, 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

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

previously. This paper is the third in a series of three reports from the Met Office Hadley Centre that address the recent pause in global warming and seek to answer the following questions. What have been the recent trends in other indicators of climate over this period; what are the potential drivers

. 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

. “But for the vast majority, I think it will be a dry and a bright day tomorrow with some good spells of sunshine lifting the temperatures. A warmer day than today, feeling warmer because the winds will be light and with a bit of sunshine, we're likely to see those temperatures more widely over 20°C. 24, 25°C

day – and a simple traffic light system was developed to signify potential hazards. Supported by: Fund Manager: Spreading the message Developing the forecasts was one thing, but getting them out to remote communities across a vast geographical area was another. To be effective, it was crucial

and rain will begin to approach the far northwest later in the night. Further south, areas such as Wales, southwest England, and the Midlands may see light rain or drizzle under low cloud, while other regions remain dry with variable cloud cover. It will be a mild night for most. Outlook for Saturday
