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 ...
Assessment of Charge-Air Cooler Health in Diesel Engines Using Nonlinear Time Series Analysis of Intake Manifold Temperature
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Degradation in the cooling effectiveness of a charge-air cooler (CAC) in a medium-duty turbocharged diesel engine has significant impact on engine performance. This degradation lowers the boost ...
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 ...
