AI and ML for Weather Prediction: Concepts and Tools
🔍 Introduction
Weather prediction has traditionally relied on physics-based numerical models. However, these models are computationally intensive and sometimes limited by data availability and resolution. In recent years, Artificial Intelligence (AI) and Machine Learning (ML) have emerged as powerful alternatives or complements to traditional forecasting methods.
📘 Key Concepts
1. Artificial Intelligence (AI)
AI refers to systems or machines that mimic human intelligence. In weather forecasting, AI can process large datasets, learn patterns, and make predictions without being explicitly programmed with physical models.
2. Machine Learning (ML)
ML is a subset of AI that uses statistical techniques to enable systems to learn from data. ML algorithms are trained on historical weather data to predict future conditions.
3. Deep Learning (DL)
A subset of ML that uses neural networks with many layers to model complex patterns. Especially useful in processing satellite images, radar data, and spatiotemporal sequences in weather.
4. Time Series Forecasting
Most weather data is temporal. ML models like LSTM (Long Short-Term Memory) and GRU (Gated Recurrent Unit) are designed to handle time-dependent data.
5. Spatiotemporal Modeling
Weather varies across space and time. ML models are adapted to handle spatial data (grids, maps) and temporal sequences simultaneously.
6. Hybrid Models
Combining ML models with traditional Numerical Weather Prediction (NWP) models to correct biases or improve resolution.
