This meeting is a joint meeting between The Royal Astronomical Society and the Royal Meteorological Society.

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.

This Specialist Discussion Meeting is open to all; admission is free for RAS Fellows & RMetS members (with the provision of a membership card or membership number), £15 for non-Fellows/RMetS members (£5 for full-time students) to be paid in cash at the registration desk.
