Getting the most (research) attention regarding a new phenomenon referred to as marine heat waves (MHW) is typically the Northeast Pacific MHW and more recently in research published in Journal of Climate, the East Asia/West Pacific MHW. However, the southern hemisphere has certainly acquired large areas of surface/subsurface water much warmer than normal and well-correlated to upper atmosphere pressure patterns somewhat stagnant in character leading to long lasting climate regimes featuring both very wet and dry-to-drought regimes.

The mega-cluster ensemble indicates an area of cold weather in Russia may strengthen and intensify over the next 15 days driven in-part by above normal snow cover which recently reached Eastern Europe.

The Climate Impact Company constructed analog (CIC-CA) climate forecast for South America during meteorological summer 2022-23 indicates persistent anomalous heat and dryness in Argentina where flash drought is quite possible. The dryness extends to Southeast Brazil although less consistent. Far Southeast Brazil has a drought risk for summer 2022-23. The remainder of Brazil Crop Areas is normally wet with diminished drought risk.
