It is remarkable how many instances of storms becoming inactive and/or not
reaching areas to the south and east of say the north fringes of London
this year where incidentally the highest temperaturea are often located. At
least a dozen times since May and probably more and of course a good example
tonight. This pattern has been observed with increasing frequency in recent
years and in my opinion reflects a slow northward shift of areas of
subsidence with few storms forming over the north of France and moving north
to London.
I expect an increasing amount of thundery developments to occur later in the
year after mid September /October in the SE reflecting a semi Mediterranean
like regime. It is not conclusive proof of climate change but it is in my
opinion a significant signal similar in importance to say a lack of October
snow across the south compared to previous centuries within the Little Ice
Age.
