A new look at Central England Temperatures

I thought I would try and find a new way to visualise the latest Central England Temperature data which I download from the Met Office. I did it by splitting the window in my Daily CET application into four columns, each column as you can see contains a grid and a pie chart. The first column looks at the mean and anomalies over the last seven days (week), the second the last 30 days (month), the third the last 90 days (season), and finally the fourth column displays the means of the last 365 days (year).

Using these columns it’s easy to see the latest state of play with the CET series, and how warm it’s running at the moment, which may have something to do with AGW😉. Adding the pie charts really helped identify some of the hidden warm periods in the series, such as the five warm 30 day spells in the 1940’s and the four warm 90 day spells in the 1920’s. It’s clear from the pie charts that half of the warm 365 day periods have occurred in the 21st century, it’s also interesting to see just how exceptionally warm the last seven days (8th to 14th of April) have been across central England, in fact the warmest seven day spell for that particular period in the whole daily series which started in 1772.

For the keen sighted amongst you’ll notice that I didn’t follow the strict definition of what constitutes a decade for simplicity’s sake.
