Understanding the Evolution of Weather Forecasting​

Taking a step back to consider the historical context sheds light on why weather forecasts have traditionally been presented in a format that leaves much to the user's interpretation. Initially, weather information reached the public through newspapers and later, television news—mediums that, by necessity, catered to a general audience. This one-size-fits-all approach meant delivering raw data and leaving individuals to make sense of what that meant for their daily lives. It was a manual process, but within the constraints of the time, it worked.

With the advent of mobile technology, access to weather forecasts has dramatically expanded. Today, it's hard to find a smartphone without a weather app. Yet, this digital transition has mostly replicated the old models of presentation, focusing on visual enhancements and location flexibility but still providing data in its raw, uninterpreted form. This approach overlooks the transformative potential of digital platforms to provide contextual, actionable insights tailored to specific needs.

ClimaLinks is challenging this status quo by redefining the final mile of weather forecasting. ClimaLinks envisions a future where weather data isn't just accurate but is indispensable for forward-thinking strategies and operations. Our mission is to transform weather data from a mere reference to an active decision-making tool, enabling businesses to adopt a proactive approach.

No longer is weather information a mere icon on your screen indicating it's sunny and 16°C. ClimaLinks integrates weather insights directly into your planning tools, making it an indispensable part of decision-making processes rather than an afterthought.

Beyond Precision: Marrying Accuracy with Usability in Weather Forecasting​

It should still, however, be emphasized that the weather forecasting industry has witnessed impressive innovation, particularly in improving forecast accuracy. Teams from world-renowned universities and major agencies like NOAA, and ECMWF have made significant strides, and recently, private sector giants like Google, NVIDIA, and Microsoft have joined the fray with their cutting-edge AI models (check out our previous blog). These models, such as Google's Graphcast and NVIDIA's FourCastNet, are competing to deliver forecasts that are not just accurate but incredibly rapid, producing results thousands of times faster than traditional methods.

Yet, this rapid innovation has largely centered on one half of the forecasting coin: accuracy. The other side, usability, remains an area less trodden. Historically, when the bottleneck was forecast accuracy, this focus was justified. But now, as we find ourselves awash in high-quality forecasts that can reliably predict weather days in advance, we must address the other challenge. It's no longer just about having accurate data; it's about making that data work for us in the most efficient and practical ways possible.

Mapping the Future of Meteorology: AI-driven Innovations by Google, NVIDIA, Microsoft, and Huawei Redefine Weather Prediction (AI-generated Image by OpenAI)

You might have recently seen that Google is making strides in AI-driven weather forecasting with their Graphcast model. But did you know that many other large tech companies are also entering the scene? In this article, we dive into the advancements in AI meteorology innovations from the private sector, putting a spotlight on key players like NVIDIA's FourCastNet, Microsoft's ClimaX, and Huawei's Pangu-Weather and exploring how these technologies have the potential to revolutionize the field of meteorological science.

🎯 AI Methods in Weather Forecasting: Same Goal, Different Approaches​

The quest for the most effective AI method in weather forecasting is a dynamic and ongoing challenge. While Google has been one of the frontrunners with models like Graphcast and Met-Net-3, the industry is witnessing a variety of innovative approaches by other tech giants.

Google's Graphcast and Met-Net-3​

Graphcast excels in providing rapid and accurate weather predictions. This model distinguishes itself with forecasts that extend up to 10 days into the future, demonstrating a resolution accuracy of about 28x28 km at the equator. While Graphcast is adept at short to medium-range forecasts, it encounters challenges in enhancing resolution and sustaining accuracy for longer forecast periods. In contrast, Met-Net-3, another innovative model from the same team, specializes in high-resolution forecasting. This model is capable of delivering forecasts with an impressive 1x1 km resolution, offering updates every few minutes. Its forte lies in its precision, although it primarily focuses on short-term forecasting, with a lead time of just 24 hours. For in-depth insights, visit Google's official Graphcast blog and Met-Net-3 blog. For the scientific paper on Graphcast, see here.

Technical Reading on Google's Graph Neural Network (GNN)

• Approach: Google's GraphCast, developed by DeepMind, uses Graph Neural Networks (GNNs) for weather forecasting, focusing on spatially structured data.

• Notable Strengths: It provides rapid and precise weather predictions, while being a relatively small model (36.7 million parameters). This is significant as a 10-day forecast can be run in under a minute on relatively basic infrastructure (in their study, they use a TPU v4 device).

