First +IOD/El Nino Inspired Australia Heat Wave of Season is Ahead

The largescale climate affecting Australian climate is becoming established: Positive phase of the Indian Ocean Dipole and the warm phase of El Nino southern oscillation. Combining the two regimes dramatically increases anomalous hot and dry climate risk for Australia for the summer season. The first heat wave is ahead for early November.

Desperately Needed Significant Precipitation Ahead for Central Europe

A series of STRONG upper troughs finally breaks down the persistent drought-producing high pressure ridge dominating Europe climate for much of the past 4 months occurring over the next 1-2 weeks. The second trough rolling across Central Europe next weekend brings potential excessive precipitation to reverse the historic low river levels.

Historically Intense Polar Vortex is About to Meet El Nino Warming

The strongest polar vortex on record as defined by the arctic oscillation and especially the North Atlantic oscillation indices has occurred in 2018. +AO/+NAO contributed to the 4th warmest warm season on record for the U.S. and also caused historical Europe drought. Now...due to seasonality...the strong polar vortex is producing record early season snow cover across Canada enabling cold air generation infiltrating the U.S. pattern. Meanwhile immense equatorial subsurface warming is ready to ignite what may be a strong El Nino. The warming influence of El Nino will clash the chilly polar vortex regime by late autumn in North America causing more extreme climate.

A Warm Ocean Leads to a Big Year for Northern Hemisphere Tropical Cyclones

A whopping 165% of normal accumulated cyclone energy (ACE) has been observed in 2018 through October 11 across the ocean basins of the northern hemisphere. The East Pacific is a leading contributor (247% of normal) plus an over-achieving North Atlantic basin (130% of normal). A leading contributor to the well above normal activity is a warmer than normal ocean.
