मुसळधार पाऊस पडणार आहे, की वादळ येणार, याची माहिती डॉप्लर हवामान रडार पुरवते. नागपुरात मोठा फुटबॉल असल्याचं नागरिकांना वाटते, मात्र तो डॉप्लर हवामान रडार आहे.
00:00main purpose of radar is to deliver the nowcast for the general public the nowcast
00:06is called the next three to six hours what is the chance of weather in the in the working of
00:14the range of radar range of radar is almost 500 kilometer from nagpur so within the range of that
00:20500 kilometer diametrically thousand kilometer what is about to happen in next three to six
00:25hours that is the main purpose of radar that is what the target and working principle material
00:33this radar is working in s-band frequency s-band means uh it's a peculiar frequency 2.8 gigahertz
00:39frequency so in this frequency our radar will transmit electromagnetic waves from the site
00:47and these waves um in 360 degree it rotate and it will cover the echoes from different in within the
00:54360 degree and it is transmit um reaching back to the radar and from the reach um signals returned
01:01back using our hardware and our software in connection they will it will analyze the
01:08reflected pictures and it will generate radar products from this radar products we the scientist
01:17and some scientific persons deployed in the floor will go through the images and they will detect or
01:24they will analyze identify what is the weather or what will be the coming weather like that
01:30decision will be taken from the image products
01:38a med star ka radar a working principle model a med star 1998 dw like that
01:46is
02:00It was a 40-41 radar.
02:01When we install it, this is the third radar in India.
02:06It was the third radar.
02:09But now, there are two different radar in India.
02:13This is an advanced radar.
02:17Sir, the radar is connected to the satellite.
02:22How much is the use of the vehicle for the vehicle?
02:27How much is the use of the vehicle?
02:29Actually, by working on this radar, we are getting the current weather situation in an
02:35area of 1,000 km in the range.
02:39So, within that area, we are getting the current weather scenario.
02:45And from that, we can inform the general public what is the current scenario and what is about
02:51to happen in the next three hours.
02:54So, with satellite images, we can extend this thing.
02:58But satellite is in a elevated position.
03:02So, it is not good to compare with satellite images.
03:08So, what is the size of the antenna?
03:12Size of the antenna is almost 9.5 meter diameter.
03:16And if you are going through the working principle of this antenna, what you see there, it is in a current, at a single position.
03:26During working, this radar will rotate up to 60 degree.
03:31And once completing one 360 degree, it will change its elevation angle.
03:35So, suppose if now it is in zero, then the next elevation angle it will go to 0.5.
03:41Then again it will rotate 360 degree.
03:43Then again it will change its elevation position at next level.
03:47Like that it will move up to 21.5 degree.
03:50And each this elevation angle, it will complete one full circle.
03:54I mean, technically it is called asimuth.
03:57Asimuth and elevation.
03:59How is the extra velocity in radar?
04:03Today it is working in 2.8 gigahertz.
04:06How exactly this working principle is from, like I told earlier, it is transmitting the electromagnetic signals from here.
04:13And these electromagnetic signals get reflected from meteorological target.
04:18Meteorological target means clouds, water drops like that.
04:23From meteorological target, reflected signals we are getting back.
04:26And from that signal, we are analyzing the backscatter reflected profiles.
04:31And from that, we are generating the images.
04:34From that images, these, what to say, these nowcast messages are analyzed.
04:41And we are generating, human beings are generating the nowcast messages.
04:46And this radar got the best radar award in 2023 within India, within IMD.
04:53Also, Doppler Weather Aids and primarily it is one of the two-star chapters that we are generating.
04:54So Doppler Weather Adar is a lot of instrument for the summer, which we will be able to do in the next 3-6 hours.
05:05We will be able to do in the next 3-6 hours, which we will be able to do in the next 3-6 hours.
05:16Doppler Weather Adar will be able to do in the next 3-6 hours, which we will be able to do in the next 3-5 hours, which we will be able to do in the next 3-6 hours.
05:36We will be able to do in the next 3-6 hours, which we will be able to do in the next 3-6 hours, which we will be able to do in the next 3-6 hours.
06:01We will be able to do in the next 3-6 hours, which we will be able to do in the next 3-6 hours, which we will be able to do in the next 3-6 hours.
06:19We will be able to do in the next 3-6 hours, which we will be able to do in the next 3-6 hours, which we will be able to do in the next 3-6 hours.
06:26We will be able to do in the next 3-6 hours, which we will be able to do in the next 3-6 hours, which we will be able to do in the next 3-6 hours.
06:33We will be able to do in the next 3-6 hours, which we will be able to do in the next 3-6 hours, which we will be able to do in the next 3-6 hours.
06:40We will be able to do in the next 3-6 hours, which we will be able to do in the next 3-6 hours, which we will be able to do in the next 3-6 hours.
