European temperature anomalies in the cold period associated with ENSO events

Abstract

Abstract El Niño (EN) and La Niña (LN) manifestations in the air surface temperature fields over the Europe are studied in present paper using pan-European E-OBS 19.0e gridded data for 1950-2018 and 20CRv2c reanalysis data for 1870-2014. Particular accent was put on winter severity in the Azov Sea region. Taking into account the Eastern and Central types of both EN and LN events sorted out previously, composites of monthly and ten-day air temperature anomalies were obtained for each type of events. The anomalies of each month from October “0” year (the year when event began) to April “+1” year (the year following “0” year) were analyzed. The typical features of statistically significant manifestations in European air temperature for the Eastern and Central types of EN and LN events were described.
