Forecasting the Weather Using Quantum Computers

Every year there are hurricanes, extreme heat waves, tornadoes, and other extreme weather events, resulting in thousands of deaths and billions of dollars in damages. Prediction of extreme weather further in advance and with increased accuracy could allow for targeted regions to be better prepared in order to reduce loss of life and property damage.

Granted, there has been much work undertaken in the development of sophisticated computational models to improve forecasting over the years, and much progress has been made. Weather forecasting requires analyzing huge amounts of data containing several dynamic variables, such as air temperature, pressure, and density that interact in a non-trivial way. However, there are limitations to using classical computers–even supercomputers–in developing numerical weather and climate prediction models.1 Also, the process of analyzing the weather data by traditional computers may not be fast enough to keep up with ever-changing weather conditions.2

Even local weather forecasting, which is rapidly evolving all the time, can stand to benefit from improved forecasting. Take, for example, thunderstorms, where highly accurate and advanced prediction by improved data analysis could minimize the resulting damage, as there could be warning further in advance about potential power outages, and increased preparedness, allowing the local community to restore power faster.3 So, then, how can weather forecasting be improved on both the local and global scale?

Quantum computing has the potential to improve conventional numerical methods to boost tracking and predictions of meteorological conditions by handling huge amounts of data containing many variables efficiently and quickly, by harnessing the computing power of qubits,4 and by using quantum-inspired optimization algorithms.5 Moreover, pattern recognition, crucial for understanding the weather, can be enhanced by means of quantum machine learning.1, 2

In fact, the enhancement of weather forecasting by means of quantum computing is set to become a reality in the not so distant future. Already, a company involved in cutting-edge weather forecasting using supercomputers is unveiling a quantum computer for commercial use that can tackle problems that occur outside of the lab.6 Developments in such technology may eventually be suitable for weather prediction.

Quantum computing will serve to benefit weather forecasting on both the local scale as well as on a grander scale for more-advanced and accurate warning of extreme weather events, potentially saving lives and reducing property damage annually.
