It was a warm and wet February this year in the UK.\u00a0 In fact it was the 7th warmest February on record and resulted in the 8th warmest winter we’ve had in the UK.
\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 minimum\/maximum 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 charts in all.\u00a0 I rotate which 6 appear in the deck above and \"\"plot the 7th as a separate chart here.\u00a0 Between October & March, Sunshine (chart G) is shown here since that is of least interest in these months.<\/p>\n

How abnormal was February 2022?<\/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” a month is.\u00a0 The higher it is, the more abnormal the month is.\u00a0 When the index is over 100%, we can describe the month as unusual in some way.<\/p>\n

The abnormality index was 112% this month, more or less on the upper decile indicating a abnormal month, certainly enough for it to be notable.<\/p>\n

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

\"\"February marks the end of the meteorological winter.\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.\u00a0 This shows the Z-Score for each region for the 2022 winter.\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

It was the 8th warmest winter in the UK overall which was replicated in most regions.\u00a0 Overall the west of the UK recorded slightly warmer winters than the east.<\/p>\n
