Manifestation of El-Niño South oscillation in interannual and seasonal variability of air temperature anomalies at the South coast of Crimea

Abstract

The analysis of the relationship between El-Niño–South oscillation and interannual changes in surface air temperature anomalies on the South coast of Crimea is carried out. The El-Niño–South oscillation events are classified during the period from 1950 to 2020 according to the duration, intensity, and onset of the event. Long-range relationships between El-Niño–South oscillation and seasonal variability of surface air temperature anomalies are revealed. The influence of El-Niño on the variability of surface air temperature anomalies in the studied region depends on the duration and intensity of the event. More significant influence is exerted by longer El-Niño events, as well as by shorter but more intensive events. The most influential are El-Niño events of the spring type. In general, El-Niño and La Niña events make a significant contribution to the interannual climate variability on the South coast of Crimea.
