Colloquium 4/14: Dr. Lynn Greenleaf on “Estimation and Analysis of Atmospheric Vortices”
On Monday April 14th at 3:30 in Math 357, Dr. Lynn Greenleaf will be talking about “Estimation and Analysis of Atmospheric Vortices”.
Abstract: Intense atmospheric vortices occur in dust devils, waterspouts, tornadoes, mesocyclones and tropical cyclones. Tangential wind models have been proposed that approximate the observed tangential wind profile of at atmospheric vortex for the purpose of data analysis and prediction. Data analysis is required to demonstrate in an objective way that a parameterized tangential wind model provides an acceptable description of the tangential wind profile of an atmospheric vortex and determine if the model can be used to make accurate predictions. Using the methodology of Information Theory and Sensitivity Analysis, information content of the parameters of a vortex model show that both parameters are essential in estimation of the tangential wind profile. Uncertainty in radial, tangential and vertical winds were examined and can be used effectively to predict these quantities and their uncertainties. (flyer in PDF form)
