UK Weather Tracker #22 – November 2018

December 5, 2018 By Nigel

There is no subtle way to say this, our weather in November was boring!

The meteorological year starts in December which is why December appears as the 1st data point in the charts below.  More information on the layout of the charts can be found in this post.  Points lying between the upper and lower deciles are shown as open black circles, points lying between the deciles and minimum/maximum are shown as solid black circles and any month with a new record is shown as solid black squares.

As I explained last month, the addition of a Temperature Range chart (B) means I now have 7 charts to I update every month so I will rotate which 6 appear in the deck above and plot the 7th as a separate chart.  I stated that Sunshine is of least interest in the winter months which means chart C above is now for Frost and the odd one out is Sunshine in chart G here.

There is nothing of note to say about November but it does mark the end of the meteorological Autumn.  I do not track regional statistics every month but I do track temperature by season for each region so I can update the regional temperature chart below.  This shows the Z-Score for each region for the 2018 autumn.  A Z-Score is simply the regional temperature minus the long term average for that region divided by the long term standard deviation for that region.  Doing this, gets around the issue that each region is different on average whereas z-scores all have the same scale, namely number of standard deviations from the mean.

For the UK as a whole, Autumn 2018 was above average in temperature and this was the case in all regions except Northern Ireland.  The Eastern side of England and Scotland were warmest areas whilst the rest of the UK was unremarkable.

 


PS: If you bookmark this link, it will be refreshed with the latest month’s data.  I usually post the update in the first week of each month.
