![]() ![]() Now it is the case that the accuracy of the measurement decreases with increasing distance. Only then can a concrete picture of precipitation in the area emerge. To display these results in a radar image, one needs not only one, but several stations at different locations. How is a weather radar created?Īs you already know, the radar station and its radar beams are used to measure the amount of water vapor present in a cloud. Only the use of new types of radar technologies, such as the Doppler radar, made this possible. …that the first weather radar was already built in the early 1940s? However, this type of weather radar could not accurately predict the intensity of the rain or the strength of the thunderstorm or storm. This central computer is responsible for processing all the collected data and using it to create a picture of the general weather situation. These weather stations are linked to each other and transmit the collected data to a central computer. To be able to make a concrete weather forecast and to collect and analyze the data over a large area, many different weather radar stations are required at various locations. What is a weather radar live?Ī weather radar live is a special type of radar that collects and analyzes data on the weather situation. You can also zoom in with your fingers or the mouse wheel. Use the + or – at the top right to zoom in. ![]() ![]() By finger pressure or mouse click you can move the area on the map. With the cursor at the bottom left in the center you can view the weather over time. The weather radar live itself displays cloud cover, current precipitation, storms, thunderstorms or tornados in real-time. This is how the weather radar live works: Increasing incidents of flash floods and cloudbursts in the hill states of Himachal Pradesh, Uttarakhand and Jammu and Kashmir and other parts of the country due to climate change has led to increasing need for accurate forecasting for such events.Īccurate predictions are needed to save lives and forecast of weather, including monsoon and cyclones given the fact that India’s GDP is largely dependent on agriculture, short and long term planning and strategy development.Depending on the intensity, the precipitation appears on the rain radar in the colors blue (weak precipitation), green, yellow, orange (moderate precipitation), red or purple (very heavy precipitation). Thunderstorms and lightning strikes are indicated by a small lightning symbol. Division of Doppler Radars and their applications: Doppler radar can be divided into several different categories according to the wavelength which are L, S, C, X, K.It provides advanced information, enhancing the lead-time so essential for saving lives and property, in the event of natural disaster associated with severe weather.It has the equipment to measure rainfall intensity, wind shear and velocity and locate a storm centre and the direction of a tornado or gust front.It is designed to improve precision in long-range weather forecasting and surveillance using a parabolic dish antenna and a foam sandwich spherical radome.It is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance.It has its own source of illumination (a transmitter) for locating targets.It is a device that uses electromagnetic waves in the microwaves region to detect location (range & direction), altitude, intensity and movement of moving and non-moving objects.Doppler Effect works on both light and sound objects.It was discovered by Christian Johann Doppler who described it as the process of increase or decrease of starlight that depends on the relative movement of the star.Doppler Effect refers to the change in wave frequency during the relative motion between a wave source and its observer.While two more radars mean that 70 per cent of Himachal will be covered, there is need for more, including one at Lahaul-Spiti–which is also of strategic importance due to proximity to the China Border touching J&K and Ladakh. The IMD has taken proactive steps to increase the number of radars from 15 in 2013 to 37 in 2023 and will add 25 more in next 2-3 years, he said in presence of Chief Ministers of Himachal Pradesh and Uttarakhand and LG of J&K-the three Himalayan States most prone to the extreme events in the country. They include two at Murari Devi and Jot in Himachal Pradesh, and one each at Banihal Top in Jammu and Kashmir and Surkandaji in Uttarakhand covering a radius of 100 km.īuy Prime Test Series for all Banking, SSC, Insurance & other exams More About This Deployment: ![]() Four new radars were added recently taking the number from 33 to 37. The entire country will be covered by Doppler Weather Radar Network by 2025 to help predict extreme weather events more accurately, union minister Jitendra Singh said, speaking at the foundation day of India Meteorological Department. ![]()