• Notable Limitations: Because the training data is ERA5 with a resolution of 0.25 degrees, this may produce challenges when trying to increase the resolution (such as to sub-km). Uncertainty is also handled by "spatially blurring" the forecasts, which becomes an important constraint at longer lead times (e.g., forecasting several days into the future).

NVIDIA's FourCastNet​

FourCastNet's strength lies in its exceptional speed, processing forecasts much faster than traditional models. Its current limitation is in sometimes producing results that deviate from established physical laws, a gap NVIDIA aims to bridge with future enhancements. Explore more on NVIDIA's official blog. For the scientific paper on FourCastNet, see here.

Technical Reading on NVIDIA's Fourier-based neural network

• Approach: NVIDIA's model uses a Fourier-based neural network framework and runs on cuDNN-accelerated TensorFlow. It operates on NVIDIA GPUs, achieving high-speed computation (A100 GPU, similar to Chat GPT).

• Notable Strengths: It can process extensive ensemble forecasts rapidly, making it suitable for real-time applications. To put this into context, NVIDIA claims that they are "45,000 times faster than traditional NWP models" (source). This is especially useful when considering ensemble forecasts and detection of extreme events. They also expect to eventually train the FourCastNet to "predict weather on sub-km scales."

• Notable Limitations: Like many other purely data driven AI weather models, the output may not always strictly obey known physical laws (read: produces unrealist results). Noting this in their research paper, NVIDIA plans to incorporate "Physics-informed Machine Learning" methods in the future.

Microsoft's ClimaX​

ClimaX handles various datasets effectively, particularly in downscaling for local forecasts. It uses separate models for different forecast intervals, a limitation addressed by ClimaX-iter which allows iterative predictions, though this can affect long-term forecast accuracy. Learn more about their approach on Microsoft's ClimaX overview and access the scientific paper here.

Technical Reading on Microsoft's Vision Transformers (ViT)

• Approach: Microsoft's ClimaX employs a multi-dimensional image-to-image translation architecture based on Vision Transformers (ViT).

• Notable Strengths: It's designed to handle a wide variety of weather and climate modeling training data ("heterogeneous datasets spanning different variables, spatio-temporal coverage, and physical groundings"). Using a ViT method also allows for training the model on spatially-incomplete datasets. Notably, this method also works well for being able to downscale data to get more localized results.

• Notable Limitations: In ClimaX, each model instance is trained for a specific lead time, necessitating separate models for different forecasting intervals. ClimaX-iter addresses this by enabling iterative predictions over multiple lead times with a single model. This approach offers greater efficiency and scalability, but it compromises accuracy in longer-term forecasts due to error accumulation.

Huawei's Pangu-Weather​

Pangu-Weather stands out as one of the few models implementing a 3D Earth Specific Transformer architecture, a notable advancement in AI weather forecasting. This 3D approach is key to its accuracy, allowing the model to capture intricate atmospheric relationships. Its rapid forecasting capabilities are on par with NVIDIA's FourCastNet. However, the complexity of 3D data processing raises computational demands, which poses challenges for scalability and practical application. This mirrors the balance seen in advanced AI models like OpenAI's ChatGPT, where increased sophistication often comes with higher resource requirements. Learn more about their approach on Pangu-Weather's official page and access the scientific paper here.

Technical Reading on Pangu-Weather and Huawei's 3D Earth Specific Transformer (3DEST)

• Approach: This model uses a 3D Earth-Specific Transformer (3DEST) architecture to process complex 3D meteorological data.

• Notable Strengths: Pangu-Weather can produce forecasts extremely rapidly, suggesting that they are similar to NVIDIA's FourCastNet (i.e., 45,000 times faster than traditional numerical models). This means that forecasts can be done in "real-time" (i.e., second(s)). They also use a 3D deep neural network, which can be more accurate than 2D networks (i.e., NVIDIA's FourCastNet), as it can capture intrinsic relationship between different atmospheric levels.

• Notable Limitations: The primary challenge for the Pangu-Weather system, akin to advanced AI models like OpenAI's ChatGPT, lies in the trade-off between model sophistication and computational demands. As the system incorporates more complex 3D data and hierarchical algorithms for accuracy, it faces increased computational overhead, particularly in memory usage, which restricts the scalability and practical application of the technology.
