Your support helps us to tell the story
From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.
Your support makes all the difference.OVER the past 2,500 years, weather forecasting has moved from superstition to empiricism, and finally to mathematics. Now, thanks to the enterprise of two young meteorologists in Munich, it has reached the pinnacle of scientific evolution - for thanks to the launch of the European Weather Challenge (EWC), weather forecasting is now an international sport.
The rules of the event run over the Internet by Paul James and Michael Sachweh are simple. Entrants (mainly professional forecasters and university departments) must forecast by noon each Friday what the temperature will be at each of 10 widely spread locations in Europe at noon on Monday. Points are given according to the correctness of the forecast, with one point lost for each degree of error.
The first 12-week round of the competition ended in February in a victory for the professional forecasting group Meteo Consult of the Netherlands. The second round is now at its halfway stage, and Meteo Consult are again in the lead, level with the Yunet Weather Team from Belgrade.
I asked Paul James how the entrants' forecasts compared with that old British stand-by of "same as today". The figures he provided are most encouraging. All 18 entrants in the first competition did better than "same as today", the best of them scoring some 25 per cent higher.
Quite apart from the competitive fun, the EWC is providing an objective measure of the effectiveness of modern forecasters. And it confirms what a good job they're doing.
