The Leading Modes of 10–30 Day Variability in the Extratropics of the Northern Hemisphere during the Cold Season
Publisher: American Meteorological Society
Abstract: The 10?30 day variability of extratropical, cold season (November?March) 700 mb geopotential height data of the Northern Hemisphere was studied through the use of rotated complex principal component (RCPC) analysis. The ...
Some Singularities and Irregularities in the Seasonal Progression of the 700 mb Height Field
Publisher: American Meteorological Society
Abstract: A climatological investigation of singularities in the seasonal progression of 5-day means of 700 mb height was undertaken for the region 30?90°N, from 160°E eastward to 0°, for the period 1947?76. A harmonic analysis was ...
Further Studies of Singularities Associated with the Semiannual Cycle of 700 mb Heights
Publisher: American Meteorological Society
Abstract: An investigation of singularities associated with the semiannual cycle of Northern Hemisphere (25?90°N) 700 mb heights was conducted using 33 years of data. Extension of the harmonic analyses of Lanzante (1983) to a larger ...
A Rotated Eigenanalysis of the Correlation between 700 mb Heights and Sea Surface Temperatures in the Pacific and Atlantic'
Publisher: American Meteorological Society
Abstract: Associations between Pacific and Atlantic sea surface temperature (SST) and the 700 mb circulation were studied using 30 years (1949-78) of gridded monthly data. The monthly data were grouped into four (nonstandard) seasons ...
A Cautionary Note on the Use of Error Bars
Publisher: American Meteorological Society
Abstract: Climate studies often involve comparisons between estimates of some parameter derived from different observed and/or model-generated datasets. It is common practice to present estimates of two or more statistical quantities ...
Diagnosis of Radiosonde Vertical Temperature Trend Profiles: Comparing the Influence of Data Homogenization versus Model Forcings
Publisher: American Meteorological Society
Abstract: Measurements from radiosonde temperatures have been used in studies that seek to identify the human influence on climate. However, such measurements are known to be contaminated by artificial inhomogeneities introduced by ...
Lag Relationships Involving Tropical Sea Surface Temperatures
Publisher: American Meteorological Society
Abstract: A long historical record (?100 years) of monthly sea surface temperature anomalies from the Comprehensive Ocean?Atmosphere Data Set was used to examined the lag relationships between different locations in the global ...
A Further Assessment of the Association between Sea Surface Temperature Gradient and the Overlying Mid-Tropospheric Circulation
Publisher: American Meteorological Society
Abstract: The local association between ocean and atmosphere was examined statistically by correlating the anomalous sea surface temperature (SST) gradient and the anomalous geostrophic wind at the 700 mb level using 30 years (1949?78) ...
