Overall, the coupled ocean-atmosphere system was consistent with La Niña conditions. Convection remained suppressed over the western and central Pacific and enhanced over Indonesia.
Low-level easterly wind anomalies prevailed in the western and central equatorial Pacific, while upper-level westerly wind anomalies continued over most of the equatorial Pacific.
Below-average subsurface temperatures persisted near the surface to ~75m depth in the eastern equatorial Pacific Ocean, with above-average temperatures at depth (~100 to 200m) in the western and central Pacific Ocean. Subsurface temperatures anomalies averaged between 180°-100°W and 0-300m depth were weakly positive in June. La Niña is favored to continue through 2022 with the odds for La Niña decreasing into the Northern Hemisphere late summer (60% chance in July-September 2022) before increasing through the Northern Hemisphere fall and early winter 2022 (62-66% chance).ĭuring June, below-average sea surface temperatures (SSTs) weakened across most of the central and eastern equatorial Pacific Ocean with SSTs returning to near-average in the east-central Pacific, as reflected by the Niño indices, which ranged from -0.4☌ to -1.2☌ during the past week.
