RAS Meeting: Dynamic coupling in the terrestrial atmosphere

A RAS Specialist Discussion Meeting is to be held at Burlington House on Friday 8 December. The meeting is being convened in conjunction with the Royal Meteorological Society, and is convened by Tracy Moffat-Griffin and Andrew Kavanagh (BAS); Nick Mitchell (Bath); and Alan Gadian (Leeds).

It is becoming increasingly apparent that the lower, middle and upper atmosphere are more strongly coupled than was once thought to be the case and that atmospheric waves play a central role in this coupling. Generated by a variety of sources, these waves carry energy and momentum vertically, and are a principle driver of atmospheric circulation, transporting important chemical species through the atmosphere. In the lower atmosphere global scale waves (tides and planetary waves) are generated; smaller scale waves (such as gravity waves) are generated by weather systems, topographic flow and the polar vortex as well as by processes in the upper atmosphere (via space weather effects). There is growing evidence that space weather can have an effect on surface conditions in the Polar Regions yet the coupling mechanism is not fully understood. This meeting aims to bring together the lower, middle and upper atmosphere communities to explore these coupling effects and their impact on global circulation.
