Computer Vision For Weather Prediction

What is Computer Vision for Weather Prediction?

Computer vision for weather prediction refers to the application of AI-driven image processing techniques to analyze meteorological data, such as satellite imagery, radar scans, and ground-based observations. Unlike traditional methods that rely heavily on numerical models and statistical analysis, computer vision focuses on extracting patterns, anomalies, and trends from visual data. This approach enables faster and more accurate predictions, especially for localized weather events like thunderstorms, hurricanes, and heatwaves.

At its core, computer vision uses deep learning algorithms, particularly convolutional neural networks (CNNs), to process and interpret images. These algorithms can identify cloud formations, track storm movements, and even predict precipitation levels by analyzing pixel-level details. The result is a more dynamic and responsive weather prediction system that adapts to real-time changes.
