✦ Synopsis

The integral model for katabatic flows proposed by Manins and Sawford (1979) is solved numerically. It is shown that numerical solutions can be approximated by Ball's (1956) model in the upper part of the slope, while they tend toward Manins and Sawford's simplified solution farther downslope. The importance of entrainment and ambiant stable stratification is shown. Some limitations of Manins and Sawford's model are discussed.

## Abstract Katabatic flow down long glaciers in high latitudes experiences deflection due to the Coriolis force. If the Coriolis force is added to the classic Prandtl model for katabatic flow, the cross‐slope wind component does not approach a true steady state, but rather diffuses upwards in time
