Abstract: In recent years, extreme weather events and climate changes have led to tragic loss of lives and astronomical economical damages around the globe. Accurately predicting these weather and climate events have proven challenging, due to many factors, such as lack of knowledge, lack of data, and models' loss of accuracy over long-term simulations. These are fundamental problems, and successfully addressing them requires an interdisciplinary approach and advances in many related areas, including mathematics, physics, modeling, and computation. This talk documents our recent effort in developing a novel numerical scheme that aims to address some of these challenges. This scheme is remarkable for its general applicability, its comprehensive conservative properties, and its optimal dispersive wave relations, all of which making it a promising candidate for long-term weather and climate applications. Time permitting, preliminary numerical results will be presented.

Title: The derivation of a conservative numerical scheme for large-scale geophysical flows1
Authors: Qingshan Chen
Location: Center for Mathematical Sciences, Room 813
Time: 6:30-9:30pm, Thursday, 2019-6-13

Abstract: In this talk, we will dive into the details of the derivation of the numerical scheme presented in Talk #1. Specifically, we will cover the setup of the numerical framework, the specifications of various differential operators, and the main steps of deriving numerical schemes for Hamiltonian systems. This session is meant as an introduction, for students, into numerical simulation of dynamical systems. Therefore, numerics-related questions are all highly encouraged.
