The character of the atmospheric general circulation during summer-season droughts over Eastern Europe/Western Russia and North America late twentieth early twenty first century is examined here. A criterion to examine drought events that encompassed summer season (an important part growing season) was used determine which years were driest, using precipitation, evaporation, areal coverage. rel...
Extreme weather events, particularly floods and heat waves, annually affect millions of people and cause billions of dollars of damage. In 2003, in Europe, Canada, and the United States, floods and storms caused 15 deaths and US$2.97 billion in total damages, and the extended heat wave in Europe caused more than 20,000 excess deaths (1); the impacts in developing countries were substantially la...
A common assumption in frequency analysis is that hydrologic extremes ( oods or heavy precipitation) are generated by a random process. This implies that natural climatic variability does not change the distribution of extreme events. A regional frequency analysis approach is proposed to test the hypothesis of randomness over secular time scales. Observed regional occurrences of extreme events ...
tally a climatic and oceanographic phenomenon, but it has profound effects on terrestrial ecosystems as well. Although the ecological effects of ENSO are becoming increasingly known from a wide range of terrestrial ecosystems (Holmgren et al. 2001; Wright 2005), their impacts have been most intensively studied in arid and semiarid systems. Because inter-annual variability in precipitation is su...

introduction: over the past hundred years, human activity has significantly altered the atmosphere and increase of concentration of greenhouse gases lead to warm the earth's surface. this global warming leads to change of climatic extreme index and increases the intensity and frequency of occurrence of extreme climate events. investigation of extreme values for planning and policy for the agric...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
