Here the focus is on understanding orographic precipitation in the tropics over the small island of Dominica. An aircraft dataset from the Dominica Experiment (DOMEX) which took place in the eastern Caribbean is utilized. The aircraft measured upstream and downstream airflow properties as well a s the convective clouds and precipitation over the island. These flight da ta along with an idealized numerical model are used to understand the role of wind speed in controlling the transition from thermally to mechanicall y forced orographic convection.\n\nIn the second part of the presentation\ , the orographic effects of Dominica on Tropical Storm Erika will be explo red. Erika was a weak tropical storm in a sheared environment that passed through the Lesser Antilles on August 27th of 2015. Rain gauges on Dominic a measured almost 20 inches of rain in less than 12 hours. Observations an d a numerical model are used to investigate the tropical storm structure a nd storm environment\, the effect of Dominica's orography\, and other aspe cts that played a role in the heavy precipitation. Results highlight the m ulti-scale interactions that can contribute to heavy precipitation associa ted with tropical cyclone passage near mountainous islands.\n DTSTART:20161007T183000Z DTEND:20161007T193000Z LOCATION:Room 934\, Burnside Hall\, CA\, QC\, Montreal\, H3A 0B9\, 805 rue Sherbrooke Ouest SUMMARY:Seminar: Dr. Alison Nugent URL:/meteo/channels/event/seminar-dr-alison-nugent-263 130 END:VEVENT END:VCALENDAR
