![]() This data can then be used in computer forecasting models to predict future weather trends, while alerting meteorologists to upcoming precipitation, storms or severe weather. Radar can decipher how far away precipitation is, its speed and how big droplets or snowflakes are. Meteorologists have many tools at their disposal, including radar, to predict the weather forecast. ![]() How does radar help meteorologists predict the weather? When measuring the change in phase between a transmitted pulse and the received echo, the target's movement toward or away from the radar can be calculated. When pulses of radio waves are transmitted, the system keeps track of the phase of those pulses. What is Doppler Radar and how does it work?ĭoppler radar systems provide information about the movement of targets as well as their position. Precipitation type, motion, turbulence and many more useful determinations can also be made, such as recognizing the debris that a tornado would throw into the air (known as a debris ball). Weather forecasters determine the distance to an oncoming storm and the amount of precipitation by the strength and speed of the pulse returning to the weather radar site. ![]() This enables a meteorologist to analyze and interpret the type of weather occurring dozens of miles away from the radar. If the radar beam bounces off precipitation such as rain or hail, the beam will return to the weather disk, where the data is processed into various parameters. This focused beam radiates outward from an antenna (also known as a radar dish). Weather radar utilizes either a solid-state or tube transmitter to send energy pulses (also known as radar beams) into the air to detect precipitation. As a result, radar can be an exceptional tool in a meteorologist’s arsenal for helping to protect life and property. Meteorologists can use this information to determine specific areas where dangerous weather conditions exist. When the electromagnetic pulse strikes an object such as a raindrop or a snowflake, the wave reflects back to the radar with data that can be analyzed by meteorologists. Weather radar (also known as Doppler weather radar) is an instrument that sends pulses of electromagnetic energy into the atmosphere to find precipitation, determine its motion and intensity, and identify the precipitation type such as rain, snow or hail. That’s why we compiled the most frequently asked questions to create a basic overview of radar technologies, options and benefits. “We cannot prevent disasters, but can mitigate them by following the IMD’s warnings and taking appropriate action in time,” he said.Weather radar is always a hot topic among our clients. He also said states should urge their agencies to utilise the IMD’s alerts. Rijiju said India’s weather forecasting systems and results in the past few years are better than almost all other systems in existence worldwide. ![]() Radars are preferred over satellites because they have a higher resolution and can provide observations every 10 minutes, officials say. ISRO will also launch some more satellites for observation,” he said. This is the optimal number of radars which will ensure there are no gap areas. “A total of 68 radars can cover the entire country. “We will increase the number of doppler radars from 35 presently to 68 in the next three years,” he revealed.Ī senior ministry official said the IMD is bolstering its observational network by augmenting radars, automatic weather stations, rain gauges and satellites to enhance predictability. He urged the private sector to step forward and manufacture weather-forecasting-related equipment.Įmphasising the crucial role of the IMD in light of climate change, Rijiju underscored the need to strengthen the department’s observational capacity. “Twenty-two doppler radars have been successfully commissioned during this period throughout the country, all manufactured in India, showcasing our self-reliance,” Rijiju said. He emphasised the significant enhancement in India Meteorological Department’s (IMD) capacity since 2014 with the installation of new equipment. New Delhi: Earth Sciences Minister Kiren Rijiju announced on Wednesday the India Meteorological Department will expand its doppler radar network with the addition of 33 radars over the next three years, ensuring comprehensive observational coverage across the country.ĭuring a press conference, Rijiju said India’s weather forecasting systems have outperformed their global counterparts and delivered accurate results in recent years.
