Tritium injection and concentration distribution in the atmosphere

摘要: The use of environmental tritium as a water tracer has significantly increased our understanding hydrological processes. Because the large stratospheric reservoir produced by nuclear detonations and relatively slow mixing rates between stratosphere troposphere, studies meteorological parameters transport diffusion can be made over many years. If test ban treaty is observed if no more atmospheric are conducted, seasonal annual changes in distribution give important information on cycle effects. This paper relates injection for to concentration precipitation means parameters. A simplified model been developed that injection, exchange, evaporation, condensation vapor, troposphere.
