| Zusammenfassung |
| Hofsjökull is a close to circular glacier in the central part of Iceland. The diameter of Hofsjökull is close to 30 km and it rises about 1000 m above its surroundings. During the summer of 2007, observations were made of katabatic flows at the northern edge of Hofsjökull ( FLOHOF - FLow Over and around HOFsjökull). The observations reveal that katabatic winds are quite persistent at the edge of the glacier. However, they extend only a short distance away from the glacier, and at a distance of 7 km from the edge, the katabatic winds are almost non-existent. There is a strong diurnal cycle in the katabatic winds, with a maximum in strength and frequency in the afternoon and a minimum in the early morning. The onset of the katabatic winds is associated with a drop in temperature. |
