Economic and social benefits of meteorology and climatology in Switzerland

National Meteorological Services provide meteorological data, information, forecasts and various related products, which are important for the smooth functioning of many aspects in economy, administration and society. The merit of meteorological services cannot be deduced directly from the consumption of services. Rather, it emerges from the improvement of decisions by economic stakeholders tha...

A Fast and Accurate Global Maximum Power Point Tracking Method for Solar Strings under Partial Shading Conditions

This paper presents a model-based approach for the global maximum power point (GMPP) tracking of solar strings under partial shading conditions. In the proposed method, the GMPP voltage is estimated without any need to solve numerically the implicit and nonlinear equations of the photovoltaic (PV) string model. In contrast to the existing methods in which first the locations of all the local pe...

The use of geographical information systems in climatology and meteorology

The proliferation of 'commercial off the shelf' geographical information systems into the scientific community has resulted in the widespread use of spatial climate data in a variety of applications. This paper presents a review of the role of geographical information systems in climatology and meteorology by i) discussing methods used to derive and refine spatial climate data and ii) reviewing...

Recent Climatology, Variability, and Trends in Global Surface Humidity

In situ observations of surface air and dewpoint temperatures and air pressure from over 15 000 weather stations and from ships are used to calculate surface specific (q) and relative (RH) humidity over the globe (60°S–75°N) from December 1975 to spring 2005. Seasonal and interannual variations and linear trends are analyzed in relation to observed surface temperature (T) changes and simulated ...
