The key thing to understand is that solar activity causes shifts in the jet stream with consequent changes in weather patterns and triggers processes that lead to storm formation.
Piers CorbynComputer modelling for weather forecasting, and indeed for climate forecasting, has reached its limits.
Piers CorbynI gained a first class degree in Physics at Imperial College London in 1968 and did research in solid state physics, but did not pursue meteorology matters until gaining an M.Sc. in astrophysics from Queen Mary College London in 1981, after which I investigated and attempted to construct theories of solar activity.
