Hello everyone, Professor Marek Stastna from University of Waterloo will be visiting the Atmospheric Physics Group at the physics department next week and will be the first of the Atmospheric physics Noble seminar series this year. Professor Stastna's talk will be next Monday (September 19) at 4 pm in Mp609 (see below for more info) and we would like to invite you to attend this seminar. Coffee,tee and cookies will be served on Monday at 3:50 in the coffee/printer room on the sixth floor. Best, Ali Mashayek (on behalf of the Atmospheric Physics Noble Committee) Link to the event page: http://www.physics.utoronto.ca/research/atmospheric-physics/atmosp-monday-seminars/internal-gravity-waves Link to Marek's web page: http://www.math.uwaterloo.ca/~mmstastn/Welcome.html Title and abstract:The benefits of high order methods for simulating internal wave dynamics: from the lake scale to bottom boundary layer interactions The presence of a stable density stratification is the fundamental property of both the atmosphere and natural bodies of water on scales ranging from those associated with small-scale turbulence to those large enough so as to be affected by the Earth's rotation. In this talk I will discuss the numerical simulation of stratified fluid dynamics with a focus on internal wave processes. I will describe the benefits of high-order methods, both for purely numerical simulation and for instances where it is coupled with semi-analytical theory to derive new results. In particular I will discuss fully nonlinear trapped waves over topography, the instability of the bottom boundary layer beneath internal solitary waves and the weakly non-hydrostatic dynamics of small to mid-sized lakes such as those typically found on the Canadian Shield. Throughout, I will introduce the necessary technical vocabulary and will attempt to explain the reasons for the various mathematical developments.
