Over recent days, we’ve seen a noticeable shift in the weather pattern, with the jet stream slipping further south and currently straddling the UK. Out in the Atlantic, the jet is diving even further south, generating a trough, essentially a dip in the jet stream, which is helping to spin up

observations of mid-latitude frontal cloud from both PICASSO and flights based over Northern Scotland carried out over the last ten years. Working with scientists from the Cloud Scale Modelling group who are developing the Cloud-AeroSol Interacting Microphysics (CASIM) scheme for use in the Unified

progressed northwards over Britain from Cornwall to the Yorkshire Coast and the strongest winds in the system developed as a rather narrow stream from the N or NNE over the Irish Sea. The winds reached hurricane force 12 on the Beaufort Scale and were estimated at well over 100mph. Wind speeds recorded

'Tropical cyclone' is the generic term for a low pressure system over tropical or sub-tropical waters, with intense convective activity (e.g. thunderstorms) and winds circulating in an anti-clockwise direction in the northern hemisphere (clockwise in the southern hemisphere). A tropical storm

-member ensemble at four start dates each month (the 1st, 9th, 17th and 25th), over the 24-year period 1993-2016. Thus, for each new forecast, there is a reference set of 672 (7 x 4 x 24) hindcasts. This reference set provides the basis for measuring the deviation of the current forecast away from

potentially climbing into the low 20s. By evening, most showers and isolated thunderstorms over northwest England, southwest Scotland, and Wales begin to fade. However, a few showers persist, particularly in Northern Ireland. Elsewhere, skies clear, though low cloud settles over parts of the north

. The HadCRUT4 global temperature series shows that the average for 2019 as a whole was 1.05±0.1 °C above pre-industrial levels, taken as the average over the period 1850-1900. 2019 is nominally the third warmest year in the HadCRUT4 series. NASA and NOAA have also published their global mean

) to characterise the current climate over the 1981-2010 baseline period. Global and regional climate model simulations were used to assess the projected change in temperature and precipitation for the 2050s (2041-2070- consistent with IPCC AR6). To model and predict future climate it is necessary to make

The Extreme heat warning is in place until Sunday and covers much of the southern half of England as well as parts of eastern Wales, highlighting the potential impacts these levels of heat can have on health, transport and infrastructure.   Thanks to the influence of high pressure positioned over
