Both help to advect moisture towards convection over the Warm Pool. This zonal structure it will be argued can help explain the observed phasing of convection and dynamics during Westerly Wind Bursts. The vertical structure of surface westerly wind anomalies and the dependence of that vertical structure on horizontal 850mb spatial extent is investigated here. Anomalies during all seasons are considered. The top caption shows the relationship between size and duration of these events.
Smaller events are more numerous but last considerably shorter than their larger counterparts.
The Composite Technique Seven westerly wind bursts are identified during the Northern winter months of November to January, 1985-1993. Thus, a different burst region is chosen for each event. Over each of these regions various paramters will be averaged to show single dimensional temporal trends in the atmosphere, ocean and surface energy balance. Their locations are shown by this map. Dynamics 850mb westerly winds are the identifing feature of the events studied here.
