KARAKTERISTIK SUHU PERMUKAAN LAUT DAN KECEPATAN ANGIN DI PERAIRAN BATAM HUBUNGANNYA DENGAN INDIAN OCEAN DIPOLE (IOD)

Abstract

This study aimed to observe the characteristics of sea surface temperature (SST) and wind velocity and its relation with the Indian Ocean Dipole (IOD) in the waters of Batam. The data used in this study is the SPL and the wind speed in 2016 in the waters of Batam. The method used in this research is the visual analysis using the data ocean view (ODV) to look at the spatial and temporal distribution of the SPL and the wind speed in Batam waters at different seasons. The next method is a fast Fourier transform (FFT). Transitional season one that occurred in April seen the highest wind speed seen with the value of 3.9 m/s^**-1 for components U. As for the V component has the highest value of -3.6 m/s^**-1. Sea surface temperature (SST) Batam highs in April occurred on 19-04-2016 with a value of 304.2°C (31.05°C). West monsoon winds that occurred in January seen the highest wind speed with a value of 4.5 m/s^**-1 for components U. As for the V component has the highest value of 5.2 MS m/s^**-1 in the waters of Batam. . Sea surface temperature (SST) highest Batam in January occurred on 19-01-2016 with a value of 302.8°C (29.65°C). Based on the results of the FFT, wind speed and SPL in the waters of the island has a dominant 6-month period (semiannual).
