turned more settled. A blocking high pressure system to the east of the UK led to overcast but settled conditions for the next few weeks, with below average temperatures and some scattered showers. Occasional frontal systems brought rain, sometimes wintry over high ground. Scotland saw some snow
and almost zero in coupled simulations. (box 6) • Is the weak surface solar feedback closely related to the weak NSHF standard deviations? • Does the strong latent heat feedback generate strong zonal pressure gradients (Lindzen & Nigam 1987) and influence recharging of the warm water pool ? • Can
Low pressure will dominate this weekend, bringing wet and windy conditions for many. As we move into the new working week, there is potential for more disruptive weather and further weather warnings may be issued.
downpours will be far from welcome, potentially leading to tricky travel conditions and localised surface water issues. The best chance of any dry weather will be across parts of Northern Ireland, northeast England and southeast Scotland. Temperatures will be near normal to rather mild, tempered by brisk
to be associated with higher air temperatures due to the formation of mixed-phase (ice and water) clouds which radiate more heat downwards toward the surface. The unusual weather conditions are due in part to blocking high pressure systems frequently situated over Scandinavia and Alaska (Figure 3b

and, separately, for southern England.” Flood risk from rain and snow melt The milder air in the south means any precipitation will fall as rain across southern Wales and central and southern England. Combined with some melting snow in places, there is the risk of some surface water flooding with already
within this arm may have been rather low, although uncertainty in ice concentration is large in summer as satellites struggle to distinguish open water from melt ponds on the ice surface. Figure 2. Arctic sea ice extent on 9th August 2023, with 1981-2010 average extent indicated in orange
