Kejadian upwelling di sepanjang perairan Selatan Nusa Tenggara Timur (NTT) hingga Barat Sumateramerupakan bentuk evolusi upwelling yang setiap tahun berulang. Fenomena upwelling ini dipengaruhioleh musim dan iklim. Adanya perubahan fenomena iklim (Normal, El Niño, dan La Niña) diduga akanmenyebabkan perubahan karakteristik upwelling, baik temporal (periode upwelling), spasial (distribusihorisontal), maupun intensitasnya.
