Vortex characteristic and impact other than Borneo Vorteks (BV) adequately is of important to be assessed, remembering vorteks's growth region that associate with monsoon trough's region and Mesoscale Convective Vortices (MCV) so to be estimated still available vorteks – vorteks any other that effloresce at Indonesian Maritime Continent (BMI). This vorteks's activity also have siginificance influence in increase and convective decrease at territorial BMI. Study hits characteristic and impact from vorteks what do be assessed by it utilize surface wind data Cross Calibrated Multi is Platform (CCMP ), raining estimation data Tropical Rainfall Measuring Mission (TRMM) period 2005/2006 until 2009/2010 (5 years). vorteks's emergence at BMI was identified to utilize algorithm that merges to assess anomali vortisitas relative and wind vector, where is vortisitas's point relative is accounted from zonal's wind (component u) and meridional (component v). Jakartas flooding case study year 1 2nd February 2007, point out <br /> <br /> <br /> that performa from this method have objective enough in identifies vorteks, sinoptik's trouble at east sectioned Indian Ocean it also give contribution to raining step-up at territorial that, and marks sense meredional's wind step-up north that upright to Javanese region that becomes one of cloud increasing triggers convective at territorial Jakarta. By use of data which longer on period 2005/2006 – 2009/2010 most identification 608 distributed vorteks system at six main regions, East sectioned indian ocean (region I and II.), South China Sea (region III), Javanese south indian ocean (region IV.), Papuan north Pacific ocean (region V) and Arafura's Sea (region VI). From region sixth Indian Ocean above the so called a part east has highest instance frequency and up to maximum on DJF. Aktivitas's period vorteks at east sectioned Indian Ocean on DJF'S period give more influence siginifikan to rain distribution, in comparison with Borneo Vorteks, particularly at the moment happening vorteks who coincides at upstates east Indian Ocean and south (“twin vortices ”).
