| Abstract: | Sea level data from four tide gauge stations in the SS (Tanjong Pagar, Sultan Shoal, Sembawang and Raffles Lighthouse) for the period 1970 – 2012 were extracted to study the ENSO-induced interannual sea level variability. Sea level during this period is dominated by inter-annual fluctuations. Monthly sea level anomalies were filtered using a Butterworth low pass filter to obtain inter-annual signals. It is found that at interannual scale, sea level and ENSO index vary coherently in the SS: drops are associated with El Niño phase and rises are related to La Niña episodes. Wind stress variations and reduced SCS volume transport play significant roles in ENSO-induced sea level variability. |
