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