Months highlighted in bold had an abnormality index exceeding 100% indicating unusual weather. I usually post the update in the first week of each month.Ĭlick the relevant month to see what the weather was back then. PS: If you bookmark this link, it will be refreshed with the latest month’s data. Overall the west of the UK recorded slightly warmer winters than the east. It was the 8th warmest winter in the UK overall which was replicated in most regions. 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. 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. This shows the Z-Score for each region for the 2022 winter. 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. Regional Variationsįebruary marks the end of the meteorological winter. 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. When the index is over 100%, we can describe the month as unusual in some way. The higher it is, the more abnormal the month is. The closer to zero this index is, the less abnormal and thus more “average” a month is. How abnormal was February 2022?Ĭhart H displays my UK Weather Abnormality Index (see my May 2019 post for details). Between October & March, Sunshine (chart G) is shown here since that is of least interest in these months. I rotate which 6 appear in the deck above and plot the 7th as a separate chart here. All data is supplied by the Met Office and can be found here.Įvery month I update 7 charts in all. 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. More information on the layout of the charts can be found in this post. The meteorological year starts in December which is why December appears as the 1st data point in the charts below. In fact it was the 7th warmest February on record and resulted in the 8th warmest winter we’ve had in the UK. It was a warm and wet February this year in the UK.
