I wonder if the forecasts of 5 cases (4 missed + 1 false), with 4 happening since 2000 -- may be due to the slowing of the Jet Stream. As the Jet Stream is powered by the opposing forces of cold Arctic air and warm air from the south -- and is now slowing down and wobbling more because the pressure from the Arctic is waning -- this weather engine is perhaps affecting our other weather engine, our ocean currents. What do you think?
