Stably Stratified Flows: Flow and Dispersion Over Topography : Based on the Proceedings of the Fourth Conference on Stably Stratified Flows, Organized by the Institute of Mathematics and Its Applications and Held at the University of Surrey in September, 1992I. P. Castro, N. J. Rockliff, Institute of Mathematics and Its Applications The first papers of this conference addressed the long-standing issues of the nature of the upstream effects that occur in stratified flow over obstacles (P G Baines, CSIRO, Australia, A P Taylor, York University, Ontario, Canada; K W Ayotte, Boulder, Colorado, USA). Then followed a sessionon internal wave motions followed by a session on modelling the atmospheric boundary layer (J C King, British Antarctic Survey, Cambridge; A Kay, Loughborogh University of Technology). There was a session on numerical modelling (O Matais, Instite de Mecanique de Grenoble, France; A S Smedman,Uppsala University). The various aspects of dispersion were discussed and the final papers in the conference described laboratory experiments on flow and dispersion around buildings in light wind conditions. |
