 cal weather prediction - Budd\, C (University of Bath)

DESCRIPTION:Moving mesh methods can be very effective for problems with ma
 ny scales  such as those which arise in numerical weather prediction and d
 ata assimilation. However traditional moving mesh methods can have problem
 s with implementation and mesh tangling which have made them less effectiv
 e than other adaptive methods for problems in meteorology. In this talk I 
 will describe a moving mesh method based on ideas in the theory of optimal
  transport which derives a mesh by solving a Monge-Ampere equation. This c
 an then be coupled to a CFD solver to provide an effective method for solv
 ing multiscale incompressible flows. I will describe the method and apply 
 it to several meteorological problems.\n\nJoint work with mike Cullen \, c
