Here along the west coast, the La Nina'ish teleconnections (not necessarily SSTA's at that point) suggests an atmospheric origin in 2019-20 prior to the oceanic La Nina 2020-21. Since the same anomalous Wx pattern is persisting through 2020-21 (resulting in 2 yrs of record heat and drought),
is it possible that 2021 was really the 2nd year of La Nina (weather-wise) and we may now hope for a slow return to more normal conditions in 2021-22?
