Abstract
Cloud bands observed over the Arctic sea ice are interpreted in terms of long-wavelength gravity-wave modes trapped between the ground and a vertically-thin over-reflecting layer in the mid-troposphere. The over-reflecting layer is neutrally-stratified and lies between the counter-streaming upper troposphere and lower troposphere in a strong high-pressure system. The Arctic cloud bands appear to share many features with the long-wavelength roll waves observed in more temperate latitudes.
