  1. Wave coupling of the lower, middle and upper atmosphere Middle atmosphere variability influences the thermosphere/ionosphere TEC modulation during disturbed middle atmosphere Possible influence through tides and planetary waves Role of gravity waves Use a middle and upper atmosphere model

  2. PW coupling trough modulation of GW Contours: zonal mean wind Greyscaling: potential energy from SABER temperature profiles Dashed line: TID proxy over Europe Solid line: PWTO proxy form TEC maps

  3. Collm MLT winds and temperatures winter 2008/2009

  4. MUAM model no travelling PW zonal mean lower stratospheric temperatures nudged

  5. Proposed work • Modellingresponseofthemiddleatmosphereandthermosphereto SSW • simple andcosteffective model • GW parameterizationforthethermosphererequired • Analysis of wind wind, temperatureandtidalresponse • Possibleroleof GW, tides… • Analysis ofSwarmdata on smallscales • Small scalevariabilty in densities, electroncontent
