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

Tropical Atmospheric Variability Forced by Oceanic Internal Variability

Journal of Climate, 2007
Abstract Atmospheric general circulation model experiments are conducted to quantify the contribution of internal oceanic variability in the form of tropical instability waves (TIWs) to interannual wind and rainfall variability in the tropical Pacific.

Solar Variability and the Lower Atmosphere

Bulletin of the American Meteorological Society, 1975
Abstract Mechanisms possibly connecting solar activity to meteorology of the lower atmosphere are reviewed. Besides direct variations of solar visible emission, solar-related fluctuations in some aspect of cloudiness could be important. Any such variations in cloudiness are likely to be related to variations in production of ionization near the ...

Atmospheric Variability and Infrasound Monitoring

2009
The propagation of infrasound through the troposphere, stratosphere, and thermosphere is primarily controlled by the thermal structure of the atmosphere, winds, atmospheric attenuation, and reflections from the ground terrain. It is well known that the temperature and circulation of the atmosphere vary continuously, both temporally and spatially, and ...

Seasonal variability of the atmospheric trace constituents in Antarctica

2014 IEEE Geoscience and Remote Sensing Symposium, 2014
This paper investigates the variability of ozone and nitrogen dioxide over the eastern Antarctica. The measurements were made using the MAX-DOAS instrument, which has been developed in NOMREC BSU in 2010. The aim of this work was to test the possibility of retrieval of ozone and nitrogen dioxide in pure Antarctic atmosphere using the MAX-DOAS ...

Atmospheric Variability and Climatic Determinism

Yearbook of the Association of Pacific Coast Geographers, 1968
development. The late William E Petersen characterized the barometric varia bility over the North American continent as the "footprint of As clepius." To him the concentration of the great storm tracks along the northern border of the United States was a portrayal of the areas of maximal meteorological demand on the organism. The chart of a single year

Atmospheric Ozone and Solar Variability

Nature, 1927
IT has been known for a long time that variations in the annual mean values of the daily magnetic range were closely related to variations in the annual sunspot numbers. During recent months a number of other widely different terrestrial phenomena have been found correlated to some extent, at least, with solar changes and with each other.
