The impact of flow constraints on extreme events in regional and global climate models

This project investigates the impact of nudging technologies used for
regional climate models on extreme events. The research involves
idealized simulations of the CCCma climate model employing various
nudging methods designed to constrain the solution to follow
reanalysis data or a preexisting climate simulation. In particular,
the influence of the nudging on the the representation of extreme
events is investigated. While this investigation is idealized and is
undertaken with a global climate model, the motivation is a better
understanding of the artifacts of nudging technologies currently
employed by regional climate models to constrain their solutions to
follow driving data in the interior of their domains.
