When Developing Cyclone Melissa was churning off the coast of Haiti, weather expert Philippe Papin felt certain it would soon escalate to a major tropical system.
Serving as primary meteorologist on duty, he predicted that in just 24 hours the weather system would become a severe hurricane and start shifting towards the Jamaican shoreline. No forecaster had ever issued such a bold prediction for rapid strengthening.
However, Papin possessed a secret advantage: AI technology in the guise of Google’s recently introduced DeepMind cyclone prediction system – released for the initial occasion in June. And, as predicted, Melissa evolved into a system of remarkable power that ravaged Jamaica.
Meteorologists are heavily relying upon Google DeepMind. During 25 October, Papin explained in his official briefing that the AI tool was a primary reason for his confidence: “Roughly 40/50 Google DeepMind ensemble members show Melissa reaching a most intense storm. While I am unprepared to predict that intensity yet given path variability, that remains a possibility.
“It appears likely that a phase of quick strengthening will occur as the storm moves slowly over exceptionally hot sea temperatures which is the most extreme oceanic heat content in the whole Atlantic basin.”
The AI model is the pioneer artificial intelligence system dedicated to hurricanes, and currently the first to beat standard weather forecasters at their own game. Through all tropical systems this season, Google’s model is the best – even beating experts on path forecasts.
The hurricane ultimately struck in Jamaica at category 5 strength, one of the strongest landfalls ever documented in almost 200 years of data collection across the region. The confident prediction probably provided residents additional preparation time to prepare for the catastrophe, possibly saving lives and property.
The AI system works by identifying trends that conventional time-intensive physics-based prediction systems may miss.
“They do it much more quickly than their traditional counterparts, and the processing requirements is less expensive and time consuming,” stated Michael Lowry, a ex meteorologist.
“What this hurricane season has demonstrated in quick time is that the newcomer AI weather models are on par with and, in certain instances, superior than the slower physics-based forecasting tools we’ve relied upon,” he added.
To be sure, the system is an instance of AI training – a method that has been employed in data-heavy sciences like weather science for years – and is not creative artificial intelligence like ChatGPT.
Machine learning takes mounds of data and pulls out patterns from them in a manner that its system only takes a few minutes to generate an result, and can operate on a desktop computer – in strong contrast to the flagship models that governments have used for years that can take hours to run and need the largest supercomputers in the world.
Nevertheless, the fact that Google’s model could exceed previous top-tier legacy models so rapidly is truly remarkable to meteorologists who have spent their careers trying to predict the most intense weather systems.
“It’s astonishing,” said James Franklin, a retired expert. “The data is now large enough that it’s pretty clear this is not a case of beginner’s luck.”
Franklin noted that while the AI is beating all other models on forecasting the future path of hurricanes worldwide this year, like many AI models it occasionally gets high-end intensity forecasts inaccurate. It struggled with Hurricane Erin previously, as it was also undergoing quick strengthening to category 5 north of the Caribbean.
During the next break, he stated he intends to talk with the company about how it can enhance the DeepMind output more useful for experts by providing additional internal information they can utilize to evaluate the reasons it is producing its conclusions.
“A key concern that nags at me is that while these forecasts appear really, really good, the results of the system is essentially a opaque process,” remarked Franklin.
There has never been a private, for-profit company that has developed a high-performance weather model which grants experts a view of its techniques – in contrast to nearly all systems which are provided at no cost to the general audience in their full form by the governments that created and operate them.
The company is not the only one in starting to use AI to address challenging meteorological problems. The US and European governments are developing their own AI weather models in the works – which have also shown improved skill over earlier traditional systems.
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 improved advance warnings of severe weather and sudden deluges – and they have secured US government funding to do so. A particular firm, WindBorne Systems, is also deploying its own atmospheric sensors to fill the gaps in the national monitoring system.
