The pressure below, which traveled between Iceland and the British Isles over the weekend, brought strong winds, heavy rain and high waves to the coasts of Ireland and Scotland. The air pressure in its center dropped rapidly. It decreased by 26 hPa in 24 hours:
• November 10 12:00 989 hPa
• 10 November 18:00 982 hPa
• November 11 00:00 979 hPa
• 11 November 06:00 972 hPa
• November 11 12:00 963 hPa
In cases where the decrease in air pressure in the middle of the pressure below is very fast and the storm thus gains strength, we speak of so-called cyclogenesis. This phenomenon occurs over the North Atlantic or off the east coast of the United States several times a year.
The Atlantic affects the weather in Europe
Numerical models assume that in the next ten days, several deep pressure depressions will form in the North Atlantic, which may also have a significant effect on the European circulation.
