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...
