Marine Heat Waves Dominate Australia/South America Climate Pattern

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.
