RISA Joint Statistical and Dynamical Assessment of Atmospheric Response to North Pacific Oceanic Variability in CCSM3
Publisher: American Meteorological Society
Abstract: Atmospheric response to North Pacific oceanic variability is assessed in Community Climate System Model, version 3 (CCSM3) using two statistical methods and one dynamical method. All methods identify an equivalent barotropic ...
On the Mechanism of Pacific Multidecadal Climate Variability in CCSM3: The Role of the Subpolar North Pacific Ocean
Publisher: American Meteorological Society
Abstract: Previous analyses of the Community Climate System Model, version 3 (CCSM3) standard integration have revealed pronounced multidecadal variability in the Pacific climate system. The purpose of the present work is to investigate ...
Origin of Pacific Multidecadal Variability in Community Climate System Model, Version 3 (CCSM3): A Combined Statistical and Dynamical Assessment
Publisher: American Meteorological Society
Abstract: Observations indicate that Pacific multidecadal variability (PMV) is a basinwide phenomenon with robust tropical?extratropical linkage, though its genesis remains the topic of much debate. In this study, the PMV in the ...
A GEFA Assessment of Observed Global Ocean Influence on U.S. Precipitation Variability: Attribution to Regional SST Variability Modes
Publisher: American Meteorological Society
Abstract: This paper presents a comprehensive assessment of the observed influence of the global ocean on U.S. precipitation variability using the method of Generalized Equilibrium Feedback Assessment (GEFA), which enables an ...
Rethinking Tropical Ocean Response to Global Warming: The Enhanced Equatorial Warming
Publisher: American Meteorological Society
Abstract: The response of tropical Pacific SST to increased atmospheric CO2 concentration is reexamined with a new focus on the latitudinal SST gradient. Available evidence, mainly from climate models, suggests that an important ...

Predicting US Drought Monitor (USDM) States using Precipitation, Soil Moisture, and Evapotranspiration Anomalies, Part I: Development of a Non-Discrete USDM Index.
Publisher: American Meteorological Society
Abstract: he U.S. Drought Monitor (USDM) classifies drought into five discrete dryness/drought categories based on expert synthesis of numerous data sources. In this study, an empirical methodology is presented for creating a ...
Predicting the US Drought Monitor (USDM) using Precipitation, Soil Moisture, and Evapotranspiration Anomalies, Part II: Intraseasonal Drought Intensification Forecasts.
Publisher: American Meteorological Society
Abstract: robabilistic forecasts of US Drought Monitor (USDM) intensification over two, four and eight week time periods are developed based on recent anomalies in precipitation, evapotranspiration and soil moisture. These statistical ...
Assessing the Evolution of Soil Moisture and Vegetation Conditions during a Flash Drought–Flash Recovery Sequence over the South-Central United States
Publisher: American Meteorological Society
Abstract: AbstractThis study examines the evolution of soil moisture, evapotranspiration, vegetation, and atmospheric conditions during an unusual flash drought?flash recovery sequence that occurred across the south-central United ...
