Why could ENSO directly affect the occurrence frequency of Arctic daily warming events after the late 1970s?
Arctic winter daily warming events have sparked growing interest, particularly in recent years, when Arctic daily temperatures have approached melting point several times. This analysis reveals that the impact of the El Niño-Southern Oscillation (ENSO) on the frequency of Arctic daily warming events...
