A SIMULATION OF MONSOONAL CROSS-EQUATORIAL AIR-FLOW BY LAGRANGIAN MODELING

The Australian monsoonal cross-equatorial airflow is simulated in an a ttempt to bridge a highly simplified, while theoretically interesting model to the realities of the actual tropical meteorology. Two factors are found to be essential in the successful simulation of the monsoon al cross-equatorial flow with that model: 1) the existence of a proper ly-positioned quasi-elliptic monsoon depression; 2) sufficient frictio n to force the decay of anticyclonic inertial oscillations and hence t o allow a more 'balanced' type of cyclonic flow around that depression .
