This study investigates changes in temporal trends and spatial patterns of precipitation in Beijing over the last six decades. These changes are discussed in the context of rapid urbanization and the growing imbalance between water supply and demand in Beijing. We observed significant decreases in precipitation amounts from 1950 to 2012, with the annual precipitation decreasing by 32% at a deca...

of a dissertation at the University of Miami. Dissertation supervised by Professor Brian Soden. No. of pages in text. (118) Simulating and understanding the anthropogenic changes in atmospheric circulation and precipitation is a great challenge in climate change studies. Current climate projections rely primarily on coupled atmosphere-ocean models (CGCMs). Due to limited computational resources...

The long-standing mainstay of support for C. T. R. Wilson’s global circuit hypothesis is the similarity between the diurnal variation of thunderstorm days in universal time and the Carnegie curve of electrical potential gradient. This rough agreement has sustained the widespread view that thunderstorms are the ‘‘batteries’’ for the global electrical circuit. This study utilizes 10 years of Trop...

An archive of land-based, surface-observed cloud reports has been updated and now spans 39 years from 1971 through 2009. Cloud-type information at weather stations is available in individual reports or in long-term, seasonal, and monthly averages. A shift to a new data source and the automation of cloud reporting in some countries has reduced the number of available stations; however this datas...

The impact of interannual variability of precipitation and potential evaporation on the long-term mean annual evapotranspiration as well as on the interannual variability of evapotranspiration is studied using a stochastic soil moisture model within the Budyko framework. Results indicate that given the same long-term mean annual precipitation and potential evaporation, including interannual var...

■ Abstract The influence of surface orography on patterns of precipitation gives rise to some of the most pronounced climate gradients on Earth, and plays a fundamental role in the interaction between the atmosphere and the rest of the Earth System on a wide variety of time scales. The physical mechanisms involved comprise a rich set of interactions encompassing fluid dynamics, thermodynamics, ...

The climatic effects of dust aerosols in North Africa have been investigated using the atmospheric general circulation model (AGCM) developed at the University of California, Los Angeles (UCLA). The model includes an efficient and physically based radiation parameterization scheme developed specifically for application to clouds and aerosols. Parameterization of the effective ice particle size ...

The article discusses a linguistic analysis of one the main fragments meteorological vocabulary modern Russian language – names atmospheric precipitation. material for study was units lexical-semantic group "precipitation", previously identified in Hydrometeorological Encyclopedia (2009). Three groups nouns were distinguished: common word precipitation itself and its synonym hydrometeors, liqui...
