Interannual Variability and Predictability of 500 mb Geopotential Heights over the Northern Hemisphere
Publisher: American Meteorological Society
Abstract: The interannual variability of monthly mean 500 mb heights in a 15-year sample of observed data is compared to the variance expected from sampling errors associated with high-frequency fluctuations using the analysis of ...
Variability of Monthly-Averaged Surface and 850 mb Winds at Tropical Pacific Islands
Publisher: American Meteorological Society
Abstract: We examine the variability of monthly mean winds at 850 mb and the surface from five island stations in the tropical western Pacific Ocean. Climatological winds and (850 mb-surface) wind shear are evaluated and used to ...
Autocorrelation of Northern Hemisphere Geopotential Heights
Publisher: American Meteorological Society
Abstract: Local autocorrelation statistics for the Northern Hemisphere geopotential height field are presented for different seasons and tropospheric pressure levels. Values are generally much higher than those calculated from time ...
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 ...
Simulations of the 2004 North American Monsoon: NAMAP2
Publisher: American Meteorological Society
Abstract: The second phase of the North American Monsoon Experiment (NAME) Model Assessment Project (NAMAP2) was carried out to provide a coordinated set of simulations from global and regional models of the 2004 warm season across ...
