![]() "Dawlish" wrote in message ... Not surprising to see there are others on here who are concerned that the plethora of weather warnings about severe (or extreme!!) weather that have been issued recently have resulted in so little severe, or extreme, weather. The accuracy of these can only be judged from the outcomes. Communication about how effective that site is relies on a small part of an annual report. There's nothing to tell people how likely something is to happen, apart from saying you have a 60% (early warning), then an 80% (severe warning) that severe, or even "extreme" weather is in the offing. How many individuals who have heard a weather warning in the last 2 weeks (and I've lost track of how many there have been) have ACTUALLY experienced severe, or extreme weather? 60%? 80%?? Nothing like those percentages have experienced what has been forecast and I don't need to monitor every severe weather warning to know that. Everyone knows it. I thought they meant that there is (e.g.) a 60% chance of that weather occurring somewhere within a particular area not that 60% of people will experience it, that is to say 60% of that area will experience it. So is it the probability that any one point in an area will experience it, if that's the same thing? The warnings don't read that way to me but I never understood stats. Or is it 40% chance of no one experiencing it ? Tom |

Tom- Hide quoted text - - Show quoted text - The headline on the flash warnings page is this: "These are issued when the Met Office has 80% or greater confidence that severe weather is expected in the next few hours". There is nothing on that front page to explain anything about what the "80%" actually refers to. I think people are expected to simply make their own mind up what it means. If you click on the present warning, for Highlands & Eilean Siar, you find this, together with; "These are issued when the Met Office has 80% or greater confidence that severe weather is expected in the next few hours": "Showers will be heavy and thundery this afternoon and may give accumulations of 15 to 25mm within a few hours." Does that mean: an 80% chance of a heavy shower in that area; an 80% chance of a heavy shower in all of that area; an 80% chance that everyone will see a shower at some time in the 9 hour period for which the warning is in place; or some other explanation involving 80%. It's as clear as the provibial very wet soil which almost certainly will have formed in parts of the highlands this afternoon. In addition, does 15-25mm really constitute "severe" weather? It certainly isn't in any way extreme, but the public are told to expect "severe, or extreme weather" in every single weather warning. there is no distinction. I think the public are probably fed up to the back teeth of being told they can expect "severe, or extreme" weather and not getting anything more than wet when they go for a walk, or out in the car. Cue; "well how would you feel if there was no warning and severe weather happened?". Is that the ONLY reason for these blanket area warnings when the real reason is that the forecasting of ACTUAL severe weather in a place, at a particular time and for a period of time is presently beyond anyone. The MetO site implies that it is within the capabilities of the MetO to forecast severe weather for us, the general public, you and me. I'm afraid that it can't, beyond blanket warnings in which, sometimes, extreme weather is bound to occur. I know the MetO is caught between a rock and a hard place. I know expectations are high and on the same page it states: "The Met Office has responsibility for providing weather warnings for the UK". Just tell us how bloody difficult it is and for an individual's location, the severe weather may not actually happen and we can't be any more accurate than that, instead of this insufferable papering over the cracks of forecasting at the absolute limits of possibility. People would then actually begin to understand why the MetO warnings site gets it wrong so often! We pay for this (FHS!) and the site treats us like idiots, expecting us to forgive every inaccurate forecast, but also expects us to react if there actually is severe weather - how can we actualy tell? Ring the highways authority, perhaps? |

Another vulture post from the Tullet. Nothing to do with the thread, just a personal attack, hanging on the coat tails of someone else's criticism. He's never actually been brave enough to cast the first stone, but doesn't like me and will contribute to that dislike after someone else has said some silly personal insulty stuff. Can you do nothing else, dear boy? Maybe because someone needs to, is the answer to your why? question. You can be bored, or not Steve and if you don't like me, killfile me. Easy. However if you decide to post some kind of idiocy that needs challenge, expect a challenge. Same with smug, who descended from his eyrie up on Haytor simply to have a go, then never returned to back up the highly questionable and patronising effort that he posted. Same with others. Have either you, Steve, or Tullet got anything, hopefully intelligent, to say on the topic of severe weather forecasts? No? Then would you mind being asked politely to fly back to your tree? A feeling that there is safety in numbers excuses no-one. Insults are hardly likely to put me off. Do feel to have a pop anytime, but expect a response if you do. I'd always reserve that particular right and its a right that few people would deny anyone. |

I suspect you crave respect too, and you know there are many points of view you put across that I and probably others agree with, for example, that the MetO severe weather warning service does need improving but I feel that I for one can never have a constructive dialogue with you because you always seem to be on a one man crusade!

Will -- You know very little about me Will, but purport to. Instead of trying to psychoanalyse me, try returning to answer the question I put to you: how accurate do you feel the MetO 10 day forecasts are, based on the stats produced on the MetO site? It's going to be an awkward question to answer, I know, when you told me this: "Any meteorologist worth his salt knows that to just look at deterministic T+240 is madness as that is bound to oscillate wildly most of the time. Use the ensembles FHS." That's why you are now ducking the answer and throwing up a smokescreen by trying to deflect attention by writing a post focusing on me (after trying to say that no one replies; like I said, you do. I know you'd like no-one to reply as then I wouldn't ask you these horrid, difficult questions, would I?) Will, the outcome forecast success percentage at 10 days, by the MetO, is very low. How do you reconcile your views about that "must use" piece of data, when the outcomes from using it are so low? The trouble is Will, is that I ask difficult questions and I do that from experience and knowledge, not from an imagined (by you) "crusade". There are many areas of meteorology where I read and learn from posts, instead of contributing, but this is an area where there is very little forecasting success and it is no good you hiding behind accepted wisdom, when the accepted wisdom falls down upon analysis. Your knowledge of success rates with forecasting at 10 days is quite obviously very limited; as is your knowledge of me! *)) |
