in Wales and the south, although again most of any lying snow will be over hills.” Showers in the south will often be accompanied by strong winds, while there is a risk of overnight ice across the north and west especially tonight and Tuesday nights. It could turn more generally wet again later in the week

down the east coast causing severe flooding across many low-lying areas of East Anglia and the Thames Estuary. It was a cold day generally with temperatures well below the late January average. Significant weather event The Stranraer to Larne ferry boat ‘Princess Victoria’ foundered with the loss

(that lie between traditional large eddy simulation and NWP scales, the so-called 'gray zone'), to ensure accurate predictions on the grid scale. Paul is also carrying out research with colleagues from the University of Exeter.  One project is looking at the coupling of slow-fast dynamics, in particular

on the 26th, and cold and unsettled weather continued during the last few days with lying snow penetrating to low levels in some counties. The provisional UK mean temperature was 4.3 °C, which is 0.5 °C above the 1981-2010 long-term average. Mean maximum temperatures were about 0.5 °C below average

precipitation falls as snow and how much as hail. In turn, this could affect other variables (e.g. the amount of lying snow which leads to colder winter temperatures). We find that fixing the error can lead to differences that are significant, i.e. when the differences are larger than the spread (i.e

week Low pressure is likely to lie in the vicinity of the UK into next week, bringing a mixture of showers, longer spells of rain, and some drier interludes. We are carefully monitoring the period of Tuesday to Thursday for the chance that an area of heavier rain moves up from the south

extent lies towards the top end of all these central ranges (Figure 5), a fact likely to reflect the abrupt slowing of ice melt late in the season. However, the median estimate did increase somewhat as the season progressed, becoming closer to the observed extent. Figure 5: Arctic sea ice extent

models there are improvements to the treatment of lying snow, sub-grid turbulence and ice cloud fraction in mixed-phase clouds. The main goal of PS43 is to introduce the new En-4DEnVar scheme to the global ensemble. En-4DEnVar provides an ensemble of initial conditions which are generated through
