Agroclimatic conditions in Oltenia during the spring of 2011

Abstract: The paper analyses the climatic and agroclimatic conditions during the spring of 2011. Although the climatic global warming process continues, in some years, the climatic evolutions are atypical in Oltenia as well as in the entire country, and, consequently, the spring of 2011 was cold and droughty. Compared to the last 12 springs, the thermal regime indicates that the spring of 2011 was unique, and the pluviometric regime that it was droughty, although the agricultural crops were not affected due to the lower thermal regime that maintained a satisfactory degree of the soil humidity. The late spring hoarfrosts on 7 and 8 May have also had damaging effects in Oltenia. In consequence, there were some stagnation periods for the agricultural crops, and some important delays for the vegetables crops, and there were significant damages in the places where the seedlings were removed in the field. As a consequence of the thermal variations, there have been some diseases and pests, especially Monilinia laxa in stone fruits. Although the periods of weather cooling are considered beneficial to the climate general evolution on the planet, if they appear in the late spring, they represent an important climatic risk factor. Thus, their forecast is welcome especially for the agriculture. This paper is useful for the Ph.D. and master graduates and to all the researchers in the climate and agroclimate field.
