  lying above the observed threshold. If the observed value of the UK annual mean temperature anomaly can be treated as an extreme value, then a Generalised Pareto Distribution (GPD) is fit to the model tail data and an exceedance probability is found from the continuous approximation of the tail

• Summer_2026_attribution_reportpdf

  distributions are estimated. Exceedance probabilities are then calculated in one of two ways. If the observed value of the UK summer mean temperature anomaly is not an extreme value, then the exceedance probability is the empirical fraction of model values lying above the observed threshold. An extreme

  , an advantage that is not readily available from statistical methods. To generate the ensemble, the starting conditions for the forecast are varied slightly to make 41 individual predictions (known as ensemble members). The forecast probability that the number of storms will lie in predefined ranges

  breaks of sunshine. The high pressure has been slow-moving, remaining in place for the rest of the current week. This stability has resulted in misty and murky conditions, with temperatures creeping into the low teens for many areas. The reason for this stubborn high pressure lies high in the atmosphere

  storm forecasts compared to reference forecast (frequency of occurrence over preceding 180 days) (RPSS: relative improvement of probability forecast over reference forecast in predicting category which observation fell into) • Point averages for day 1 lie above no-skill line, & most of days 2-4

• Factsheets

  Kingdom lies in the latitude of predominantly westerly winds where depressions and fronts move bands of cloud and rain eastwards or north-eastwards across the North Atlantic. Between the depressions there are often small mobile anticyclones bringing welcome fair weather. Climate of the British

  . In total low-lying coastal areas received only around 50mm or less, however much of the high ground received 100 to 150mm, with some locations exceeding 150mm. The wettest areas were across the central Cumbrian fells, which received 200 to 300mm of rainfall and in a few locations 300 to 400mm. Upland

• September 2010 Sea Ice Outlook

  anomaly is then added to the HadISST dataset 1989-2002 climatology to give a prediction for September 2010 of 5.5 million square kilometres. Despite the known model deficiencies, it is encouraging that this estimate lies in the range of the June Outlook report projections. Figure 2: GloSea4 forecast
