PowerPoint Presentation - Ray Tracing of Gravity Waves in Vortex Dipoles

Mesoscale Model and Ray Tracing Model for Dipole Simulation

•A surface dipole

•A mid-level dipole

•A tropopause dipole

•Ro ~ 0.1

•

•Mesoscale Model: MM5 with 2 domains

–Horizontal resolution: 90km and 30km

–Vertical resolution: 180 m

–Dry dynamics, f plane, f=1.0x10-4s-1

–Balanced initiation

•Propagation of gravity waves using ray tracing model: GROGRAT
