RISInterdecadal Variation of ENSO Predictability in Multiple Models
Publisher: American Meteorological Society
Abstract: In this study, El Niño?Southern Oscillation (ENSO) retrospective forecasts were performed for the 120 yr from 1881 to 2000 using three realistic models that assimilate the historic dataset of sea surface temperature (SST). ...
Ensemble Construction and Verification of the Probabilistic ENSO Prediction in the LDEO5 Model
Publisher: American Meteorological Society
Abstract: El Niño?Southern Oscillation (ENSO) retrospective ensemble-based probabilistic predictions were performed for the period of 1856?2003 using the Lamont-Doherty Earth Observatory, version 5 (LDEO5), model. To obtain more ...
Improved ENSO Prediction by Singular Vector Analysis in a Hybrid Coupled Model
Publisher: American Meteorological Society
Abstract: In this study, a method based on singular vector analysis is proposed to improve El Niño?Southern Oscillation (ENSO) predictions. Its essential idea is that the initial errors are projected onto their optimal growth patterns, ...
Reduced-Rank Sigma-Point Kalman Filter and Its Application in ENSO Model
Publisher: American Meteorological Society
Abstract: he huge computational expense has been a main challenge while applying the sigma-point unscented Kalman filter (SPUKF) to a high-dimensional system. This study focuses on this issue and presents two methods to construct a ...
Contribution of Changes in Sea Surface Temperature and Aerosol Loading to the Decreasing Precipitation Trend in Southern China
Publisher: American Meteorological Society
Abstract: The effects of increasing sea surface temperature (SST) and aerosol loading in a drought region in Southern China are studied using aerosol optical depth (AOD), low-level cloud cover (LCC), visibility, and precipitation ...
