Low latitude ice cores record Pacific sea surface temperatures

Low latitude ice cores record Pacific sea surface temperatures

[1] Oxygen isotope variations in ice cores from Bolivia and Peru are highly correlated with sea surface temperatures (SSTs) across the equatorial Pacific Ocean, which are closely linked to ENSO variability. Circulation anomalies associated with this variability control moisture flux from the equatorial and tropical Atlantic Ocean and Amazon Basin to the ice core sites. Below average SSTs lead t...

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

The Correlation between U.S. Tornadoes and Pacific Sea Surface Temperatures

The correlation between tornadic activity in several regions of the United States and the monthly mean sea surface temperature over four zones in the tropical Pacific Ocean is examined. Tornadic activity is gauged with two mostly independent measures: the number of tornadoes per month, and the number of tornadic days per month. Within the assumptions set forth for the analysis, it is found that...

Neural network forecasts of the tropical Pacific sea surface temperatures

A nonlinear forecast system for the sea surface temperature (SST) anomalies over the whole tropical Pacific has been developed using a multi-layer perceptron neural network approach, where sea level pressure and SST anomalies were used as predictors to predict the five leading SST principal components at lead times from 3 to 15 months. Relative to the linear regression (LR) models, the nonlinea...

The coral record of last interglacial sea levels and sea surface temperatures

Ž . Ž . The rise and fall of the Last Interglacial LI sea levels and sea surface temperatures SSTs are evaluated using U-series dating combined with SrrCa ratios in corals from both stable and tectonically uplifted sites. Along the stable coastal margin of Western Australia, an extensive series of LI coral reefs occur at heights of 2–3 m above present-day sea level. These corals have a very tig...
