ABSTRACT. Consideration on the climatic variability in Oltenia in the autumn of 2013. In the autumn of 2013, in Oltenia, weather evolution has been marked by an exceptional variability with fast transitions from a warm weather to an extremely cold and even excessively cold in some intervals and from an excessively rainy weather to a droughty weather. These fast transitions from one extreme to another of weather aspect are due to the increase of climatic variability, an aspect which is directly connected to climatic global warming. After the warmish summer of 2013, in the end of August, beginning with August 24, a cooling process has begun which has slowly continued during the whole month of September and has strengthened in the last two days. The cooling climax was registered in the interval October 4-5, when negative thermal minimum values were registered, frost in the air and ground and early hoarfrosts which affected crops, especially the vegetable crops. In November the high daily air temperature means led to gradual enforcements, and in the end of the month the autumn crops were in advanced development stages, and in rape the floral stems and studs appeared. The intense weather cooling and snowfalls were registered in the interval November 26-28 2013 which constituted a serious climatic hazard, surprising the unadapted crops to the intense weather cooling. The snow layer reached 22 cm in Caracal in Romanaţi Plain. The analysis of the climatic conditions in the south-west of Romania in the autumn of 2013 is a continuation of some extended studies on climate variability. The paper is useful to specialists, doctoral candidates and master graduates and to all people interested in the climate’s evolution (Bogdan, Marinică, 2007, Marinică et al. 2012, 2013, Sandu et al. 2012).
Keywords: precipitation excess, weather intense cooling, early hoarfrosts.
