NUMERICAL SIMULATION OF SEA BREEZES OVER THE AUCKLAND REGION, NEW ZEALAND - AIR QUALITY IMPLICATIONS

摘要: The air pollution meteorology of a typical sea breeze day is investigated using the Colorado State University Mcsoscale Model. Results are qualitatively compared with observations and reveal complex wind field characterised by migratory convergence zones. Associated these features, model predicts enhanced upward vertical velocities ‘doming’ planetary boundary layer (PBL). diurnal variation in PBL depth shown to vary markedly at different locations dependent on position relation These spatial temporal variations have important implications for quality Auckland confirm that simple Gaussian or box trajectory approaches inappropriate assessment such environments. inclusion variable surface properties, dynamic synoptic state improved parameterisations, as well coupling Lagrangian particle model, recommended if be used tool further studies area.
