How Google’s DeepMind tool is ‘more quickly’ forecasting hurricane behavior
When then Tropical Storm Melissa was churning south of Haiti, Philippe Papin, a National Hurricane Center (NHC) meteorologist, had confidence it was about to grow into a monster hurricane.As the lead forecaster on duty, he predicted that in just 24 hours the storm would become a category 4 hurricane and begin a turn towards the coast of Jamaica.No NHC forecaster had ever issued such a bold forecast for rapid strengthening.But Papin had an ace up his sleeve: artificial intelligence in the form of Google’s new DeepMind hurricane model – released for the first time in June.And, as predicted, Melissa did become a storm of astonishing strength that tore through Jamaica.
Forecasters at the NHC are increasingly leaning hard on Google DeepMind.On the morning of 25 October, Papin explained in his public discussion and on social media that Google’s model was a primary reason he was so confident: “Roughly 40/50 Google DeepMind ensemble members show Melissa becoming a Category 5.While I am not ready to forecast that intensity yet given the track uncertainty, that remains a possibility.“It appears likely that a period of rapid intensification will occur as the storm moves slowly over very warm ocean waters which is the highest oceanic heat content in the entire Atlantic basin.”Google DeepMind is the first AI model dedicated to hurricanes, and now the first to beat traditional weather forecasters at their own game.
Through all 13 Atlantic storms so far this year, Google’s model is the best – even beating human forecasters on track predictions,Melissa eventually made landfall in Jamaica at category 5 strength, one of the strongest landfalls ever documented in nearly two centuries of record-keeping across the Atlantic basin,Papin’s bold forecast likely gave people in Jamaica extra time to prepare for the disaster, possibly saving lives and property,Google DeepMind has been making weather forecasts for a few years now, and the parent forecast system from which the new hurricane model is derived also performed spectacularly well in diagnosing large-scale weather patterns last year,Google’s model works by spotting patterns that traditional time-intensive physics-based weather models may miss.
“They do it much more quickly than their physics-based cousins, and the computing power is less expensive and time consuming,” Michael Lowry, a former NHC forecaster, said.“What this hurricane season has proven in short order is that the newcomer AI weather models are competitive with and, in some cases, more accurate than the slower physics-based weather models we’ve traditionally leaned on,” Lowry said.To be sure, Google DeepMind is an example of machine learning – a technique that has been used in data-heavy sciences like meteorology for years – and is not generative AI like ChatGPT.Machine learning takes mounds of data and pulls out patterns from them in a such a way that its model only takes a few minutes to come up with an answer, and can do so on a desktop computer – in strong contrast to the flagship models that governments have used for decades that can take hours to run and require some of the biggest supercomputers in the world.Still, the fact that Google’s model could outperform previous gold-standard legacy models so quickly is nothing short of amazing to meteorologists who have spent their careers trying to forecast the world’s strongest storms.

In the coming offseason, Franklin said he plans to talk with Google about how it can make the DeepMind output even more helpful for forecasters by providing additional under-the-hood data they can use to assess exactly why it is coming up with the its answers.“The one thing that nags at me is that while these forecasts seem to be really, really good, the output of the model is kind of a black box,” said Franklin.There has never been a private, for-profit company that has produced a top-level weather model which allows researchers a peek into its methods – unlike nearly all other models which are provided free to the public in their entirety by the governments that designed and maintain them.While Google has made top-level output of DeepMind publicly available in real time on a dedicated website, its methods have still largely been hidden.Google is not alone in starting to use AI to solve difficult weather forecasting problems.
The US and European governments also have their own AI weather models in the works – which have also shown improved skill over previous non-AI versions.The next steps in AI weather forecasts seem to be startup companies taking swings at previously tough-to-solve problems such as sub-seasonal outlooks and better advance warnings of tornado outbreaks and flash flooding – and they are receiving US government funding to do so.One company, WindBorne Systems, is even launching its own weather balloons to fill the gaps in the US weather-observing network, which has recently been downsized by the Trump administration.
Spanish Armada-era astrolabe returns to Scilly after mysterious global journey
It spent hundreds of years languishing on the seabed off the Isles of Scilly in the far south-west of Britain before being hauled back to the surface by divers and setting off a circumnavigation of the world.Finally the Pednathise Head astrolabe – a rare example of a 16th-century navigational instrument once used by sailors to determine latitude – is back on Scilly after being rediscovered on the other side of the Atlantic.It turns out that after being sold and leaving the UK, the astrolabe passed through private collections in Australia and the US, its true identity forgotten along the way, before ending up in a museum on the Florida Keys.“It’s been on quite a journey,” said Xavier Duffy, the curator of the Isles of Scilly Museum. “We’re thrilled to have it back on Scilly and in the care of the museum
My Cultural Awakening: I moved across the world after watching a Billy Connolly documentary
I was 23 and thought I had found my path in life. I’d always wanted to work with animals, and I had just landed a job as a vet nurse in Melbourne. I was still learning the ropes, but I imagined I would stay there for years, building a life around the work. Then, five months in, the vet called me into his office and told me it wasn’t working out. “It’s not you,” he said, “I just really hate training people

The Guide #217: The Louvre heist seems straight out of a screenplay – no wonder on-screen capers have us gripped
It was like something out of a movie. On the morning of 19 October, news broke of a heist at the Louvre in Paris: four thieves, disguised as construction workers, had made off with eight “priceless” pieces of French crown jewels from the 19th century. They also took a crown that once belonged to Empress Eugénie, wife of Napoleon III, but for some reason dropped it outside the museum. The haul has since been valued by a prosecutor at around €88m.The details of the case are astonishing, from the robbery itself – the thieves arrived in broad daylight, using a truck with a mechanical ladder to access the targeted gallery’s window, which they cut through with power tools – to subsequent revelations about the museum’s security measures
Seth Meyers on Trump: ‘The most unpopular president of all time’
Seth Meyers spoke about rising tensions within the Republican party with Donald Trump losing support from his base over the Jeffrey Epstein scandal.The Late Night host spoke about yesterday’s dramatic meeting in the situation room to discuss Epstein, an ongoing crisis that has seen the president becoming “wildly unpopular”.Meyers said that Trump is “by all the accounts the most unpopular president of all time” and up until this point has only been “able to hang on to power because he has a tight grip on the Republican party no matter what he did or how bad things got”.But a new poll shows that only 33% of American adults approve of how the president is managing the government, a figure that’s down from March with the fall driven by Republicans or independents.Meyers called this “a meaningful and real development” and “it’s not coming out of thin air” with Trump “pissing off Maga” in multiple ways
Colbert on Trump and Epstein: ‘They were best pals and underage girls was Epstein’s whole thing’
Late-night hosts covered this week’s latest bombshell Epstein and Trump revelations and spoke about the president’s latest interview with Laura Ingraham.On The Late Show, Stephen Colbert spoke about the government shutdown likely coming to an end after “an historic impasse” (the shutdown later did end) and Democrat Adelita Grijalva being sworn in as a member of Congress, seven weeks after she won a special House election in Arizona.Colbert said she has been “reborn from the ashes” and will be the 218th and final signature needed to force a vote to release the Jeffrey Epstein files.He joked that on her first day she was shown around and told “down there is the room where you’re going to topple the pervert cabal”.This week saw some new emails from Epstein released which suggest Trump knew of his conduct
