    A 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 tornado...

    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. All modern radars are mostly Dopplers. Why such a name? These radars are based on a Doppler effect, named after the Austrian physicist Christian Doppler, who described it in 1842. It consists in the ...

    Doppler and all other weather radars work on the principle of reflection, or echo: 1. The radar antenna emits directional radio signals with a wavelength of 1 to 10 cm into the atmosphere in the form of short-term high-power pulses. 2. In the atmosphere, impulses that meet objects — raindrops, turbulent currents, or surfaces — are reflected from th...

    Among all the benefits that radars bring, they have a number of significant limitations that make it impossible to get weather data the way we would like it to be: 1. The data from weather national radars can be not very accurate due to interference. It can happen because the objects that reflect the radio beams are very small. 2. The requirements ...

    There are not many weather radars in the world. In total, according to the World Meteorological Organization (WMO), there are about 1500 operating radars. Not a lot, right? By comparison, there are officially about 40.000 meteorological stationsin the world, which are the main tools for collecting weather information. (But data from radars can be o...

    A live weather radar map is processed radar data in real-time (in fact with a slight delay), displayed electronically on the map. Areas of precipitation, marked with different colors, move on this map. Typically, the intensity and nature of precipitation are shown in different colors. And it may be displayed differently in different applications. I...

    See the figure below for a map of all radar locations in the U.S. and other territories. When you see a radar image on TV, it is likely a combination of individual Doppler radars or a section of the NEXRAD network that you are looking at. Why is this? An individual radar sits inside a dome that rests on a tower about 100 feet tall. As the

    Jun 5, 2015 · Summary. Radar: an active remote sensor. To gather information about the world around us, we rely on a variety of sensing mechanisms. Some, such as touch or taste, are based on in situ sensing: the sensor must be in direct contact with an object to gather information about it.

    Summary. If you live in an affluent country, chances are good that one or more radars dedicated to the monitoring of weather take regular measurements of the atmosphere above you. Radar has become a standard instrument in meteorology, joining the thermometer, the radiosonde, and satellite-based imagers as tools used operationally in weather ...
