The 8-hour tide in the Arctic mesosphere and lower thermosphere

An all‐sky VHF meteor radar at Esrange (68°N, 21°E) near Kiruna in Northern Sweden has been used to investigate the 8‐hour tide in the Arctic mesosphere and lower thermosphere. We present a climatology of the 8‐hour tide over the period October 1999 to April 2001. The tide appears to be a persistent...

Description
Summary:An all‐sky VHF meteor radar at Esrange (68°N, 21°E) near Kiruna in Northern Sweden has been used to investigate the 8‐hour tide in the Arctic mesosphere and lower thermosphere. We present a climatology of the 8‐hour tide over the period October 1999 to April 2001. The tide appears to be a persistent feature of the Arctic atmosphere, although a large day‐to‐day variability of the tidal amplitude is observed. At times the 8‐hour tide reaches amplitudes over 30 m s−1. The amplitude of the tide increases with height across the observed height range of ∼80–100 km. Monthly mean tidal amplitudes range from
