As Developing Cyclone Melissa was churning off the coast of Haiti, weather expert Philippe Papin had confidence it would soon grow into a monster hurricane.
Serving as primary meteorologist on duty, he forecasted that in a single day the weather system would intensify into a category 4 hurricane and start shifting in the direction of the coast of Jamaica. Not a single expert had ever issued this confident forecast for rapid strengthening.
But, Papin had an ace up his sleeve: artificial intelligence in the form of the tech giant’s new DeepMind hurricane model – launched for the initial occasion in June. True to the forecast, Melissa did become a storm of remarkable power that ravaged Jamaica.
Meteorologists are heavily relying upon the AI system. During 25 October, Papin explained in his official briefing that the AI tool was a primary reason for his certainty: “Approximately 40/50 AI simulation runs show Melissa reaching a most intense storm. While I am unprepared to predict that intensity at this time given track uncertainty, that is still plausible.
“There is a high probability that a phase of rapid intensification will occur as the storm moves slowly over very warm sea temperatures which is the highest marine thermal energy in the entire Atlantic basin.”
The AI model is the pioneer AI model focused on tropical cyclones, and currently the first to outperform standard weather forecasters at their specialty. Through all 13 Atlantic storms this season, Google’s model is top-performing – even beating human forecasters on track predictions.
The hurricane eventually made landfall in Jamaica at category 5 strength, among the most powerful coastal impacts recorded in nearly two centuries of record-keeping across the region. The confident prediction likely gave people in Jamaica additional preparation time to get ready for the disaster, potentially preserving people and assets.
The AI system works by spotting patterns that conventional time-intensive physics-based prediction systems may miss.
“They do it far faster than their physics-based cousins, and the computing power is more affordable and demanding,” stated Michael Lowry, a former meteorologist.
“What this hurricane season has proven in quick time is that the recent AI weather models are competitive with and, in certain instances, superior than the less rapid traditional forecasting tools we’ve traditionally leaned on,” he added.
To be sure, the system is an instance of machine learning – a method that has been employed in research fields like meteorology for a long time – and is not generative AI like ChatGPT.
AI training processes mounds of data and pulls out patterns from them in a manner that its model only requires minutes to generate an answer, and can do so on a desktop computer – in strong contrast to the primary systems that authorities have utilized for years that can take hours to process and need the largest high-performance systems in the world.
Still, the fact that Google’s model could outperform previous top-tier traditional systems so rapidly is truly remarkable to meteorologists who have spent their careers trying to predict the world’s strongest weather systems.
“I’m impressed,” said James Franklin, a former expert. “The sample is now large enough that it’s pretty clear this is not a case of chance.”
Franklin said that while Google DeepMind is beating all competing systems on predicting the trajectory of storms worldwide this year, like many AI models it sometimes errs on extreme strength forecasts wrong. It struggled with Hurricane Erin earlier this year, as it was similarly experiencing quick strengthening to category 5 above the Caribbean.
During the next break, Franklin stated he intends to talk with the company about how it can make the AI results more useful for experts by offering extra internal information they can use to assess the reasons it is coming up with its answers.
“The one thing that nags at me is that while these forecasts seem to be really, really good, the results of the model is kind of a black box,” remarked Franklin.
Historically, no a commercial entity that has produced a top-level weather model which grants experts a peek into its techniques – in contrast to most systems which are offered free to the public in their entirety by the authorities that designed and maintain them.
The company is not the only one in adopting artificial intelligence to solve difficult meteorological problems. The US and European governments also have their own artificial intelligence systems in the development phase – which have also shown improved skill over previous traditional systems.
Future developments in artificial intelligence predictions appear to involve new firms taking swings at formerly tough-to-solve problems such as long-range forecasts and better advance warnings of tornado outbreaks and flash flooding – and they are receiving US government funding to do so. A particular firm, WindBorne Systems, is also deploying its own weather balloons to fill the gaps in the US weather-observing network.
