Breakdown of AI Systems in Weather Forecasting

AI systems used in weather forecasting employ predefined rules to simulate the decision-making ability of human meteorologists. These systems can interpret weather data and generate forecasts by applying rules derived from human expertise. They act as digital assistants, helping meteorologists make more informed decisions by automating routine analysis and focusing on complex interpretations.

Machine Learning (ML)

Machine learning algorithms analyze historical weather data to identify patterns and make predictions. For instance, regression models can predict temperature or rainfall based on past data. ML can also be used to improve the accuracy of existing weather models by learning from the discrepancies between predicted and observed weather. By continuously updating their knowledge base, these algorithms refine their predictions over time, becoming more reliable and accurate.

Examples:

• Regression Models: Predict temperature or rainfall based on historical data. These models identify trends and relationships between different weather variables.
• Classification Algorithms: Distinguish between different types of weather phenomena, such as clear skies, rain, or thunderstorms, by learning from labeled data.

Neural Networks

Neural networks can model complex, non-linear relationships in weather data. For example, a neural network could be trained on historical weather data to predict the likelihood of severe weather events, such as hurricanes or tornadoes. These networks can capture the intricate dependencies between different weather variables better than traditional statistical methods, enabling more precise and nuanced forecasts.

Examples:

• Predicting Severe Weather Events: Neural networks can model complex, non-linear relationships in weather data to predict events like hurricanes or tornadoes. They learn from historical patterns and improve their predictions over time
• Temperature and Precipitation Forecasting: Neural networks can accurately predict daily temperature ranges and precipitation levels by analyzing past weather data and current atmospheric conditions.

Deep Learning

Deep learning models, such as convolutional neural networks (CNNs), can analyze satellite images to detect and track weather patterns. These models can identify cloud formations, storms, and other meteorological phenomena with high accuracy. Recurrent neural networks (RNNs) can also be used to make sequential predictions, such as forecasting weather over several days based on current conditions and historical data. These deep learning techniques are particularly valuable for understanding and predicting dynamic weather systems.

Examples:

• Convolutional Neural Networks (CNNs): Analyze satellite images to detect and track weather patterns. CNNs can identify cloud formations, storms, and other meteorological phenomena with high accuracy.
• Recurrent Neural Networks (RNNs): Make sequential predictions, such as forecasting weather over several days based on current conditions and historical data. RNNs are effective at capturing temporal dependencies in weather data.

• Black Box Problem: The decision-making process of AI models can be opaque, making it difficult to understand how outputs are determined. This lack of transparency can be a barrier to trust and acceptance among meteorologists and decision-makers.

The Advantages of Incorporating AI with NWP Forecasting

While AI and NWP models may have their shortcomings alone, together they significantly enhance weather forecasting in several ways. For example, as Climavision’s Chief NWP Scientist Peter Childs explained to Middle Tech Podcast’s Logan Jones, while AI may not be able to understand physics alone, it can help advance NWP modeling by uncovering better parameterizations.

Climavision uses cutting edge AI technology to its fullest extent to create AI models like our Horizon AI Subseasonal to Seasonal model as well as bolstering the speed and accuracy of our NWP models Horizon AI Global, Pointand HIRES. With AI and NWP expertise combined, Climavision can offer the entire timescale horizon of forecasting from real time radar coverage to long term forecasts as much as two years out. From data assimilation and quality control to generating hundreds of ensemble forecasts, we have incorporated AI into every step of the forecasting process so that we can deliver forecasts tailored to specific use cases with greater speed and verified accuracy.

Enhanced Forecast Accuracy

AI algorithms analyze vast datasets from satellites, weather stations, and other sensors to identify patterns and trends. By refining predictive models, AI leads to more accurate weather forecasts. For example, AI can improve the accuracy of temperature, precipitation, and wind predictions by learning from NWP models and continuously updating based on new information.

Factors influencing the accuracy of AI forecasts include the quality of data, the sophistication of the AI model and its training, and the specific weather phenomena being predicted. High-quality, diverse datasets and advanced models are crucial for achieving accurate predictions. Moreover, AI’s ability to learn and adapt from past performance helps improve forecast accuracy over time.

Climavision is pushing the envelope of accuracy across our entire Horizon AI Forecasting suite. For example, our Horizon AI S2S model is 30% more accurate globally and 100% more accurate for specific locations versus the ECMWF. The improved accuracy is due to our S2S model being fueled by decades of back testing data, training on millions of observations plus proprietary climate simulations, and being informed on 500 different ensembles. Additionally, Climavision ensures the Horizon AI S2S model avoids the black box problem by producing forecasts that are explainable based on easily interpretable neural networks developed entirely in-house.

But don’t take out word for it, see for yourself. We have built a fast, easy to use API for our Horizon AI S2S model that you can access to see accuracy metrics (CRPSS, ACC and MAE) for past forecasts as well as a back tested forecast (i.e., what our forecast would have been if you queried it on this day) and the observed weather, for a particular latitude and longitude pair, or for a global forecast. Read the API documentation here.

Data Analysis and Integration for NWP models

AI algorithms not only help with AI weather models, but they also benefit NWP models as well. AI systems excel at processing and analyzing large volumes of data from various sources, such as weather satellites, weather stations, and ocean buoys. AI algorithms can integrate and interpret this vast amount of data, identifying patterns and correlations that humans might overlook. By integrating different data sources, AI improves the overall accuracy of weather models.

At Climavision, we are leveraging AI algorithms to process and analyze vast amounts of data to integrate more than 1.5 billion global observational datasets daily into our NWP models. These datasets come from novel sources such as space-based datasets. The ability to utilize these novel, massive datasets give our partners more insight into what is happening, even in remote areas in real time. In fact, through our meticulous data processing and rigorous quality control measures, we elevate the usable observational data to over 20%, a stark contrast to the mere 3% provided by government sources. The more data there is to input into weather models, the more accurate the model outputs will be.

Not Just Any AI Will Do

Artificial Intelligence has revolutionized the accuracy and efficiency of weather data and forecasting, benefiting numerous industries. Accurate predictions enable early warnings and preparedness for severe weather events, protecting lives and property. But not all AI weather forecasting is made equal. It’s important to consider the following:

• Is the AI-generated weather forecast available now? While some companies have recently announced new AI capabilities, they don’t have any forecasts available for the market.
• If they are available, how much more accurate are the AI forecasts than government model forecasts?
• How are the AI forecasts accuracy verified and how often?
• Are the forecasts probabilistic so that you can see the entire range of possibilities with their associated likelihoods?
• Are the forecasted results of the AI model explainable so that you can easily determine how the forecast reached those conclusions?
