The local wind field at Ny-Ålesund and the Zeppelin mountain at Svalbard

Using a triaxial Doppler sodar the planetary boundary-layer structure and the wind flow dynamics at the Arctic site Ny-Alesund have been studied. The relationship between winds measured at Ny-Alesund and at the nearby atmospheric research station on Zeppelin mountain was investigated for the first time. While Ny-Alesund receives predominantly katabatic flow (from 120°) from the Kongsvegen glacier, the field is rotated within the lowest 500 m and arrives at Zeppelin from southerly directions.
