Abstract: AbstractThe effects of externally forced tropical sea surface temperature (SST) anomalies on long-term Walker circulation changes are investigated through numerical atmospheric general circulation model (AGCM) experiments. ...
The Role of SST in the East Pacific Warm Pool in the Interannual Variability of Central American Rainfall
Publisher: American Meteorological Society
Abstract: Satellite- and gauge-based precipitation and sea surface temperature (SST) are analyzed to understand the role of SST in the east Pacific warm pool (EPWP) in the interannual variability of Central American rainfall. It is ...
Mechanisms for the Interannual Variability of SST in the East Pacific Warm Pool
Publisher: American Meteorological Society
Abstract: In comparison with the western and equatorial Pacific Ocean, relatively little is known about the east Pacific warm pool (EPWP). Observations indicate that the interannual variability of sea surface temperature (SST) in ...
Strengthening of the Pacific Equatorial Undercurrent in the SODA Reanalysis: Mechanisms, Ocean Dynamics, and Implications
Publisher: American Meteorological Society
Abstract: everal recent studies utilizing global climate models predict that the Pacific Equatorial Undercurrent (EUC) will strengthen over the twenty-first century. Here, historical changes in the tropical Pacific are investigated ...
The Equatorial Undercurrent and TAO Sampling Bias from a Decade at SEA
Publisher: American Meteorological Society
Abstract: he NOAA Tropical Atmosphere Ocean (TAO) moored array has, for three decades, been a valuable resource for monitoring and forecasting El Niño?Southern Oscillation and understanding physical oceanographic as well as coupled ...
The Effect of the Galápagos Islands on ENSO in Forced Ocean and Hybrid Coupled Models
Publisher: American Meteorological Society
Abstract: An ocean general circulation model (OGCM) of the tropical Pacific Ocean is used to examine the effects of the Galápagos Islands on the El Niño?Southern Oscillation (ENSO). First, a series of experiments is conducted using ...
The Effect of the Galápagos Islands on the Equatorial Pacific Cold Tongue
Publisher: American Meteorological Society
Abstract: A reduced-gravity ocean general circulation model of the tropical Pacific Ocean is used to determine potential improvements to the simulated equatorial Pacific cold tongue region through choices in horizontal resolution ...
An Equatorial Ocean Bottleneck in Global Climate Models
Publisher: American Meteorological Society
Abstract: he Equatorial Undercurrent (EUC) is a major component of the tropical Pacific Ocean circulation. EUC velocity in most global climate models is sluggish relative to observations. Insufficient ocean resolution slows the EUC ...
Low-Frequency Variability and Remote Forcing of Gap Winds over the East Pacific Warm Pool
Publisher: American Meteorological Society
Abstract: The low-frequency variability of gap winds at the Isthmuses of Tehuantepec and Papagayo is investigated using a 17-yr wind stress dataset merging the remotely sensed observations of Special Sensor Microwave Imager (SSM/I) ...
