December 2024 Global Marine Heatwaves Outlook

Marine heatwaves remain a dominant force on global climate as 2024 ends. Climate Impact Company identifies one dozen well-organized MHW’s with each expected to continue into the New Year. The dominant presence of MHW’s may have slowed La Nina onset. MHW’s bias oceanic regions (and nearby land masses) with above normal strength high pressure aloft (warmer climate) and increased low-level atmosphere moisture to propel over-achieving storms.

Strong Asia-Bering Sea-North Atlantic Index Inspires Important Climate/Weather Ahead

A strong positive phase Asia-Bering Sea-North America (+ABNA) index emerges over the next 2 weeks and cools the North Pacific which leads to (NOAA) La Nina onset and intensity increase, a warming of North America and soaking atmospheric river into the North America West Coast.
