Lessons from a Tropical Cyclone-Permitting AOGCM\n\na talk by\n \nJane Baldwin\n Postdoctoral Research Scientist\n Lamont-Doherty Earth Obse rvatory\, Ocean and Climate Physics\n Columbia University\, Earth Institute \n\nA classic question in atmospheric dynamics is what role mountains play in shaping both local and remote climate. Some of the first studies perfo rmed with Global Climate Models (GCMs) by Syukuro Manabe and colleagues in vestigated this question\, selectively flattening large-scale orographic f eatures (such as the Tibetan Plateau) to investigate effects on the statio nary wave pattern and monsoons. Since these early studies\, GCMs have incr eased significantly in resolution and complexity\, now allowing dynamic co upling between the atmosphere and ocean and simulating various climatic ex tremes with much higher fidelity. Here I revisit the effect of mountains o n climate using the GFDL GCM CM2.5-FLOR\, which is fully atmosphere-ocean coupled with a 50 km atmospheric/land resolution that permits the simulati on of tropical cyclones. I explore the influence of three different orogra phic features on regional climate: 1) the Tian Shan mountains on the clima tology of Asian extratropical deserts\, 2) the Tibetan Plateau (and relate d orography) on the Western North Pacific\, and 3) gaps in the topography of Central America on the tropical East Pacific. Previously unappreciated influences of these mountains on the climatology of precipitation and the spatial distribution of tropical cyclones will be demonstrated. Additional ly\, I will show that relatively small orographic features can have quite large climatic influences contingent on their placement relative to the la rger-scale circulation.\n\nMonday Oct 28/ 3:30 PM/ Burnside Hall/ Room 934 \n DTSTART:20191028T193000Z DTEND:20191028T210000Z LOCATION:Room 934 SUMMARY:What Role Do Mountains Play in Shaping Mean and Extreme Hydroclimat e?
