Abstract: Low-frequency signals in the daily variability of temperature in the midtroposphere are investigated, thereby complementing published studies of changes in day-to-day temperature variability and in extreme weather events ...

Abstract: The ocean's angular momentum (M) and torques about the Polar axis are analyzed using output from the global, eddy-resolving model of Semtner and Chervin. Seasonal variability in M is dominated by the annual cycle, whose ...

Abstract: Atmospheric angular momentum (AAM) reached extremely high values during the large 1982?83 El Niño event. The mechanisms responsible for the anomalously high AAM are examined using mountain torque (τm) and friction torque ...

Abstract: Digitized maps of Northern Hemisphere snow cover derived from visible satellite imagery are examined to assess the interannual variability of snow cover in winter months for years 1972?90. The secular trend of winter snow ...

Abstract: Statistics concerning the budgets of angular momentum heat and water vapor over the Northern Hemisphere are computed by two different methods for the winter of 1976?77. The first method employs an objective analysis scheme ...

Abstract: The sensitivity of various zonal mean general circulation statistics to the choice of the averaging period used to define them is tested with upper-air data for the Northern Hemisphere taken from the NMC global analysis ...

Abstract: Modern atmospheric and geodetic datasets have demonstrated that changes in the axial component of the atmosphere's angular momentum and in the rotation rate of the solid earth are closely coupled on time scales of up to ...

Abstract: General circulation fields and statistics are derived for the months of January and July 1983 from different sets of daily global analyses produced by NMC. The two sets differ only in that one has been archived prior to ...

Abstract: Quasi-periodic variations in the relative angular momentum of the atmosphere on time scales of around 40?50 days have been observed by Langley et al. (1981). A description of the two-dimensional (latitude-height) structure ...

Abstract: The simulated North Atlantic Oscillation (NAO) teleconnection patterns and their interannual variability are evaluated from a suite of atmospheric models participating in the second phase of the Atmospheric Model Intercomparison ...
