which is really high, with a majority of those saying they did things like securing items around their properties in advance of the storm. so, based on that, we do think the warnings were successful. big storms will always cause disruption, tragically also loss of life, but we are sure that the warnings played a part in ensuring things weren t any worse that week. also, i think it shows how far we ve come in terms of how we prepare for severe weather in the uk, especially since the great storm of 1987. and, when it comes to stormy weather, three named storms in a week, is the uk getting stormier? is climate change making storms stronger when they hit the uk? 0ur long term climate projections do give us some hints. it tells us uk winters are very likely to get milder and wetter, again in the long term. this milder and wetter weather tends to come from the atlantic where the storms develop so that does start to suggest that winter stormy periods are becoming more frequent
in the future. also, there is research into certain types of storms, and in particular the kind that can give us our very strongest winds of all, and it looks like these as well may become more frequent in the long term. more explosive cyclogenesis now, and this time with a snowstorm that slammed into the north east usa injanuary, giving boston its joint snowiest day on record. parts of northern japan had their snowiest january, the city of sapporo saw more than 60 centimetres in 2a hours, the snowiest day in records going back more than 20 years. not the normal view of a greek island but this is naxos injanuary. even in a warming world, there will be bouts of severe winter weather. europe overall had a warmer than average winter. the same storm that hit greece swept across the middle east. this is aley on mount lebanon,
or even dumbing down meteorology, but it has been a real success. i think we are all so connected these days, there is so much available information online and in the media, and storm naming reallyjust helps us to organise that advice into a single, simple message, which everyone can share. so, notjust the met office but also the bbc, the rest of the media, government, emergency services, and of course the public. there is plenty of evidence of this improving the effectiveness of warnings, which is really measured by people taking the right decisions and actions. so, when it comes to storm eunice in february, that combination of the naming of the storm and the red warning for here on the isle of wight and for the first time in london, how did that make a difference in perhaps preventing more loss of life? we do public surveys after each big weather event, and after storm eunice we asked hundreds of people about how they knew about the storm and the warnings and then what they did. and,
of the jet stream at around 30,000 feet or so. a disturbance in the powerful jet stream forces the air aloft to accelerate away, removing air from the top of the column. the column weighs less and so the force it is exerting on the ground, the pressure gets lower. hence, low pressure. near the ground, air rushes in to replace what is lost higher up, and the area of low pressure rotates more and more quickly. and as the process continues, the storm is able to deepen explosively. on a weather chart, you will see more and more isobars appearing, like a dartboard, and if the pressure falls by at least 2a millibars in 2a hours, that is explosive cyclogenesis, or a weather bomb. weather bombs like storm eunice are not that unusual. but it is when explosive cyclogenesis happens near land that their impact can be extreme. eunice s winds were so strong they shredded part of the fabric roof of london s
