in knots. The knot is defined as a speed of one nautical mile per hour. 1 knot = 0.51444 m s -1 = 1.15078 mile h -1 = 1.853 km h -1 = 1.689 ft s -1 There is a close relationship between surface isobars (line joining points of equal pressure) and wind speed and direction over open level terrain

A low-pressure system, named Storm Aurore by Météo-France, is bringing heavy rain and blustery winds to southern England. Amber and yellow national severe weather warnings are in place across parts of southern England where 60 mm of rain could fall in just 2 to 3 hours leading to a risk of surface

was dominated by high pressure, leading to dull, dry and mild conditions with very low sunshine levels. This ‘anticyclonic gloom’ persisted until mid-month, at which point there was a shift to lower pressure brought by an Arctic maritime airmass. This airmass resulted in colder temperatures and wintry

On Thursday there will be some sunny spells with scattered showers before the jet stream, strengthened by the warm tropical air pushed northwards by Hurricane Ian, sweeps an area of low pressure across the UK on Friday. Deputy Chief Meteorologist at the Met Office, Chris Almond, said
