Hall, C.M., Aso, T., Manson, A.H., Meek, C.E., Nozawa, S. and Tsutsumi, M. (2003). High-latitude mesospheric mean winds: A comparison between Tromsø (69°N) and Svalbard (78°N). Journal of Geophysical Research 108: doi: 10.1029/2003JD003509. issn: 0148-0227.

Daily mean winds in the upper mesosphere regions above Troms¿ (69¿N, 19¿E) and Svalbard (78¿N, 16¿E) are presented; these having been obtained from 6 years' operation of the middle frequency radar at Troms¿ and almost 2 years' operation of the Svalbard meteor radar. The findings depart somewhat from the predictions of current modeling, particularly in that outflow from the pole occurs almost all year-round. This picture is in accordance with a Ferrell cell circulation in summer but not in winter. Gravity-wave drag, parameterized by the Rayleigh drag coefficient, is suggested as a likely cause of the widespread ageostrophic motion characterizing the winter dynamics.
