Variability of surface wind in Banda Sea and its correlation with El Nĩo and Southern Oscillation

Abstract

Variability of surface winds in the Banda Sea and its correlation to El Nino and Southern Oscillation (ENSO) have been clearly demonstrated using the European Center for Medium-Range Weather Forecasts (ECMWF) reanalysis data. Surface winds in the Banda Sea are affected by monsoons. When the northwest monsoon, the wind comes from the north and west to the southeast, while the southeast monsoon, the wind comes from the southeast to the northwest. ENSO changes the direction and speed of the wind during the west season, whereas it only changes the speed during the east season.
