A weather satellite is an advanced orbiting spacecraft designed to observe and monitor Earth’s atmospheric conditions, weather patterns, and climate dynamics. Equipped with high-resolution cameras, infrared sensors, and other instruments, it captures real-time data on cloud formations, storm systems, temperature variations, wind speeds, and ocean currents. Positioned in geostationary or polar orbits, these satellites provide continuous imagery and measurements that meteorologists use to forecast weather, track hurricanes and typhoons, detect wildfires, and monitor environmental changes. By delivering accurate, global perspectives, weather satellites enhance disaster preparedness, aviation safety, and agricultural planning, playing a vital role in understanding and responding to our planet’s ever-changing climate.
