Why such a name? These radars are based on a Doppler effect, named after the Austrian physicist Christian Doppler, who described it in 1842. There are a few different types of radars with their own characteristics, but the main one is Doppler weather radars also called Pulse-Doppler radars.

Radar data is extremely important to ensure safety in settlements and industrial plants (such as hydropower plants) and to prevent property damage from extreme weather.īut it is important to keep in mind that although all services use data from the same radars and weather stations, their weather forecasts may differ. There are also private services.īased on this data, rescue and meteorological services in different countries inform the population about the necessary precautions. Some examples: US National Oceanic and Atmospheric Administration ( NOAA), Met Office UK, Meteorological Service of Canada. The data from live weather radars is used for daily monitoring not only in potentially dangerous regions but also around the world by government organizations, that collect and process meteorological data in their forecasts and research. So the interactive radar is crucial to making accurate real-time “now cast” weather forecasts of precipitation. Radar processor - analyzes the radar data.The radar itself consists of the following main components: In general, if you see such a thing in a field - do not be alarmed, this is not an alien base. There is usually a small building near the radar, where employees monitor the health and operation of the radar. Its radius of action in the atmosphere is on average 200-250 kilometers.
There is a huge ball at the top of the radar - this is a shelter for the antenna that is inside. Typical radar is a four-story building size. The first weather radars appeared in the 1950s in the United States and Canada. It is formed from the abbreviation RADAR - Radio Detection And Ranging. The name "radar" appeared in the early 1940s. It also allows you to observe the devastating path of storms. Wind radars help to detect tornadoes and accurately calculate when bad weather gets to a particular city or region. Weather radars can help measure wind speed, too. They are used to determine the location of water-bearing clouds and their trajectory, so they are indispensable for predicting heavy rains, thunderstorms, tornadoes, snowfalls, and other types of dangerous weather. The definition of weather radars and their purposeĪ weather radar is modern meteorological equipment. Let's take a closer look at what is weather radar, what they are for, how such radars work, and more. These radars help to predict rain and snow, and other precipitation, but also wind and extreme weather such as thunderstorms or tornadoes. But how is it possible?ĭata for these animated maps is obtained from weather radars located all around the world. Please consult your device documentation for instructions.In weather forecast apps or websites, we can see a live weather map - when drawn clouds move on the territory. On mobile devices, you can save the bookmark as an easy-access icon similar to other apps.
