The damages from climatic extremes have dramatically increased in the last decades in Europe, as likely outcomes of climate change: floods, droughts, heat waves and hailstorms have brought local as well as widespread damages to farmers, industry, infrastructures and society, to insurance and reinsurance companies; in this work we deal with the hailstorm hazard. The NCEP-NCAR Reanalysis (2.5 by ...

Quantitative information on soil loss is relevant for devising conservation and crop management strategies to ensure sustainable fertility production. Estimations from runoff/erosion plots are expensive laborious thus requiring the exploration of other less but reliable methods such as modeling. This study aimed estimate current future rates planning toward production in semi-deciduous forest z...

The influence of large scale circulation, represented by the first three rotated EOFs and their associated PCs of wintertime mean sea level pressure, on winter maximum daily precipitation over the North America during 1948-1998 has been investigated. The observed relationship between the circulation and the extreme precipitation is then used to derive projected changes in extreme precipitation ...

Black carbon (BC) particles in the atmosphere have important impacts on climate. The amount of BC in the atmosphere must be carefully quantified to allow evaluation of the climate effects of this type of aerosol. In this study, we present the treatment of BC aerosol in the developmental version of the 4th generation Canadian Centre for Climate modelling and analysis (CCCma) atmospheric general ...

Available energy (often expressed in terms of potential evaporation) and precipitation largely determine annual evapotranspiration and runoff rates in a region. The ratio of annual potential evaporation to precipitation, referred to as the aridity index by Budyko, has been shown to describe the evaporation ratio (the ratio of annual evapotranspiration to precipitation) of catchments from a rang...
