Since June, the weather in the UK has been very average and unremarkable and November was again no different, perhaps a bit stormier than normal.\u00a0 The contrast with the first half of the meteorological year is quite notable.
\n<\/p>\n

The meteorological year starts in December which is why December appears as the 1st data point in the charts below.\u00a0 More information on the layout of the charts can be found in this pos<\/a>t.\u00a0 Points lying between the upper and lower deciles are shown as open black circles, points lying between the lower\/upper deciles and the minimum\/maximum respectively are shown as solid black circles and any month with a new record is shown as solid black squares.\u00a0 All data is supplied by the Met Office and can be found here<\/a>.<\/p>\n

\"\"<\/p>\n

Every month I update 7<\/strong> charts in all.\u00a0 I rotate which 6<\/strong> appear in the deck above and \"\"plot the 7th<\/strong> as a separate chart here.\u00a0 Between November & February, Sunshine (chart G) is shown here since that is of least interest in these months.<\/p>\n

How abnormal was November 2024?<\/strong><\/span><\/h4>\n

\"\"Chart H displays my UK Weather Abnormality Index<\/strong><\/span> (see my May 2019 post for details<\/a>).\u00a0 The closer to zero this index is, the less abnormal and thus more “average<\/em>” a month is.\u00a0 The higher it is, the more abnormal the month is.\u00a0 When the index is over 100%<\/strong>, we can describe the month as unusual in some way.<\/p>\n

The abnormality index was 57% <\/strong>this month which is in line with the median\u00a0 This is the 6th month in a row where the abnormality index was around or below the median which contrasts with the 6 months around or above the median for the first half of the meteorological year.<\/p>\n

Regional Variations<\/strong><\/span><\/h4>\n

\"\"November marks the end of the meteorological autumn.\u00a0 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 here.<\/p>\n

This shows the Z-Score for each region for the 2024 autumn.\u00a0 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.\u00a0 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 above or below the long term average.<\/p>\n

The 2024 autumn was slightly warmer than the long term average in the UK overall and in all regions.\u00a0 No obvious regional pattern stands out here.\u00a0 \u00a0For more details about the 2024 autumn, click on the link provided in the list below.<\/p>\n
