Jason Dunion’s presentation at the most recent AMS Hurricane Conference highlighted in the December 2018 issue of the AMS Bulletin

At the recent American Meteorological Society Conference on Hurricanes and Tropical Meteorology, Jason presented his work with co-authors Chris Thorncroft, Chris Velden, and Brian McNoldy about the diurnal cycle of convection in hurricanes.  This cycle is a dramatic outward expansion of clouds that begins moving away from the storm center each day around sunset and … Continue reading Jason Dunion’s presentation at the most recent AMS Hurricane Conference highlighted in the December 2018 issue of the AMS Bulletin

HRD Seminar – Dr. Dave Raymond, New Mexico Institute of Mining and Technology – 12 December 2018

Prof. Raymond presented a seminar titled “Control of Convection in High-Resolution Simulations of Tropical Cyclogenesis”. ABSTRACT: Three idealized high-resolution simulations of tropical storm formation from a weak vortex are analyzed. The three simulations include a case using warm rain microphysics, a case in which surface friction is omitted, and a case in which ice microphysics … Continue reading HRD Seminar – Dr. Dave Raymond, New Mexico Institute of Mining and Technology – 12 December 2018

HRD Seminar – Dr. Yair Cohen, California Institute of Technology – 13 November 2018

Dr. Cohen presented a seminar titled “Gradient Non-Balance: A new approach for the outflow at the top of Tropical Cyclones: Theory, models and observations". ABSTRACT: The gradient non-balance is a flow-regime in which the gradient wind balance has no solutions or a given pressure map. This occurs only around a high pressure center, when the … Continue reading HRD Seminar – Dr. Yair Cohen, California Institute of Technology – 13 November 2018
