Large-Amplitude, Short-Scale Stationary Rossby Waves in the Southern Hemisphere: Observations and Mechanistic Experiments to Determine their Origin
Publisher: American Meteorological Society
Abstract: Studies by van Loon and Jenne, van Loon et al., Trenberth and others indicate that stationary waves in the Southern Hemisphere are dominated by planetary scales. Kalnay and Halem reported the presence of large amplitude, ...
Atmospheric Processes Associated with Summer Floods and Droughts in the Central United States
Publisher: American Meteorological Society
Abstract: Persistent wet and dry events over the central United States are examined during summer. Composites based on selected persistent wet and dry events reveal common atmospheric processes and circulation features. During summer, ...
Boundary Layer Control of Nocturnal Convection Associated with a Synoptic Scale System
Publisher: American Meteorological Society
Abstract: A case is presented with pronounced diurnal variations in precipitation and low-level circulations over the Great Plains during 5?10 May 1979. Well-defined nocturnal convection, along with distinct maximum precipitation ...
The South American Low-Level Jet Experiment
Publisher: American Meteorological Society
Abstract: Moisture is transported in South America westward from the tropical Atlantic Ocean to the Amazon basin, and then southward toward the extratropics. A regional intensification of this circulation to the east of the Andes ...
Toward a Unified View of the American Monsoon Systems
Publisher: American Meteorological Society
Abstract: An important goal of the Climate Variability and Predictability (CLIVAR) research on the American monsoon systems is to determine the sources and limits of predictability of warm season precipitation, with emphasis on ...
