Abstract: A new concept of a thermally induced local circulation is presented by numerical and observational studies. This wind system transports a low-level air mass from a plain to a basin, passing over a mountain ridge. The ...

Abstract: The thermally induced circulation in a deep valley during fair weather and weak synoptic wind conditions is simulated by a two-dimensional numerical model, in order to investigate the daytime planetary boundary layer ...

Abstract: Nocturnal cooling and daytime heating in a basin were studied on clear and calm days by means of heat budget observations. In the nighttime, drainage flow occurs along the basin sideslope and advects cold air to the boundary ...

Abstract: The ?Hirodo-kaze,? a local strong wind accompanying the downslope winds in Japan, is examined using a mesoscale numerical model. The model successfully reproduces the major features of the observed Hirodo-kaze that occurred ...
