| Research Abstract |
This study describes the characteristics of the cross-equatorial northerly surge (CENS) and its relationship to the precipitation patterns over the Maritime Continent. CENS events were classified into the following patterns: CS pattern associated with cold surges over the northern part of the South China Sea, MJO pattern associated with a convectively active phase of the tropical intra-seasonal variations and CS-MJO pattern associated with both cold surges and convectively active tropical intra-seasonal variations. The generation of CENS was an important environmental factor for inducing the wide positive precipitation anomaly compared to the climatological mean over the Maritime Continent.
