Simulation of Atmospheric Variability

Monthly Weather Review, 1981
Abstract A spectral atmospheric circulation model is time-integrated for approximately 18 years. The model has a global computational domain and realistic geography and topography. The model undergoes an annual cycle as daily values of seasonally varying insolation and sea surface temperature are prescribed without any interannual variation.

Variability in Atmospheric Dust Sampling

Transactions of the Kansas Academy of Science (1903-), 1969
Several analyses of variance tests were performed on data obtained from a dust collection network. The results indicate that very careful attention to design of the system, strict control of modifying influences, and close adherence to rigid collection and analytical procedure are necessary for duplicable results to be recorded.

Seasonal and Interannual Variability in the Atmosphere and in the Sea

1994
During the ZISCH project, several cruises were carried out in the period 1986–1989 to investigate concentration and transport of contaminants in the North Sea. Since this transport is also affected by atmospheric fields, wind and temperature fields were determined for a region encompassing the North Sea and the adjoining parts of the Atlantic for the ...

Atmospheric Structure & Variability

1990
Abstract : The contract has supported an extensive programme of atmospheric and ionospheric modelling, aimed at examining Atmospheric Structure and Variability, using the CRAY XMP-48 and the CRAY 2S machines. A technique of forcing tidal and other natural atmospheric fluctuations at the lower boundary of the present version of the 3-dimensional, time ...

Mesoscale Variability of the Atmosphere

1983
Statistical measures of atmospheric variability are reviewed as they apply to the mesoscales. Horizontal spectra of kinetic energy are found to conform approximately to a −5/3 power law from a few to about 1000 km wavelengths, while the vertical spectra follow a slope of about −2.5.

The Variability of Particulate Atmospheres

1990
Inhalation Toxicologists accept that there will be variations in the physical nature of test aerosols which cannot be readily attributed to any single cause. The performance of a chamber suitable for the containment of a particulate atmosphere has been assessed across a range of inlet designs and operating conditions.

Variability of Supergiant Atmospheres

1980
Many if not all supergiants show signs of variability, which is another indication of the instable character of these very extended atmospheres. Most of the variations are of a small amplitude and have a more or less erratic character, but a ‘ characteristic period’ is often detectable.

Atmospheric Circulation and Climatic Variability

2007
Regional variations in South America’s weather and climate reflect the atmospheric circulation over the continent and adjacent oceans, involving mean climatic conditions and regular cycles, as well as their variability on timescales ranging from less than a few months to longer than a year. Rather than surveying mean climatic conditions and variability
