. Sometimes the vortex can appear as a slender rope-like form, particularly when the tornado is weakening; sometimes a tornado can be almost invisible, observable by the debris thrown up from the surface. Tornadoes typically spin anticlockwise in the Northern Hemisphere (cyclonically). Total destruction

cover and in spring and summer, when the sea is cool relative to the land, there is little convective cloud over the sea. Coastal areas are then favoured by high sunshine amounts, whereas convective cloud o en forms inland. The graphs show the average monthly sunshine totals for Waddington

less rainfall during these summer months, affecting Jilin and Liaoning. Figure 2 shows how total water resources in Liaoning (grey) were significantly lower in 2014 than in previous years. Time series of total water resources in Liaoning Why focus on the Northeast Farming Region? The NFR accounts

and into the start of next week. Amber warnings for rain have been issued for South Wales, and Cumbria where accumulations are particularly notable, with potentially over 200mm of rain over 48 hours. More widely, totals of 40-70mm are likely, with over 100mm on higher ground of western Britain and up

-term average total. Parts of southeast England saw heavy rain, accompanied by strong winds, spread across the area on the last two days of the month. The largest rainfall totals were recorded over the North Downs, where there was in excess of 40mm at Lenham in Kent. The rest of the UK that day

mean value for Summer is 14.37°C, which is 0.22°C below the 1991-2020 average. The provisional total for Summer is 241.3 mm, which is 95% of the 1991- 2020 average. The provisional total for Summer is 491.6 hours, which is 97% of the 1991- 2020 average.
