Satellites and radar are essential tools in modern meteorology, providing the critical data necessary for accurate weather prediction.1

Satellites

Meteorological satellites provide global, real-time observations that are vital for medium-range forecasting.2
* Polar Orbiters: These circle Earth at lower altitudes, providing high-resolution data for high-latitude regions.2
* Geostationary Satellites: Positioned above the Equator, they offer continuous monitoring of specific areas, which is invaluable for tracking the rapid development of hurricanes, thunderstorms, and weather fronts.23
* Data Collection: Sensors measure temperature, moisture, and cloud distributions, helping meteorologists estimate storm intensity and location.23

Radar

Radar allows forecasters to "see" precipitation and monitor storm evolution in real time.4
* Storm Tracking: Radar is used to monitor the growth and motion of severe weather, such as tornadoes and thunderstorms.4
* Doppler Technology: Modern Doppler radar detects frequency shifts to calculate wind speeds and directions, identifying dangerous phenomena like microbursts and wind shear.45
* Wind Profiling: Specialized radar systems can detect winds even in clear air, providing continuous data that complements traditional balloon-based observations.45
