| Abstract: | Summary In this part II of the reanalysis of the global data, we present an interpretation of the transient motion of the winter monsoon over Asia and the India Ocean. This includes an analysis of the surface layer meridional flow channels that are important for the transport of pollutants for the land mass of Asia towards the ITCZ, which is located near 10° S. We have also examined the scales of the space-time variability of the near surface flows of the winter monsoon of the 1992–1993 season. Sample forecasts of these inflow features, using a very high resolution model, are illustrated to show that the field phase of the proposed Indian Ocean Experiment (INDOEX) can receive guidance from real time numerical experimentation. The final part of this paper addresses four dimensional trajectories and passive tracer addresses four dimensional trajectories and passive tracer transports with integration over a winter monsoon domain covering several samples of 10 day periods.With 21 Figures |
