| Zusammenfassung |
| Typical events of torques exerted by the Alps are analysed by correlating
flow observations in the Mediterranean with these torques. More
specifically, events with positive torques with respect to the "rotation
axis" at 90° E, 0° N in fall are selected. A trough forms above the
western Mediterranean during such an event with a ridge in the west. A
separate low pressure system is induced in the lee of the Alps which moves
then eastward with the upper-level trough. A linear forecast equation based
on potential temperature changes reveals that this Alpine "lee cyclone" is
mainly due to warm air advection east of the trough. Precipitation is
discussed as well. |
