• El Niño, La Niña and the Southern Oscillation

  ocean layer (a few tens of metres deep) lies above a thin 'thermocline' layer, with cold water below. An El Niño event can start in several ways, usually with the sea surface temperature raised slightly in the central/east Pacific. This may be, for example, through the action of 'westerly windbursts

• Met Office Deep Dive: A change on the way, but when?

  to this week’s weather lies in the position and persistence of a large area of high pressure, anchored over the UK. This “blocking high” has been responsible for the settled conditions, but also for trapping a layer of low cloud over much of the country. To understand why the high is so persistent

Models show extremely unusual gust strength across parts of Madeira and the Canaries, highlighted by the Extreme Forecast Index (EFI), which flags events that lie far outside typical climatological ranges. These winds will persist

In the global model there are changes to improve boundary-layer processes, the representation of cloud, radiation, warm rain microphysics, and deep convection, whilst in the regional models there are improvements to the treatment of lying snow, sub-grid turbulence and ice
