RISThe Role of Ekman Ocean Heat Transport in the Northern Hemisphere Response to ENSO
Publisher: American Meteorological Society
Abstract: The influence of oceanic Ekman heat transport (Qek) on air?sea variability associated with ENSO teleconnections is examined via a pair of atmospheric general circulation model (AGCM) experiments. In the mixed layer model ...
Doppler Radar Observations of an Asymmetric Mesoscale Convective System and Associated Vortex Couplet
Publisher: American Meteorological Society
Abstract: A study of the 28 May 1985 ?asymmetric? mesoscale convective system (MCS) observed during PRE-STORM is presented. Dual-Doppler analysis revealed a well-defined cyclonic mesovortex in the northern portion of the stratiform ...
Surface Flux Variability over the North Pacific and North Atlantic Oceans
Publisher: American Meteorological Society
Abstract: Daily fields obtained from a 17-yr atmospheric GCM simulation are used to study the surface sensible and latent heat flux variability and its relationship to the sea level pressure (SLP) field. The fluxes are analyzed over ...
Net Shortwave Fluxes over the Ocean
Publisher: American Meteorological Society
Abstract: Net surface shortwave fluxes (Qsw) computed from National Aeronautics and Space Administration/Langley satellite data are compared with Qsw from reanalyses of the European Centre for Medium-Range Weather Forecasts (ERA) ...
High-Resolution Downscaled Simulations of Warm-Season Extreme Precipitation Events in the Colorado Front Range under Past and Future Climates
Publisher: American Meteorological Society
Abstract: high-resolution case-based approach for dynamically downscaling climate model data is presented. Extreme precipitation events are selected from regional climate model (RCM) simulations of past and future time periods. Each ...
Greenhouse Gas–Induced Changes in Summer Precipitation over Colorado in NARCCAP Regional Climate Models
Publisher: American Meteorological Society
Abstract: recipitation changes between 32-yr periods in the late twentieth and mid-twenty-first centuries are investigated using regional climate model simulations provided by the North American Regional Climate Change Assessment ...
The Late Fall Extratropical Response to ENSO: Sensitivity to Coupling and Convection in the Tropical West Pacific
Publisher: American Meteorological Society
Abstract: The extratropical response to El Niño in late fall departs considerably from the canonical El Niño signal. Observational analysis suggests that this response is modulated by anomalous forcing in the tropical west Pacific ...
Forecasting Pacific SSTs: Linear Inverse Model Predictions of the PDO
Publisher: American Meteorological Society
Abstract: A linear inverse model (LIM) is used to predict Pacific (30°S?60°N) sea surface temperature anomalies (SSTAs), including the Pacific decadal oscillation (PDO). The LIM is derived from the observed simultaneous and lagged ...
The Impact of Extratropical Atmospheric Variability on ENSO: Testing the Seasonal Footprinting Mechanism Using Coupled Model Experiments
Publisher: American Meteorological Society
Abstract: Previous studies suggest that extratropical atmospheric variability influences the tropics via the seasonal footprinting mechanism (SFM), in which fluctuations in the North Pacific Oscillation (NPO) impact the ocean via ...
ENSO’s Impact on the Gap Wind Regions of the Eastern Tropical Pacific Ocean
Publisher: American Meteorological Society
Abstract: he recently released NCEP Climate Forecast System Reanalysis (CFSR) is used to examine the response to ENSO in the northeast tropical Pacific Ocean (NETP) during 1979?2009. The normally cool Pacific sea surface temperatures ...
