Abstract
Possible impacts of the La Nina/Nino Modoki on the precipitation over the maritime continent were investigated in this study. The analysis used the monthly precipitation, sea surface temperature (SST), sea level pressure (SLP), and horizontal wind for a period of January 1948 to December 2013. The results clearly show the change in the distribution of precipitation associated with the La Nina Modoki events. During the dry season from JJA to SON, La Nina Modoki caused annincrease of precipitation almost all over the maritime continent, in particular over the Kalimantam, Sulawesi, Papua, and central/northern part of the Sumatra Islands. The condition continued to the wet season (DJF) although the affected regions were narrower compared to those during the dry season. The enhanced precipitation was related colder SST anomalies in the central Pacific Ocean and warmer SST anomalies in the maritime continent. The warmer SST anomalies in the maritime trggered low-leve wind convergence, increased lower atmospheric water vapour, and enhaced atmospheric convection over the maritime continent that leaded to increase of precipitation. In contrast, El Nino Modoki event caused severe drought in the maritime continent during dry season. The influence of the El Nino Modoki gradually was weaker during the wet season.
