patterns are often associated with an amplified jet stream. The jet stream is a fast-flowing ribbon of air high in the atmosphere that helps to steer weather systems around the globe. An amplified jet stream is one that has large waves, or "meanders," which can create areas of high and low pressure

, aimed at stakeholders including the SPF ExCALIBUR Programme Board and Steering Committee, has been informed by consultation within the Met Office, with UKAEA, and with domain experts from the UKRI community. This Science Plan is intended to complement the ExCALIBUR activities that are funded

ahead. What is an SSW? Sudden Stratospheric Warming (SSW) is sometimes linked to the onset of cold weather in winter. The term SSW refers to what we observe, rapid warming in the stratosphere, between 10 km and 50 km altitude. You may have heard of the jet stream which helps to steer Atlantic weather

to rise again over the weekend. A deeper look at the meteorological drivers behind the change shows a strengthening jet stream, influenced by a sharp temperature gradient across North America, is helping to steer low pressure systems toward the UK. This will bring more unsettled weather through the Bank

unsettled and variable period ahead, with a mix of rain, showers, and occasional dry spells. So, let's get into it.  A Shift in the Weather The jet stream, although not particularly strong for this time of year, is currently sweeping across the UK, steering a series of weather systems. This has brought

northerlies, sunshine and showers Winds will be the main story on Saturday, especially across the far north of Scotland and along North Sea coasts, where gusts in exposed locations may approach gale force. Many areas will see a brisk, blustery feel. The northerly will also steer frequent showers

system has become what meteorologists call a “blocking high”—a stationary pattern that prevents other weather systems from moving in. This blocking high has been reinforced by an amplified jet stream—a high-altitude current of fast-moving air that normally helps steer weather systems. When the jet

influencing the UK’s weather this weekend is an area of low pressure situated to the southwest. This system isn’t being steered along by the jet stream, which lies far to the south across Spain and Portugal. As a result, the low is slow-moving and will gradually weaken in place rather than sweeping
