Track active weather with NOAA’s new radar viewer
Dec 17, 2020 · NOAA’s new interactive radar viewer webpage with expanded radar data will allow you to observe the type and movement of precipitation falling from the sky. Looking at several radar images over a period of time — or a radar loop — can offer clues about where and how fast the rain or snow is falling.
List of radar types - Wikipedia
Search radars scan great volumes of space with pulses of short radio waves. They typically scan the volume two to four times a minute. The waves are usually less than a meter long. Ships and planes are metal, and reflect radio waves.
Radar - Wikipedia
Radar is a system that uses radio waves to determine the distance (ranging), direction (azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method [1] used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain.
Next Generation Weather Radar (NEXRAD) | National Centers for ...
Aug 21, 2024 · This product provides information about the state (frozen, melting, or fully liquid) of precipitation at different altitudes in a particular area. This product is generated for each elevation angle that the radar scans and can be particularly useful …
How radar works - National Oceanic and Atmospheric Administration
As the name implies, radars use radio waves to determine the distance and velocity of the targets they hit. A radar system usually consists of a transmitter to send out radio signals and a receiver to catch any reflected energy from targets.
RADAR Basics - National Weather Service
The "E" scan, also called "RHI" (range height indicator), displays the radar targets in both range from the radar and height above the earth. Like the PPI, the RHI "sweep" rotates vertically in coincidence with the movement of the radar antenna angle.
Area Radars - National Weather Service
National Weather Service radars provide forecasters information on precipitation intensity and movement (direction and speed). Dual polarization technology adds new information about the size and shape of an object, which will improve estimates of how much rain is falling, improving flash flood detection and warnings.
