Changes in air temperature and precipitation and impact on agriculture

Aridity assessment within southern Romania and northern Bulgaria

“…Topliisky (2006) pointed out that aridity is a characteristic of climate for approximately two-thirds of the territory of Bulgaria in the lowland and plain hypsometric areas, and it is expressed mainly in the June-October period (September). On the basis of the Gaussen-Bagnouls classification method, Nikolova and Mochurova (2012) identified arid conditions in the south of Bulgaria for the July-September period. According to Dragotă et al (2011), Southern Oltenia is one of the Romanian regions which is most affected by aridity and drought.…”

“…According to the Thornthwaite and KÖppen classifications, in Europe, aridity is characteristic only for some parts of the Iberian Peninsula. In recent years, the interest in investigating aridity and climate water deficit as important climate features in the Mediterranean region and South-Eastern and Central Europe, has increased, as shown by the following papers: Andrade and Corte-Real (2016), Chendeş et al (2010), Cheval et al (2016), Hrnjak et al (2014), Kenawy et al (2016), Nikolova and Mochurova (2012), Nistor (2016) and Rego and Rocha (2014).…”
