and dramatically, something meteorologist call explosive cyclogenesis. now, imagine a column of air from the ground up to the level of the jet stream at around 30,000 feet or so. a disturbance in the powerfuljet stream forces the air aloft to accelerate away, removing air from the top of the column. the column ways left and so the force it is exerting on the ground, the pressure gets lower. the column weighs less and so the force it is exerting on the ground, the pressure gets lower. hence, low pressure. nearthe 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 hap
would work and we could be seen to be trivialising bad weather or even dumbing down meteorology, but it has been a real success. i think we are also 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 difference in perhaps preventing more loss of life? more loss of life? we do public surve s more loss of life? we do pub
a couple of times in a decade. but the extremity of it, that is that. i wouldn t say it was a surprise but that is the most concerning factor, that we have gone from literally the south east of australia burning, to literally the south east of australia flooding. so, the extremes that we have seen lately, while they have been unprecedented, currently speaking, in the future they will no longer be unprecedented, they will be more like normal. now, that is not to say that they will occur every single summer because especially in australia, we can flip from really dry conditions to really wet conditions within a matter of a couple of years, but these events will look less extreme and more closer to normal because of how extreme future events will be. february in madagascar and cyclone batsirai is the second of five tropical weather systems to impact the island so far this year. thousands have lost their homes. entire villages have been swept away. many people have died. cyclones, the same
asked hundreds of people about how they knew about the storm and the warnings and then what they did. and, for example, in south east england, we found that 99% of people were aware of the red warning. and also crucially 91% said they took action, which is really high, with a majority of those saying they did things like securing items around their properties in the path of the storm. based on that, we think the warnings were successful. big storms will always cause disruption and tragically loss of life, but we are sure that the warnings ensured played a big part in ensuring things were not worse. also it played a part in how we prepare for weather events at the uk, especially after the big storm of 1987. it events at the uk, especially after the big storm of 1987. the big storm of 1987. if the uk caettin the big storm of 1987. if the uk getting stormier? the big storm of 1987. if the uk getting stormier? is the big storm of 1987. if the uk getting stormier? is climate . the b
a new record for england s strongest wind gust during a remarkable spell of stormy weather across the uk. a driver s worst nightmare caught on dashcam, a lorry overturned in extreme winds in oxfordshire during storm eunice, the second and most powerful of three named storms to hit the uk injust one week. thankfully, the driver wasn t seriously hurt. another lucky escape in london which was covered for the first time by a red weather warning. falling trees caused damage and widespread travel disruption, many people filming the storm s disruption themselves. oh, my god, i caught that on video! and even falling steeples, an unusual impact of the storm in somerset. an unlikely beneficiary of the storm, live streaming of planes battling the winds as they landed at heathrow attracted thousands of new viewers. and here on the coast of the isle of wight, almost invisible in the sea spray,
