DIMENSION REDUCTION APPLIED TO A MODEL OF THE SEA BREEZE


ITIR MOGULTAY, PH.D.

When applied to a system of partial differential equations, dimension-reduction techniques produce a new system which is defined over a smaller dimension. The resulting reduced dimension models are easier to compute with and easier to analyze. In this talk, I will present Galerkin reduction, which is one of the dimension reduction techniques, and its application to a model of the sea breeze. A two-dimensional model of the sea breeze is reduced to a system of one-dimensional partial differential equations. The simpler equations of the reduced model give realistic results when compared with observations. I will also discuss stability and convergence results of the reduced system.


Bio:
Itır Moğoltay received her Ph.D. degree in 2003 from the Courant Institute of Mathematical Sciences, New York University. She is presently a visiting scholar at the University of Chicago. Her present research focuses mainly on finding and studying simple models, so called “toy models” for certain physical systems such as fluid flows.
