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. Having all stations plotted on a map guides you as to where high- and low-pressure systems, fronts, and the like are located, which ultimately helps you decide where to draw them in.In weather forecast apps or websites, we can see a live weather map - when drawn clouds move on the territory. But if you'll be analyzing a weather map by hand, station plot data is often the only information you start off with. If a weather map has already been analyzed, you'll find little use for the station plot data. Sky cover (also as one of NOAA's symbols).Current weather (marked as one of dozens of symbols established by National Oceanic and Atmospheric Administration or NOAA).Dewpoint temperature (degrees Fahrenheit).Air temperature (in degrees Fahrenheit).They include reports of a variety of weather data at that location: Station plots describe the weather at a station location. (When reading the chart, note whether the time of year is daylight saving time or standard time and read accordingly.)Īs seen here, some surface weather maps include groupings of numbers and symbols known as weather station plots. If you're in California (which is Pacific Coastal Time) and the UTC issue time is "1345Z" (or 1:45 p.m.), then you know that the map was constructed at 5:45 a.m. If you're new to Z time, using a conversion chart (like the one shown above) will help you easily convert between it and your local time. Known as Zulu or Z time, this figure is included on a weather map so that all meteorological weather observations (taken at different locations and therefore, in different time zones) can be reported at the same standardized times no matter what the local time might be. It tells you when the weather map was created and also the time when the weather data in the map is valid. One of the first coded pieces of data you might notice on a weather map is a 4-digit number followed by the letters "Z" or "UTC." Usually found at the map's top or bottom corner, this string of numbers and letters is a timestamp.
