Numerical weather prediction (NWP) has played a crucial role in economic planning and saving lives through accurate weather forecasts. Improvements in computational power, parameterization, and data assimilation have enhanced weather forecasting. Data-driven deep learning models have gained popularity due to their low processing costs and ability to generate large ensembles. However, these models must improve their resolution to effectively capture small-scale phenomena. Researchers have developed FourCastNet, a high-resolution Fourier-based neural network forecasting model, which offers several improvements to data-driven weather forecasting, including accurate forecasts of surface winds and precipitation, higher resolution than current models, and the ability to generate large ensembles with well-calibrated uncertainties.
Introducing FourCastNet: A Game-Changing Data-Driven Weather Forecasting Model
In today’s world, accurate weather predictions are crucial for industries such as transportation, logistics, agriculture, and energy production. Improved weather forecasting can save lives and help with economic planning. Traditional numerical weather prediction (NWP) models have made significant progress over the years, but they still have limitations.
Data-driven Deep Learning (DL) models are emerging as a popular alternative to NWP models. These DL models offer several advantages, including lower processing costs and the ability to generate large ensembles for probabilistic forecasting and data assimilation. They can address biases in NWP models and provide faster and more accurate forecasts.
However, most data-driven weather models are trained on low-resolution data, which can lead to a loss of important fine-scale physical information. To be truly effective, data-driven models need to provide forecasts with the same or better resolution as state-of-the-art NWP models. High-resolution models can capture small-scale dynamics and accurately predict extreme weather events like tropical cyclones.
Researchers from NVIDIA Corporation, Lawrence Berkeley, Rice University, University of Michigan, California Institute of Technology, and Purdue University have developed FourCastNet, a Fourier-based neural network forecasting model. It produces global data-driven forecasts of atmospheric variables at a resolution of 0.25, which is comparable to the high-resolution Integrated Forecasting System (IFS) model.
Four Novel Improvements Offered by FourCastNet:
- Accurate forecasting of difficult variables like surface winds and precipitation for up to one week. This is a significant advancement, as these variables have been challenging to forecast accurately on a global scale using DL models. This improvement has implications for wind energy planning and disaster mitigation.
- Eight times higher resolution than cutting-edge DL-based global weather models. FourCastNet can accurately resolve severe weather events like tropical cyclones and atmospheric rivers, which were challenging for earlier DL models due to coarser grids. This high resolution improves precision.
- Comparable predictions to the IFS model for lead periods of up to three days and significantly outperforming the IFS model for lead periods of up to a week. FourCastNet, driven by data alone, demonstrates the potential of data-driven modeling to replace and supplement NWP models, which rely on decades of development and physics-based principles.
- The ability to generate large ensembles, providing well-calibrated and constrained uncertainties in extreme weather forecasts. With 1,000-member ensembles, FourCastNet improves the accuracy of early warnings and enables rapid evaluation of the effects of extreme weather events.
Achieving these advancements in weather forecasting through FourCastNet can revolutionize the way businesses plan and prepare for weather-related challenges. By leveraging AI technology and data-driven modeling, companies can stay competitive, make informed decisions, and enhance their operations.
