| Summary: | <p align="justify">Variation of Ekman pumping in Equatorial Pacific has been studied using surface wind velocity from NCEP/NCAR (National Centers for Environmental Prediction/National Centers for Atmospheric Research). It’s also used temperature from NOAA (National Oceanic and Atmospheric Administration) and ONI (Ocean Nino Index) in the period of 1996 – 2015 (20 years). <br />

Data processing result show that Ekman pumping in the Equatorial Pacific (0.5°N – 0.5°S and 170°E – 110°W) varies by seasonal and interannual (El Niño and La Niña). The mean Ekman pumping has positive value between July to December with the intensity varies between 4.4x10-7 – 1.3x10-6 m s-1, corresponding with SST (Sea Surface Temperature) in the north and cause negative value in south. During El Niño and La Niña evidences, there is a time lag of one to three months between Ekman Pumping and SST anomalies. When trade wind becomes stronger, Ekman Pumping become stronger and there is a time lag of one to two months with zonal wind.<p align="justify"> |
