ABSTRACT Midlevel ventilation, or the flux of low-entropy air into the inner(More)
The Department of Earth, Atmospheric, and Planetary Sciences (EAPS) has broad intellectual horizons encompassing the solid Earth, its fluid envelopes, and its diverse neighbors throughout the solar system and beyond. The Department seeks to understand fundamental processes that define the origin, evolution, and current state of these systems and to use this(More)
The sensitivity of tropical cyclone intensity to ventilation of cooler, drier air into the inner core is examined using an axisymmetric tropical cyclone model with parameterized ventilation. Sufficiently strong ventilation induces cooling of the upper-level warm core, a shift in the secondary circulation radially outward, and a decrease in the simulated(More)
The ventilation index serves as a theoretically based metric to assess possible changes in the statistics of tropical cyclones to combined changes in vertical wind shear, midlevel entropy deficit, and potential intensity in climate models. Model output from eight Coupled Model Intercomparison Project 5 models is used to calculate the ventilation index. The(More)

Quantifying and reducing the uncertainty of model parameterizations using observations is evaluated for tropical cyclone (TC) intensity prediction. This is accomplished using a nonlinear inverse modeling technique that produces a joint probability density function (PDF) for a set of parameters. The dependence of estimated parameter values and associated(More)
Lunch immediately following the seminar in FL2-1003. Overview What distinguishes certain clusters of thunderstorms in the tropics, or tropical disturbances, from forming or not forming into hurricanes remains one of the big unsolved problems in tropical meteorology. To address this problem, the Pre-Depression Investigation of Cloud-systems in the Tropics(More)
The 22 May 2014 Duanesburg, New York, supercell produced an enhanced Fujita scale category 3 (EF3) tornado and 10-cm-diameter hail. The synoptic setup for the event was ambiguous compared to other documented cases of Northeast tornadoes. Mesoscale inhomogeneities due to terrain and baroclinic boundaries played a key role in the evolution and severity of the(More)
Overview. The ventilation index derived from the theoretical results of Tang and Emanuel (2010) (hereafter TE10) used an axisymmetric, steady-state, slantwise neutral framework to study the symmetric response of a tropical cyclone (TC) to ventilation. Ventilation is introduced as an eddy flux of entropy through a control surface that surrounds the(More)
