numerical Study of “Hijikawa-Arashi”: A Thermally Driven Gap Wind Visualized by Nocturnal Fog
Publisher: American Meteorological Society
Abstract: AbstractA renowned local wind in Japan, ?Hijikawa-Arashi,? is a thermally driven nocturnal gap wind accompanied by fog. The wind is visually identified by the fog along the valley of the Hijikawa River between the Ozu basin ...
Idealized high-resolution simulations of a back-building convective system that causes torrential rain
Publisher: American Meteorological Society
Abstract: Record-breaking precipitation due to a back-building convective system occurred in Kyushu Island, Japan, on 5 July 2017. In this paper, a quasi-stationary back-building convective system is reproduced using a regional ...
Large-Eddy Simulation of a Residual Layer: Low-Level Jet, Convective Rolls, and Kelvin–Helmholtz Instability
Publisher: American Meteorological Society
Abstract: iurnal variations of an atmospheric boundary layer from 0900 LST on day 33 to 0600 LST on day 34 of the Wangara experiment are studied using a large-eddy simulation (LES) model that includes longwave radiation and ...
