  within the tail of the distribution), then the exceedance probability is the empirical fraction of model values lying above the observed threshold. If the observed value of the UK summer mean temperature anomaly can be treated as an extreme value, then a Generalised Pareto Distribution (GPD) is fit

  is the empirical fraction of model values lying above the observed threshold. If the observed value of the UK summer 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

  , shows deposited snow as white, the same colour as the clouds which are also present in this picture. The lower image shows a composite that makes use of some different near-infrared channels where the solar radiation is absorbed strongly by the lying snow, producing a characteristic red colour

  -27 cm were measured in various locations. Photograph taken in Sutton, Surrey (reproduced by permission of Roger White). Previous snowfall The last time widespread snowfalls affected the UK was in February 1991. From the 8th to the 14th, there was over 20 cm of lying snow over the eastern half

  numerical techniques for ocean modelling beyond NEMO? A: This is unlikely to happen as part of ExCALIBUR as NEMO lies at the heart of the modelling system as it stands. If NEMO proved to be completely unfit for purpose after WP1 activity 2 then there could be an element

  evaporating back to the atmosphere where it can form as clouds and re-fall as rain again. In fact, the behaviour of trees and plants can control the amount of water being evaporated and therefore the amount of rain which can subsequently fall. The reason lies in the tiny openings on the leaves

There may be a greater than 10% chance that the real-world response lies outside this range and this likelihood cannot be accurately quantified. • We cannot rule out substantial additional sea level rise

  (Table 1). It should first be highlighted that the observed ACE index in a given year is, by forecast definition, expected to lie within the 70% prediction interval approximately 7 out of 10 times. Thus in some years the observed number will lie outside of this range. However, in 2013, the observed ACE
