Effect of Exclusion of Anomalous Tropical Stations on Temperature Trends from a 63-Station Radiosonde Network, and Comparison with Other Analyses
Publisher: American Meteorological Society
Abstract: A 63-station radiosonde network has been used for many years to estimate temperature variations and trends at the surface and in the 850?300-, 300?100-, and 100?50-mb layers of climate zones, both hemispheres, and the ...
Variation with Height and Latitude of Radiosonde Temperature Trends in North America, 1975–94
Publisher: American Meteorological Society
Abstract: Based on the 120-station North American radiosonde network, temperature trends for 100?50-mb (low stratosphere), 300?100-mb (tropopause), and 850?300-mb (troposphere) layers, and Earth?s surface, are evaluated for six 10° ...
Air Motions in the Tropical Stratosphere Deduced from Satellite Tracking of Horizontally Floating Balloons
Publisher: American Meteorological Society
Abstract: Between June and November of 1970, 26 GHOST-type constant-level balloons were released from Ascension Island (8S) for flight at 30 and 50 mb. The balloons were positioned by the Interrogation, Recording and Location System ...
A Comparison of Circulations in Transverse and Longitudinal Planes in an Unstable Planetary Boundary Layer
Publisher: American Meteorological Society
Abstract: Circulations in the vertical-lateral and vertical-longitudinal planes in an unstable planetary boundary layer are compared through the use of tetroon trajectories. On the average, the circulation in the transverse plane ...
Changes in the 300-mb North Circumpolar Vortex, 1963–2001
Publisher: American Meteorological Society
Abstract: The mean monthly polar stereographic map analyses of the Free University of Berlin terminated at the end of 2001. This paper summarizes the changes in size of the 300-mb north circumpolar vortex, and quadrants, for the ...
USE OF TETROONS TO INVESTIGATE THE KINEMATICS AND DYNAMICS OF THE PLANETARY BOUNDARY LAYER
Publisher: American Meteorological Society
Abstract: Discussed is the use of tetroons to obtain estimates of the Reynolds stresses, the rate of production of eddy kinetic energy through these stresses, the coefficient of eddy viscosity, and the viscous dissipation within the ...
METEOROLOGICAL APPLICATIONS OF CONSTANT-PRESSURE BALLOON TRAJECTORIES
Publisher: American Meteorological Society
Abstract: The areal coverage to be expected from 300-millibar constant-pressure balloons (CPB) is examined for various numbers of releases per day from various stations. The meteorological variables which can be measured are discussed. ...
Downward-Propagating Temperature Anomalies in the Preconditioned Polar Stratosphere
Publisher: American Meteorological Society
Abstract: Dynamical links of the Northern Hemisphere stratosphere and troposphere are studied, with an emphasis on whether stratospheric changes have a direct effect on tropospheric weather and climate. In particular, downward ...
Using First Differences to Reduce Inhomogeneity in Radiosonde Temperature Datasets
Publisher: American Meteorological Society
Abstract: The utility of a ?first difference? method for producing temporally homogeneous large-scale mean time series is assessed. Starting with monthly averages, the method involves dropping data around the time of suspected ...
