RISInvestigation of a Large-Scale Mode of Ocean–Atmosphere Variability and Its Relation to Tropical Pacific Sea Surface Temperature Anomalies
Publisher: American Meteorological Society
Abstract: By examining the linearly coupled atmospheric and oceanic signals related to interannual variability in sea surface temperatures and upper-air wind fields, a hemispheric-scale ocean?atmosphere teleconnection mode is isolated ...
Regional Simulation of Intraseasonal Variations in the Summertime Hydrologic Cycle over the Southwestern United States
Publisher: American Meteorological Society
Abstract: Using results taken from a finescale (25 km) regional modeling simulation for the summer of 1999, intraseasonal variations in the climatological summertime hydrologic cycle over the southwestern United States are described ...
Intraseasonal Atmospheric Variability in the Extratropics and Its Relation to the Onset of Tropical Pacific Sea Surface Temperature Anomalies
Publisher: American Meteorological Society
Abstract: Previous research has shown that seasonal-mean boreal winter variations in the subtropical/extratropical sea level pressure and wind stress fields over the central North Pacific are significantly related to the state of ...
On the Joint Role of Subtropical Atmospheric Variability and Equatorial Subsurface Heat Content Anomalies in Initiating the Onset of ENSO Events
Publisher: American Meteorological Society
Abstract: Previous research has shown that seasonal mean variations in both the subtropical/extratropical sea level pressures over the central North Pacific and the subsurface heat content anomalies in the western equatorial Pacific ...
Interannual Tropical Pacific Sea Surface Temperatures and Their Relation to Preceding Sea Level Pressures in the NCAR CCSM2
Publisher: American Meteorological Society
Abstract: This paper describes aspects of tropical interannual ocean/atmosphere variability in the NCAR Community Climate System Model Version 2.0 (CCSM2). The CCSM2 tropical Pacific Ocean/atmosphere system exhibits much stronger ...
The Diurnal Cycle of the Summertime Atmospheric Hydrologic Cycle over the Southwestern United States
Publisher: American Meteorological Society
Abstract: Diurnal variations in the climatological large-scale summertime hydrologic cycle over the southwestern United States are examined using surface and upper-air observations along with regional model output. Rainfall rates ...
Atmospheric Eddies Mediate Lapse Rate Feedback and Arctic Amplification
Publisher: American Meteorological Society
Abstract: AbstractProjections of amplified climate change in the Arctic are attributed to positive feedbacks associated with the retreat of sea ice and changes in the lapse rate of the polar atmosphere. Here, a set of idealized ...
Characterizing the Potential Predictability of Seasonal, Station-Based Heavy Precipitation Accumulations and Extreme Dry Spell Durations
Publisher: American Meteorological Society
Abstract: he release of seasonal (and longer) predictions of various climatological quantities is now routine. While undoubtedly devastating to lives and livelihoods, it is unclear whether seasonal extremes in precipitation?for ...
Regional Simulation of Summertime Precipitation over the Southwestern United States
Publisher: American Meteorological Society
Abstract: Using results taken from a finescale (25 km), regional modeling simulation for the summer of 1999, along with contemporaneous daily surface observations, synoptic variations in summertime precipitation over the southwestern ...
Identification of Nonlinear Behavior in Transient Climate Change Projections of Soil Moisture over the United States
Publisher: American Meteorological Society
Abstract: While most projections of climate change and its regional impacts focus on overall changes in the state of the climate system, useful information can also be found in the evolution of the climate system from one state to ...
