Abstract
Disturbances of the airflow originating from small-scale mountains where the hydrostatic relation does not hold good, are here discussed. Numerical experiments are carried out on the airflow over mountains with a two-layer model corresponding to the observed clouds over Mt. Fuji. The lee-wave cloud, hydraulic jump cloud and banner cloud over Mt. Fuji are dynamically studied, taking the effects of heating and cooling from the surface ground into account.
