On Breezes along a Mountain Slope

Abstract

The author makes a study of the breezes along a mountain slope in a similar way to what was adopted in his previous paper on “Land and Sea Breezes.” In the circulation due to heat in such low layers, the surface friction seems to play its part remarkably. The calculated values of the wind velocity seem to be consistent with the observed ones, if an appropriate value of the frictional coefficient is taken. It is also concluded that the level of the counter-current goes up higher, as the angle of inclination becomes smaller, which the wind velocity near the surface does not make a great change. Finally, the author suggests a season why the average wind vector revolves daily at an observing station situated in the inland plain.
