Spatiotemporal distribution of aridity indices based on temperature and precipitation in the extra-Carpathian regions of Romania

Aridity assessment within southern Romania and northern Bulgaria

“…The shore of the Black Sea was determined to have a semi-dry climate (Varna), while the Danube Delta semi-dry (Tulcea) or even dry (Sulina). These results are consistent with the results obtained by Croitoru et al (2013) or Cheval et al (2016), who also predicted less dry conditions in the region for the 1991-2020 interval, but the extension of moderately dry conditions within most of the analysed region for the 2012-2050 interval. neposrednoj blizini, u Belogradčiku i Vraci, vrlo humidna (sl.…”

“…According to Dragotă et al (2011), Southern Oltenia is one of the Romanian regions which is most affected by aridity and drought. The aridification process in southern Romania was detected and analysed by Peptenatu et al (2013), Păltineanu et al (2007), by Tiscovschi et al (2013) in Dobroudja, by Pelin (2016) in eastern Romania (Moldavia Plain), and by Croitoru et al (2013) in extra-Carpathian regions.…”

“…Baltas (2007) used it for northern Greece, Coscarelli et al (2004) for Southern Italy, Croitoru et al (2013) for extra-Carpathian regions, Moteva et al (2010) for Bulgaria, Sajjad and Shahzada (2014) for Pakistan, etc. At the annual level (I a ), the index is calculated according to the following formula:…”

“…It has mainly been applied in the Mediterranean region, Portugal (Andrade and Corte-Real, 2016), northern Greece (Baltas, 2007), and Turkey (Deniz et al, 2011). More recently, Croitoru et al (2013) applied it for Romania (extra-Carpathian regions) and Cheval et al (2016) applied it at the continental scale.…”

Do changes in meteorological parameters and evapotranspiration affect declining oak forests of Iran?

“…To achieve this, long-term meteorological data from six synoptic meteorological stations ( Fig. 2) were used to parameterize the De Martonne aridity index (I DM ) (Croitoru et al 2013).…”
