New Zealand Marine Heatwave/Climate Could Add to Australia Drought Risk

A semi-permanent summertime high-pressure ridge in the vicinity of the New Zealand marine heatwave much of the past 10 years is likely to regenerate during summer 2023-24.

Pattern Reversal: Amundsen Sea Trough Replaced by Ridge; Teleconnection to Brazil is Hot/Dry Ridge

The latest 15-day upper air forecast for the southern hemisphere (by GFS) reveals an amplifying titanic upper-level high pressure ridge developing southwest of South America. Previously, the 2020-23 semi-permanent Amundsen Sea upper trough was “locked-in” the previous 30+ days and responsible in part for a wet pattern for much of Chile, Argentina, and Brazil. The pattern is about to reverse.

Correlating Northeast Pacific SSTA and Europe Winter Temperature

When was the last cold winter season in Europe? Sprawling meteorological winter (DEC/JAN/FEB) cold was last observed during winter 2012-13. Since that time, 8 of 10 winter seasons have been warmer than normal across Europe. During the past 30 years, 7 widespread cold winter seasons have been observed clustering in the mid-to-late 1990’s and in the 2008-2013 period.
