Canada has undertaken long-term research program to study winter storms in coastal regions, with the objectives of improving their forecast and understanding their embedded mesoscale features, rapid intensification, and microphysical conditions associated with aircraft icing. In cooperation with the Atmospheric Environment Service of Environment Canada (AES), the National Research Council (NRC) Twin Otter and Convair 580 aircraft have been instrumented to measure the motion and thermal structure of the atmosphere and the microphysics of cloud and precipitation. The aircraft have been flown in two Atlantic Storms projects in conditions that pilots usually attempt to avoid. Examples of the hazardous conditions encountered in these research flights are presented in this paper, along with supporting air motion and microphysics data recorded aboard the aircraft. Incidents of airframe icing, turbulence, strong winds and wind shear serve as an introduction to the more detailed treatment of these subjects by subsequent lecturers. Other related subjects covered include research reduced visibility and on-ground icing of aircraft. Information is presented on recent developments in instrumentation for the early recognition and warning of hazardous flight conditions. The paper concludes with a look to the future for coping with winter storms in Canada, including planned research field programs.
