As Tropical Storm Melissa was churning off the coast of Haiti, meteorologist Philippe Papin felt certain it was about to grow into a major tropical system.
Serving as primary meteorologist on duty, he forecasted that in just 24 hours the storm would become a severe hurricane and begin a turn in the direction of the coast of Jamaica. No forecaster had previously made such a bold prediction for quick intensification.
However, Papin possessed a secret advantage: AI technology in the form of the tech giant’s new DeepMind hurricane model – released for the first time in June. And, as predicted, Melissa did become a system of astonishing strength that tore through Jamaica.
Meteorologists are increasingly leaning hard on the AI system. During 25 October, Papin clarified in his public discussion that the AI tool was a primary reason for his certainty: “Approximately 40/50 AI ensemble members indicate Melissa reaching a most intense hurricane. Although I am unprepared to forecast that strength yet due to track uncertainty, that remains a possibility.
“It appears likely that a phase of quick strengthening will occur as the system moves slowly over exceptionally hot sea temperatures which is the highest marine thermal energy in the whole Atlantic basin.”
Google DeepMind is the pioneer AI model dedicated to hurricanes, and currently the first to beat traditional meteorological experts at their specialty. Across all tropical systems this season, the AI is the best – even beating experts on path forecasts.
The hurricane eventually made landfall in Jamaica at maximum intensity, one of the strongest coastal impacts ever documented in almost 200 years of record-keeping across the Atlantic basin. Papin’s bold forecast probably provided residents extra time to prepare for the catastrophe, potentially preserving people and assets.
The AI system works by spotting patterns that traditional lengthy physics-based prediction systems may miss.
“The AI performs much more quickly than their physics-based cousins, and the computing power is less expensive and demanding,” stated Michael Lowry, a former forecaster.
“What this hurricane season has proven in short order is that the newcomer artificial intelligence systems are competitive with and, in some cases, superior than the less rapid traditional weather models we’ve traditionally leaned on,” he said.
To be sure, Google DeepMind is an example of machine learning – a method that has been employed in data-heavy sciences like meteorology for years – and is distinct from creative artificial intelligence like ChatGPT.
Machine learning takes mounds of data and pulls out patterns from them in a such a way that its model only requires minutes to generate an answer, and can do so on a standard PC – in sharp difference to the primary systems that authorities have used for decades that can require many hours to process and require some of the biggest high-performance systems in the world.
Still, the reality that the AI could outperform earlier gold-standard legacy models so quickly is truly remarkable to weather scientists who have dedicated their lives trying to predict the most intense storms.
“I’m impressed,” commented James Franklin, a former forecaster. “The sample is sufficient that it’s pretty clear this is not a case of beginner’s luck.”
He said that although the AI is outperforming all other models on forecasting the trajectory of hurricanes worldwide this year, similar to other systems it sometimes errs on high-end intensity predictions inaccurate. It had difficulty with Hurricane Erin previously, as it was similarly experiencing rapid intensification to maximum intensity north of the Caribbean.
During the next break, he stated he plans to talk with the company about how it can enhance the AI results more useful for forecasters by offering extra internal information they can use to evaluate the reasons it is producing its answers.
“The one thing that troubles me is that although these forecasts seem to be highly accurate, the results of the system is kind of a opaque process,” remarked Franklin.
Historically, no a commercial entity that has developed a top-level weather model which grants experts a peek into its techniques – in contrast to most systems which are provided at no cost to the general audience in their full form by the authorities that created and operate them.
Google is not alone in adopting AI to address challenging weather forecasting problems. The US and European governments are developing their own artificial intelligence systems in the works – which have demonstrated improved skill over previous traditional systems.
Future developments in artificial intelligence predictions seem to be new firms taking swings at formerly difficult problems such as sub-seasonal outlooks and better early alerts of severe weather and flash flooding – and they are receiving federal support to do so. One company, WindBorne Systems, is even launching its proprietary atmospheric sensors to address deficiencies in the US weather-observing network.
