In the last two decades of the 20th century, most meteorological networks replaced traditional mechanical thermometers (usually placed inside a Stevenson screen) with electronic ones (usually in the open air, protected by a plastic shelter). Impacts of such instrumental change on the climatology of daily minimum and daily maximum temperatures are assessed here, by analysing eleven years of data from a couple of stations operating in parallel in the same test site in a location with a Mediterranean climate. Seasonal effects (i.e.

The most significant characteristics of heavy rain cases, plus some strong wind cases, that affected Catalonia, Valencia and the Balearic Islands, as well as some other nearby Spanish regions, during the first experimental campaign (SOP1) of the HyMeX Project are briefly reviewed. Most of these cases correspond to activated intensive observation periods (IOPs) and are documented by an important deployment of extraordinary observation means.

The international HyMeX (Hydrological Mediterranean Experiment) program aims to improve our understanding of the water cycle in the Mediterranean, using a multidisciplinary and multiscale approach and with emphasis on extreme events. This program will improve our understanding and our predictive ability of hydrometeorological hazards including their evolution within the next century. One of the most important results of the program will be its observational campaigns, which will greatly improve the data available, leading to significant scientific results.

This work analyzes the energy teleconnections observed between Sea Surface Temperature anomalies in the North Atlantic and the cyclogenesis of the western Mediterranean basin. The basin has a high edge and in its central part there is a warm and evaporating sea that is crucial for energy exchanges that are key for its autarkic climatology. This could be the reason for not having observed any signification in the teleconnections between Mediterranean rainfalls and the North Atlantic Oscillation index.
