Tropical Pacific Sea Level Variations (1948–98)

Tropical Pacific Sea-Surface Temperatures and Preceding Sea Level Pressure Anomalies in the Subtropical North Pacific

Future extreme sea level seesaws in the tropical Pacific.

Global mean sea levels are projected to gradually rise in response to greenhouse warming. However, on shorter time scales, modes of natural climate variability in the Pacific, such as the El Niño-Southern Oscillation (ENSO), can affect regional sea level variability and extremes, with considerable impacts on coastal ecosystems and island nations. How these shorter-term sea level fluctuations wi...

Sea-level rise at tropical Pacific and Indian Ocean islands

Historical and projected sea-levels for islands in the tropical Pacific and Indian oceans are a subject of considerable interest and some controversy. The large variability (e.g. El Niño) signals and the shortness of many of the individual tide-gauge records contribute to uncertainty of historical rates of sea-level rise. Here, we determine rates of sea-level rise from tide gauges in the region...

Sea level variability in the eastern tropical Pacific as observed by TOPEX and Tropical OceanGlobal Atmosphere Tropical AtmosphereOcean Experiment

Sea surface height measurements from the TOPEX altimeter and dynamic height from Tropical Ocean-Global Atmosphere Tropical Atmosphere-Ocean (TOGA TAO) moorings are used to explore sea level variability in the northeastern tropical Pacific Ocean. After the annual harmonic is removed, there are two distinct bands of variability: one band is centered at 5øN to 7øN and extends from 165øW to 110øW, ...

Sea level from temperature profiles in the tropical Pacific Ocean, 19751982

We investigate how well the 1975-1992 sea level interannual variability in the tropical Pacific is captured by dynamic height from temperature profiles. For each temperature profile, a surface dynamic height relative to 300 m is estimated, assuming a constant temperature-salinity relationship. After multiplication by a latitudinally varying factor and the removal of a seasonal cycle, the dynami...
