Climate Variability in Spring 2019 In South-West Romania

Abstract

In 2019, the solar activity reached a minimum, the El Nino phenomenon was absent, carbon dioxide concentrations exceeded 410 ppm (the highest level in the last 120,000 years), and climate warming continued. As a result, in southwestern Romania (and not only), the climatic evolutions were marked by a great variability. The warming of the weather started from 14.I.2019 and culminated with the warm March. On 18.III in Romania, the European climatic record of the hottest day of March 18 in the last 120 years was recorded. The precipitations were deficient for extended periods of time, March being excessively dry, and April even on average rainfall, but in areas extended especially in the Oltenia Plain and in the hills area, the drought persisted. The strong instability of the weather that started on 20.IV.2019 and culminated with torrential rains that caused flooding in some areas, abundant hail and tornadoes between 30.V-6.VI, which brought a completion of water supply. The recording of the first moderate heat wave in the period 10-16.VI has restored the drought problem. The paper analyzes the climate variability of spring 2019 and its synoptic causes.
