warming level of 2 °C and 4 °C. These have been derived from the global projections using statistical techniques. Results overview • There are no compelling trends in storminess, as determined by maximum gust speeds, from the UK wind network over the last four decades. • The global projections over

are not affected by the update: the UK is projected to have hotter, drier summers and warmer wetter winters. However, we have updated this to reflect the updated data values, namely statements: 3.1.2 on the range of summer and winter temperatures in 2070 3.1.3 on the increased chance of seeing

of warming or rainfall changes that are at the top end of what’s considered plausible. Those events which cross ‘tipping points’ – such as the collapse of the West Antarctic Ice Sheet or the breakdown of the Atlantic Meridional Overturning Circulation (AMOC), are also included. AMOC disruption would

, which when burnt produce carbon dioxide. Global warming - a rise in the Earth’s temperature, often used with respect to the observed increase since the early 20th century. Greenhouse gases - gases in the atmosphere, which absorb thermal infra-red radiation emitted by the Earth’s surface

on the outlook for the festive period he said: “Christmas is still over one month away, so it is impossible with this lead time to have any confidence in a detailed forecast for the big day. The only guides this far out that are helpful in determining a forecast are studying the global drivers of weather

An image of the sun during the morning of 16 October 2017 from Met Office Headquarters in Exeter, likely to be caused by a combination of Saharan dust and smoke from Portuguese wild-fires drawn north by the warm southerly airflow; a phenomenon observed widely across southern

the surface area of the UK. Dr Ed Blockley leads the Met Office’s Polar Climate Group. He said: “Antarctic sea ice extent reaches a maximum around the end of September and a minimum around the end of February. At the end of June, the extent of sea ice should be building to a mid-point between

by demonstrating the cross government need for new supercomputing capacity. MV said that he would be leaning in on support for the HPC. JP stated that it would be good for others to write in too. It was agreed that the Secretariat would agree with the sponsorship team at BEIS an approach for getting certain

by a mainly cloudy picture with isolated showers. It was warm in the south-east with Writtle (Essex) recording a maximum of 19.1 °C. Another belt of rain moved southwards through the country on the morning of the 9th, followed by brighter weather with widespread, locally thundery, showers. Further rain moved

. • For clouds to form, the air needs to cool so that the moisture in the air condenses. Discuss mechanisms that cause air to rise and cool. • Convection: Discuss how warmer air rises upwards while cold air sinks down. Point out resemblance of patterns with cumulus cloud tops. • Cloud in bottle: Discuss how
