I understand that weather forecasting is not an exact science (ever since I read Hammond Innes books ) but I just don't get how the BBC can make such a mess of their forecasting.
They have input from weather stations all round the UK; a history of weather trends to factor in; latest computers and software and still they often get the prediction either totally wrong - or change their forecasts.
Take today. At 07.20, they were forecasting a high of 29C and sunny intervals. At 09.20 they have changed the forecast to a high of 26C and a chance of rain this afternoon. (Thank the Lord!). When I say 'a chance of rain', the likelihood is 19%,21%,21%,22%,20% and 13% eash hour between 12.00 and 17.00.
And this illustrates my point. Weather forecasting is not an exact science, but they make these incredibly small increments of rainfall every hour!
So, do I need to water the garden or not???????? Or take a brolly to town???????
Why not just say - "Sunny, temperatures up to 26C with a chance of rain this afternoon."
(Glad I got that off my sweaty chest )
BBC no longer use the Met Office to provide forecasts. They went for a cheaper option. I'm convinced the forecasts (not prediction) have become less reliable since, especially regarding rainfall chances. You can always look at animated rainfall radar to see where the rain is and in which direction it is travelling. Which is OK for frontal rainfall, not so good for conventional rainfall which can brew up in relatively isolated pockets. Love lightning is useful too. If all else fails, call the dog in and see if it is wet!
When I was a kid, criticising weather forecasting was a common, tedious joke. Partly because of the Michael Fish Hurricane, but partly because it genuinely was something of a lottery (if my memories as an 8 year old are correct). But it seems to have become pretty accurate over the last decade or so. I cannot remember the last time I was surprised by a rain shower that wasn't forecast.
It wasn't a hurricane...very close but technically didn't meet the criteria. Since then gaps in the data collection system have been filled (especially weather buoys out at sea), satellite technology has come on leaps and bounds and supercomputers can now crunch data and produce forecasts with greater accuracy. So, yes, forecasts have become more accurate and with climate change the probability of a hurricane hitting the more populated areas of the UK has increased. And it's too late to do anything about it apart from try to minimise further excessive negative climate change.
What can CCMB find to moan about today? How about the weather forecasters, that's a classic.
I recall the infamous Katie Hopkins state when she worked for the Met Office that their forecasts were very accurate retrospectively. Great at telling you what the weather has been like but not that great at forecasting the future. Where I live in South Devon the forecast is always totally inaccurate; we don't get much rain when it is forecast and the temperature forecasts are always out by 3 to 4 degrees C.
Now the Meteo Group are giving the forecasts accuracy has not improved. I note also that various weather forecasters give different results.Today some are forecasting thunder at Noon but others don't indicate thunder at all. I just treat forecasts with a pinch of salt and suggest others do the same.
In Pembrokeshire the local radio station has a local weather forecast called the 5 past forecast
There is a chap who’s house at St Brides looks across the bay. The radio station rings him. He looks across the bay sometimes using binoculars and very accurately lets the listeners know what weather is headed their way.
Simple but effective
As a side note:
I was crossing the North Sea the night of that storm, along with hundreds of other Welsh football fans who had attended the Denmark v's wales game the previous day. What should have taken us 19 hours, took 26 hours. When we arrived at Harwich, we had missed our berth and had to anchor at sea. When we finally docked there was no electricity to connect the gangway to the ferry terminal to allow us to disembark.
And another thing!
I was watching the delectable Bennie (closely) at about 22.30 on the nite of the recent thunderstorms and the graphics were abysmal. Absolutely no video of how the storms would cross Wales. I was appalled.
You're right. The Zeebrugge disaster happened in March of that year. To be honest, most of us on board had been drinking quite heavily and the storm hit us early hours in the morning, so we mostly unaffected by it. I can recall hearing the change in sound as the ship's propeller left the water every now and then, but I managed to sleep quite well (testimony to modern ship stabilisers). In the morning we saw the extent of the damage around the ferry.. there were plant pots overturned everywhere, along with broken crockery and glasses. The waves were still up to the observation deck.
I have chuntered about BBC weather forecast inaccuracies since my early 20s - so it isn't just a grumpy old man thing (now I qualify!).
I do look at the BBC forecast on TV or via my phone app, but with little confidence. It may be that in some parts of the country the topography or local micro-climates make any forecasting harder - but the BBC often gets it wrong, or as the OP said it radically changes it's forecast at the last moment, just before previously unpredicted weather hits.
In lists of most accurate UK weather apps the BBC is usually shown down in 6th/7th/8th place of the most popular. Dark Sky or AccuWeather have been top of the list for a while. WeatherRadar is often good, and the Met Office's own app scores higher than the BBC.
Weather forecasting used to be much more accurate, as shown by its part in planning WW2 Operations. Older members will recall that it used to be quite reliable . It's still possible to get accurate forecasts privately but you have to pay for them, which many big industries and farming concerns do.
Unfortunately you have to use proper physics and meteorology to do that rather than "computer modelling ". Thing is though, that such actual science quickly rules out the idea of man made climate change, which is not a conclusion which can be allowed.
If we intend to perpetuate the idea of man made climate change with all the benefits that brings to rich people such as revenue, reduction of competition and a reason to legislate against freedoms, then we must use the politically defined version of science rather than the old version which relied on fact rather than commerce and control.
Therefore the BBC , like all State funded institutions must use "computer modelling" and other methods which are designed to corroborate the claims and predictions of the State and we therefore cannot expect results which are entirely compatible with scientific reality.
Science, like literature and history is now the province of the State and its dumbed down "education" system rather than those who study these disciplines objectively. This isn't new - it's happened in both Germany and the Soviet Union in the past , and it's doomed to eventual failure in the same way. However, since we appear to be content for the moment to put up with it, I'm afraid that we can't expect accurate weather forecasting any more than we can expect truthful history or the exemption of literature from censorship.
If it's rain you want to take a look at:
https://www.metcheck.com/WEATHER/radar.asp
OK at 09.20, the threat of rain at 12.00 was 19%. At 11.21 it was changed to 4%.
Someone clearly looked out of the window somewhere.
I ask again. What is the point?
Just going to consult my fir cones...
