There is increasing evidence that the globe is currently warming, with changes being more pronounced in northern latitudes. Understanding the ecological effects of climatic variability is therefore important. There is recent support for the idea that a large-scale atmospheric phenomenon, the North Atlantic Oscillation (NAO), through its effects on vegetation and regional weather conditions, inf...

BACKGROUND The amount of carbon dioxide in the atmosphere steadily increases as a consequence of anthropogenic emissions but with large interannual variability caused by the terrestrial biosphere. These variations in the CO2 growth rate are caused by large-scale climate anomalies but the relative contributions of vegetation growth and soil decomposition is uncertain. We use a biogeochemical mod...

Meeting future world energy needs while addressing climate change requires large-scale deployment of low or zero greenhouse gas (GHG) emission technologies such as wind energy. The widespread availability of wind power has fueled substantial interest in this renewable energy source as one of the needed technologies. For very large-scale utilization of this resource, there are however potential ...

Geomorphological indicators of large-scale climatic changes in the Eastern Bolivian lowlands This study provides an inventory of geomorphologi¬ cal landforms in Eastern Bolivia at different spatial scales. Landforms and associated processes are interpreted and discussed regarding landscape evolution and paleoclimatic significance. Thereby. preliminary conclusions about past climate changes and ...

[1] There is an established evidence of climatic teleconnection between El Niño– Southern Oscillation (ENSO) and Indian summer monsoon rainfall (ISMR) during June through September. Against the long-recognized negative correlation between ISMR and ENSO, unusual experiences of some recent years motivate the search for some other causal climatic variable, influencing the rainfall over the Indian ...

The vast availability of wind power has fueled substantial interest in this renewable energy source as a potential near-zero greenhouse gas emission technology for meeting future world energy needs while addressing the climate change issue. However, in order to provide even a fraction of the estimated future energy needs, a large-scale deployment of wind turbines (several million) is required. ...

in this paper, we describe our implementation of an interior point algorithm for large scale systems. first we identify system with small and medium methods convex optimization, then we use interior point method for identification. finally we offer an interior point method that uses nonlinear cost function and see that we achieve a good trade-off between error and cpu time. actually, in this pa...

This chapter gives a brief analysis of basic factors influencing highland climates and peculiarities of atmospheric circulation caused by mountain systems. Special attention is paid to characteristics of highland climate which are manifested in regimes of temperature, precipitation, wind, solar radiation, etc. Typical and exclusive features of highland climates in different large-scale climatic...
