these features. 5.1.1 Method 1 (RA) This is the most basic method and is a simple 12-month running average. At each hour in the time-series calculate the 1-year average of the baseline mass mixing ratios centred on this hour (y mc ). This is the longterm trend component, subtracting this from the actual

expected throughout the period. This is done using a dynamical seasonal prediction computer model of the global atmosphere-ocean system developed in the Met Office’s climate research division, the Hadley Centre. The seasonal prediction model is based on a Met Office Hadley Centre climate model

, and improvements to the way mixing is represented in the boundary layer under certain cloud regimes has corrected a long-standing problem of unrealistic temperature profiles. In the tropics and sub-tropics, convection has more realistic structure and spurious light rain/drizzle is reduced

. Other major centres of population include Peterborough, Norwich, Ipswich, Cambridge, Lincoln, Grimsby and Hull. Temperature The mean annual temperature over the region varies from around 9.5 °C to just over 10.5 °C. Variations in temperature depend on both altitude, with a decrease of about 0.5 °C

the day, perhaps a few light showers in the morning. Cloud clearing south to allow some clearer spells later. Chance of cloud-free hill tops above 800m: 30%, the very highest summits are likely to be above the cloud top. Cloud tending to lift off the lower summits from mid-afternoon onwards. Low

Tuesday night will be mostly dry with variable cloud. Central and southeastern England will start clear but may

Forecast for Sunday 28 Dec 2025 2025-12-28 Weather: Rather cloudy with some chance of the odd outbreak of light rain or drizzle possible, but most staying dry. Strong easterly summit winds bringing a severe wind chill. Maximum wind: East 30-35mph with gusts
