Description 1187-1190
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.
