Intrinsic Century‐Scale Variability in Tropical Pacific Sea Surface Temperatures and Their Influence on Western US Hydroclimate

نویسندگان

چکیده

Hydroclimate variability of the southwest United States (SWUS) is influenced by tropical Pacific Ocean, particularly through teleconnection to El Niño/Southern Oscillation (ENSO), which expected be altered climate change. Natural in this has not been robustly quantified, complicating detection anthropogenic Here, we use a linear inverse model (LIM) quantify natural ENSO-SWUS teleconnection. The LIM yields realistic patterns with century-scale comparable simulations from Last Millennium Ensemble project and Climate Model Intercomparison Project Phases 5 6. quantified illuminates two aspects our understanding ENSO its impacts: inherent statistics observable system can produce century-long periods wide range correlations SWUS hydroclimate, including nonsignificant correlations, thus that detecting changes ENSO-related hydroclimate challenging changing climate.

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...

Simulated Sea Surface Salinity variability in the tropical Pacific

[1] Sea Surface Salinity (SSS) variability from a hindcast run of an oceanic general circulation model (OGCM) forced by daily NCEP-NCAR reanalysis from 1990 to 2001 is analyzed. The purpose is to test the capability of the model in terms of the salinity simulation and provide insights for the future SSS observation from space. With daily forcing, the model can reproduce SSS change of the tropic...

The Accuracies of Himawari-8 and MTSAT-2 Sea-Surface Temperatures in the Tropical Western Pacific Ocean

Over several decades, improving the accuracy of Sea-Surface Temperatures (SSTs) derived from satellites has been a subject of intense research, and continues to be so. Knowledge of the accuracy of the SSTs is critical for weather and climate predictions, and many research and operational applications. In 2015, the operational Japanese MTSAT-2 geostationary satellite was replaced by the Himawari...
