LONG-TERM VARIABILITY OF PRECIPITATION AND AIR TEMPERATURE IN CRISURI AND ARAD PLAINS
Journal Title: Natural Resources and Sustainable Development - Year 2013, Vol 3, Issue 1
Abstract
To show the secular fluctuations of precipitation and air temperature across the plains between the rivers Barcău and Mureş, we used the annual amounts of precipitation and annual average values of air temperature from weather stations which had the longest row of observation, on their operation period: Arad, during 1880-2012 (133 years) and Oradea, during 1901-2012 (112 years). So, the years as well as the rainy/dry, respectively the hot/cold decades were revealed. We pointed out what was the linear tendency of annual precipitation amounts and average annual temperatures during the secular period. The result was that the drought of the year 2000 exceeded that of the years 1946-1947. The driest year was 2000, and the wettest years were 1941 and 1889. The warmest year was 1934 and the coldest year was 1940. In Arad, during the secular period, precipitation decreased, while in Oradea they remained constant. The temperature remained constant in Arad, and in Oradea there was a very slight increase. The driest decade recorded at Arad station was 1921-1930, followed by 1941-1950 and the wettest decade was 1881-1890. The warmest decade in the plains was 2000-2009, followed by 1943-1952. The last years of the analyzed period, hot, were compared to some cold years (the period 1961-1990 or 1951-1990), and not th
