Assembling our capability for ensemble weather forecasting

a weather forecast try to determine a single ‘black’ or ‘white’ outcome, rather than present a more well-rounded picture of all of the shades of the weather that could possibly come? Up to now, traditional weather forecasting has tended to rely upon determining a single (most likely

and aquaculture further impacted by rising sea temperatures. Power, roads and other infrastructure come under stress from extreme heat events, with knock-on economic consequences. To find out more and access the full report visit https://www.metoffice.gov.uk/services/government/international

. Temperature observations come 1 from the CRUTEM5 dataset (Osborn et al., 2020), from which only post-1900 data are retained, when the coverage can adequately represent the mean regional temperature. The model simulations start at year 1850. The likelihood of extreme heatwaves is calculated under three

, that is, the evidence. In UKCP18, this information comes from observations and outputs from a number of climate models, all with their associated uncertainties. The methodology that allows us to generate probabilities is based on large numbers (ensembles) of climate model simulations, but adjusted according to how

Tropical wetlands and methane - WCSSP case study

of the year. Due to the high water levels in these ecosystems, wetlands typically have low oxygen levels which causes the microbes that live in the soil to produce the greenhouse gas methane.  Methane doesn’t just come from wetlands, however. It has multiple sources and in 2020 a team of international

UK National Climate Science Partnership

? Initial funding from the partnership comes from the Met Office and NERC Centres aligning relevant National Capability activities to address the shared goals of the NCSP.  As the partnership develops, the partners will seek opportunities to fund new projects from public and private sector sources

(5W-13E; 38- 52N) and b) assess the role of anthropogenic forcings in the changing likelihood of extreme heatwaves. Extreme events are defined as exceedances of the previous record anomaly of 4.126 0 C (relative to 1901-1930) observed in year 2003. Temperature observations come from the CRUTEM5 1

Better weather forecasts on Met Office website and app

, resulting in more accurate temperature forecasts, more accurate predictions of rain, hail and snow, and more accurate weather symbols.   “It’s taken big scientific investment to get to this stage, so it’s an important milestone for the Met Office, and there are more exciting developments to come

Weather trends: blocking highs and the amplified jet stream

in mostly dry and sunny weather, with high pressure dominating our weather for the last few months. Occasionally, the high pressure has drifted towards Europe, allowing some weather systems to come through, but it has quickly rebuilt, maintaining the dry and settled conditions.
