Met Office Show Just How Variable UK Weather Is

November 9, 2015

There is another point worth highlighting from the latest 3-month outlook for precipitation from the Met Office, which I mentioned earlier. 

 

   

Year to year variability 

 

They publish this chart, illustrating the range of observations during 1981-2010, for each 3-month period.

What is striking is just how much variation there is in these actual observations, not to mention the 3-month outlook.

Bear in mind that these are 3-month periods, which should therefore tend to suppress much of the month-to-month variability.

 

We pretend we can identify past and anticipate future trends, but such trends are simply drowned out by the weather.

    Paul, we can. Just a qick glance clearly indictates it is wetter during winter 3 month periods and drier during summer 3 month periods, now who would have thunk that!
