Predictability of climate anomalies in the regions of Northern Eurasia in the spring-summer months in 2024 in connection with El Nino

Abstract

The predictability of climate anomalies in the regions of Northern Eurasia in connection with El Nino phenomena is analyzed. Particular attention is paid to the most likely transition in 2024 from an El Nino phase at the beginning of the year to a La Nina phase at the end of the year, with the greatest probability of high temperatures and dry conditions in European Russia during the spring and summer months, as in 2010. The predictability levels of regional climate anomalies using different El Nino indices are compared. The relationship of the noted seasonal anomalies with atmospheric blockings is considered, taking into account the different phases of the key modes of climate variability like El Nino phenomena and the Pacific Decadal Oscillation. Changes in the predictability of regional climate anomalies under global climate change are discussed.
