Physical Mechanisms Responsible for the Transition from a Warm to a Cold State of the El Niño–Southern Oscillation
Publisher: American Meteorological Society
Abstract: Based on the switch of a significant sea surface temperature anomaly (SSTA) over the central equatorial Pacific (the Niño-3.4 region) from ≥0.5°C to ??0.5°C, three types of transitions from the warm (El Niño) to the cold ...
A Combined Approach to Improving the Regional Model Forecasts for the Rainy Season in China
Publisher: American Meteorological Society
Abstract: AbstractA combined forecasting methodology, into which the spectral nudging, lateral boundary filtering, and update initial conditions methods are incorporated, was employed in the regional Weather Research and Forecasting ...
An Attempt to Improve the Forecasting of Persistent Severe Rainfall Using the Spectral Nudging and Update Cycle Methods
Publisher: American Meteorological Society
Abstract: sing the interior spectral nudging and update cycle (SN+UIC) methods in the regional Weather Research and Forecasting (WRF) Model, the numerical predictions of four persistent severe rainfall (PSR) events during the preflood ...
The Role of the Asian–Australian Monsoon System in the Onset Time of El Niño Events
Publisher: American Meteorological Society
Abstract: Based on the time of first occurrence of a significant sea surface temperature anomaly (SSTA) in the Niño-3.4 area (5°S?5°N, 170°?120°W), two types of El Niño episodes can be identified: the spring (SP) type in which the ...
Extreme Precipitation Indices over China in CMIP5 Models. Part I: Model Evaluation
Publisher: American Meteorological Society
Abstract: ompared to precipitation extremes calculated from a high-resolution daily observational dataset in China during 1960?2005, simulations in 31 climate models from phase 5 of the Coupled Model Intercomparison Project (CMIP5) ...
S4: An O2R/R2O Infrastructure for Optimizing Satellite Data Utilization in NOAA Numerical Modeling Systems: A Step Toward Bridging the Gap between Research and Operations
Publisher: American Meteorological Society
Abstract: n 2011, the National Oceanic and Atmospheric Administration (NOAA) began a cooperative initiative with the academic community to help address a vexing issue that has long been known as a disconnection between the operational ...
