Large-scale circulation associated with westerly wind bursts and deep convection over the western equatorial Pacific

The relationship between deep equatorial convection over the western Pacific and atmospheric circulation during November to February, 1986-1992 is studied using cross correlations between outgoing longwave radiation (OLR) and National Meteorological Center global analyses. The focus is on intraseasonal convective events on the 6- to 30-day timescale over two regions: just east of Borneo and over the Tropical Ocean and Global Atmosphere (TOGA) Coupled Ocean-Atmosphere Response Experiment (COARE) domain to the northeast of New Guinea. The bulk of the intraseasonal variability in both convection and low-level circulation over the tropical western Pacific occurs in this period range. -from Authors
