Fig. 2: Evolutions of SST and atmospheric anomalies related to the early spring ALI.
From: Enhanced impact of the Aleutian Low on increasing the Central Pacific ENSO in recent decades

Anomalies of 850-hPa stream function (shading) and winds (vector) in a Mar(0), b AM(0), c JJA(0), d SON(0), and e D(0)JF(1) regressed upon the normalized ALI in Mar(0) over 1996–2018. f–j as in a–e, but for the evolutions of SST (shading) and precipitation (stippling) anomalies. Only the SST, precipitation and stream function anomalies exceeding the 95% confidence level are shown.
