How autumnal high pressure brings on the dark doldrums
High-pressure weather systems in the UK during colder months can lead to 'anticyclonic gloom,' a phenomenon characterized by trapped low clouds and fog. This weather pattern poses a significant challenge for renewable energy, as it reduces the efficiency of both solar and wind power generation.
Why it matters
Understanding these meteorological patterns is critical for energy grid management and the transition to sustainable power sources in Northern Europe.
Anticyclonic gloom also poses challenges for renewable energy generation, reducing solar and wind power output.

Prefer the Guardian on Google In summer, a high-pressure system over the UK usually means fine weather. But in the colder months it can result in anticyclonic gloom, characterised by grey skies, mist, fog and drizzle.
A settled high-pressure system brings stable conditions and impedes the usual vertical movement of air. This is a recipe for sunshine when humidity is low, but can act like a lid, trapping atmospheric moisture near the surface.
