foehn phase

foehn phase

[′fān ‚fāz]
(meteorology)
One of three stages to describe the development of the foehn in the Alps: the preliminary phase, when cold air at the surface is separated from warm dry air aloft by a subsidence inversion; the anticyclonic phase, when the warm air reaches a station as the result of the cold air flowing out from the plain; and the stationary phase or cyclonic phase, when the foehn wall forms and the downslope wind becomes appreciable.

Reportedly, this is the time when the first intense foehn phase occurred.
The reported intense foehn phases are generally reproduced with a lag of [+ or -] 1-3 h in the DEM (same lags in #27 and #51), but the simulation does not clearly indicate that the winds were stronger (weaker) at Zurich (Glarus) at noon compared to the early morning hours (not shown).
