![]() ![]() In weather forecast apps or websites, we can see a live weather map - when drawn clouds move on the territory. But how is it possible?ĭata for these animated maps is obtained from weather radars located all around the world. ![]() These radars help to predict rain and snow, and other precipitation, but also wind and extreme weather such as thunderstorms or tornadoes. Let's take a closer look at what is weather radar, what they are for, how such radars work, and more. The definition of weather radars and their purposeĪ weather radar is modern meteorological equipment. 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. Weather radars can help measure wind speed, too. Wind radars help to detect tornadoes and accurately calculate when bad weather gets to a particular city or region. It also allows you to observe the devastating path of storms. The name "radar" appeared in the early 1940s. It is formed from the abbreviation RADAR - Radio Detection And Ranging. The first weather radars appeared in the 1950s in the United States and Canada. Typical radar is a four-story building size. There is a huge ball at the top of the radar - this is a shelter for the antenna that is inside. The interactive map makes it easy to navigate. Its radius of action in the atmosphere is on average 200-250 kilometers. See the latest United States RealVue weather satellite map, showing a realistic view of United States from space, as taken from weather satellites. There is usually a small building near the radar, where employees monitor the health and operation of the radar. 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.Radar processor - analyzes the radar data.So the interactive radar is crucial to making accurate real-time “now cast” weather forecasts of precipitation. 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. Some examples: US National Oceanic and Atmospheric Administration ( NOAA), Met Office UK, Meteorological Service of Canada. ![]() There are also private services.īased on this data, rescue and meteorological services in different countries inform the population about the necessary precautions. 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. While the top end Tier 2 package adds in hail and shear contouring (the latter necessary for tornado formation), as well as multi-platform use and a 30-day radar archive.īut even for just $9.99 for the app alone without the tiered options, the standard data is fantastic.Photo: radar under construction in Puerto Rico / FEMA / Eduardo Martinez / Vertical magazine The main types of weather radars This is due to the fact that different services may use different meteorological models and calculation systems. Stepping up to the Pro Tier 1 subscription for $9.99 per year gets you longer animations and lightning data (a must for outdoor enthusiasts), dual pane capability, and inspection tools. You have access to every single radar product that the pros do, at practically the same time they see them-along with up to the minute warning information. Available on Android and iOS for $9.99 and Windows or Mac for $29.99, this app is one of the quickest updating around. If none of the above weather apps have what you’re looking for, and you’re willing to spend money on a quality professional weather radar app or website that storm chasers use, hands down our top recommendation is RadarScope. However, the smoothing is addressed in a premium radar option, which offers higher resolution imagery and the previously mentioned forecast radar imagery. In turn, this may cause some inaccuracy in the data, especially when zoomed in. If we had to pick a negative with this one, it’s that the app smooths radar imagery too much to make it look nice on the screen. It also has an innovative future radar option, which attempts to forecast future storm movement up to six hours in advance using the company’s proprietary short-range modeling. ![]() Zooming in and out of imagery is fluid, and the satellite map used allows you to zoom down to street level. According to Forecast Advisor, The Weather Channel is consistently rated as the most accurate weather app for many cities across the country.Īlthough it’s a more general weather app, there are some great radar features that we think are worth mentioning. The Weather Channel’s app continues to be one of our top radar apps for 2023, and in our opinion, it’s the best actual mobile weather app. ![]()
