Compositional Heterogeneity of Hailstones: Atmospheric Conditions and Possible Environmental Implications

Compositional Heterogeneity of Hailstones: Atmospheric Conditions and Possible Environmental Implications

© Royal Swedish Academy of Sciences 2001 Ambio Vol. 30 No. 7, Nov. 2001 http://www.ambio.kva.se Hail is precipitation in the form of balls or irregular chunks of ice, which are usually produced by convective clouds, in association with multicell, supercell, and cold fronts. Hail begins as tiny ice pellets that collide with water droplets. As the attached droplets freeze, the pellets become larg...

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

Dome C atmospheric conditions: implications for astronomy

The expectation that exceptional conditions for astronomy would be found at Dome C on the high Antarctic plateau has motivated a coordinated effort by a number of international teams to comprehensively measure the atmospheric conditions at this site. This paper presents an overview of the current status of site testing at Dome C. We discuss the past, present, and planned instrumentation, the ma...
