As Developing Cyclone Melissa was churning off the coast of Haiti, weather expert Philippe Papin had confidence it would soon escalate to a monster hurricane.
As the lead forecaster on duty, he forecasted that in a single day the weather system would intensify into a severe hurricane and begin a turn towards the Jamaican shoreline. Not a single expert had previously made this confident prediction for rapid strengthening.
However, Papin had an ace up his sleeve: artificial intelligence in the form of Google’s new DeepMind cyclone prediction system – released for the initial occasion in June. And, as predicted, Melissa evolved into a storm of astonishing strength that ravaged Jamaica.
Meteorologists are increasingly leaning hard on Google DeepMind. On the morning of 25 October, Papin clarified in his official briefing that the AI tool was a key factor for his confidence: “Approximately 40/50 AI ensemble members indicate Melissa becoming a Category 5 storm. While I am unprepared to forecast that intensity at this time due to track uncertainty, that remains a possibility.
“There is a high probability that a period of rapid intensification is expected as the storm drifts over very warm ocean waters which is the most extreme marine thermal energy in the whole Atlantic basin.”
The AI model is the pioneer AI model focused on hurricanes, and currently the first to beat traditional meteorological experts at their specialty. Through all tropical systems so far this year, Google’s model is top-performing – surpassing experts on track predictions.
The hurricane ultimately struck in Jamaica at maximum intensity, among the most powerful coastal impacts ever documented in almost 200 years of data collection across the region. Papin’s bold forecast probably provided residents additional preparation time to prepare for the disaster, possibly saving lives and property.
The AI system operates through spotting patterns that conventional lengthy physics-based prediction systems may overlook.
“They do it much more quickly than their traditional counterparts, and the processing requirements is more affordable and time consuming,” said Michael Lowry, a former meteorologist.
“What this hurricane season has demonstrated in short order is that the recent AI weather models are on par with and, in certain instances, more accurate than the slower physics-based weather models we’ve traditionally leaned on,” he added.
To be sure, the system is an example of AI training – a technique that has been used in research fields like meteorology for a long time – and is not creative artificial intelligence like ChatGPT.
Machine learning takes mounds of data and extracts trends from them in a such a way that its system only requires minutes to generate an answer, and can operate on a desktop computer – in strong contrast to the primary systems that authorities have used for years that can require many hours to process and need some of the biggest supercomputers in the world.
Nevertheless, the reality that Google’s model could exceed previous top-tier traditional systems so quickly is nothing short of amazing to meteorologists who have dedicated their lives trying to forecast the most intense weather systems.
“It’s astonishing,” said James Franklin, a former forecaster. “The sample is sufficient that it’s pretty clear this is not just chance.”
Franklin said that while the AI is beating all other models on forecasting the trajectory 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 rapid intensification to category 5 north of the Caribbean.
In the coming offseason, Franklin said he plans to discuss with Google about how it can make the AI results more useful for forecasters by providing additional under-the-hood data they can use to evaluate the reasons it is coming up with its conclusions.
“The one thing that nags at me is that while these predictions seem to be highly accurate, the results of the model is kind of a black box,” remarked Franklin.
Historically, no a commercial entity that has produced a high-performance forecasting system which allows researchers a view of its techniques – in contrast to nearly all other models which are offered free to the public in their full form by the authorities that created and operate them.
The company is not the only one in adopting AI to solve challenging meteorological problems. The US and European governments are developing their own AI weather models in the works – which have demonstrated improved skill over earlier non-AI versions.
Future developments in AI weather forecasts appear to involve new firms tackling formerly tough-to-solve problems such as long-range forecasts and better advance warnings of tornado outbreaks and flash flooding – and they have secured US government funding to do so. A particular firm, WindBorne Systems, is even deploying its proprietary weather balloons to address deficiencies in the national monitoring system.
