    Well now you have me wanting to look again, but as I understand it, there are no physical equations involved like our current computer models. It’s learning from ERA data sets from the past and final outcomes. 

    Really easy to find.

    https://weathersats.com/the-evolution-and-future-of-ai-in-weather-forecasting/#:~:text=AI Models Enhancing Numerical Weather,forecasts more frequently and accurately.

    Normalization and Formatting: Data, often in GRIB or NetCDF formats, is cleaned and structured into consistent grids, frequently at 0.25-degree resolution.

    Feature Engineering: Raw data is converted into actionable features, such as calculating "feels like" temperature or creating precipitation intensity categories. 

    Data Assimilation for "Real-Time" Updates

    AI models use advanced techniques to ingest the current state of the atmosphere into the model to begin a forecast: 

    AI-Driven Assimilation: Instead of traditional, slow numerical methods, AI accelerates the integration of new observations by filling in data gaps in regions where measurements are sparse.

    Hybrid Approaches: Some models, such as NeuralGCM, blend AI with traditional physical simulations to ensure the input data respects atmospheric dynamics.

    Specialized Adapters: To shift from historical training data to live data, models may use specialized neural network architectures (like U-Net) to map real-time, "messy" data into the same format used for training. 

    Key Technologies Used

    Neural Networks (CNNs/RNNs): Convolutional Neural Networks analyze spatial satellite imagery, while Recurrent Neural Networks process time-series data.

    Cloud Platforms: Models are often hosted on AWS, Google Cloud, or Microsoft Azure to manage the high volume of data.

    Transformers: Used to process long-range dependencies in atmospheric data.

    You have “If bringing my juju back”…I think you mean “I’m” bringing my juju back…right? Correct that so the snow gods don’t punish us for poor grammar..please:lol:

    I remember when people complained about the Juju word back on Eastern. Lol

    There was no Grinch storm instead its a Christmas miracle. Festivus for the rest of us.
