How Cyclones are tracked in India?

ISRO uses geo-stationary and low earth orbit satellites for providing experimental inputs on cyclogenesis, cyclone track, cyclone intensity. INSAT series of satellites with frequent imaging provide the cyclone parameters for near real time analysis.

How do satellites help in combating cyclones?

“Satellites play a critical role in forecasting, particularly during cyclones, helping us describe the initial parameters fed into the weather models, closer to the actual atmospheric conditions. This helps us better our forecast,” said IMD director general KJ Ramesh.

Who gave the name cyclone Fani?

At the same time, the JTWC began warning on the system, designating it 01B. Six hours later, the IMD upgraded the system to a cyclonic storm and gave it the name Fani.

Is a communication satellite of India?

The Indian National Satellite (INSAT) system is one of the largest domestic communication satellite systems in Asia-Pacific region with nine operational communication satellites placed in Geo-stationary orbit.

How are cyclones tracked?

Surface pressure, wind circulation centre, and the cloud system centre are parameters used to position the cyclone centre. In many cases, these positions are not coincident. Surface observations, satellites, and land-based radar are the most common method used to locate the centre and determine the intensity.

How do satellites detect cyclones?

The GOES satellites orbit at the same rate as the Earth spins, which allows them to stare at hurricanes as they evolve. That, combined with advances to the sensors, gives us a view of hurricanes in motion. You get to see the hurricane eye wall forming. You can see it actually forming in real time.

What are the advantages of using satellite images to track cyclones?

When a hurricane is well offshore and out of effective radar range, forecasters use satellite imagery to continuously track the storm’s movement and development. The imagery gives information about the top of the storm. Satellites can also give information about the winds speeds over the ocean surface.

What is the advantage of using satellite image and weather radar in monitoring tropical cyclones?

Meteorological satellite cloud imagery can fill the data gap of conventional observations and provide important clues for forecasting the status and development of tropical cyclones when they are included in day-to-day weather forecasting operations.

Who kept the name Nivar cyclone?

Cyclone Nivar is the fourth cyclone to hit the North Indian Ocean region in 2020. The name ‘Nivar’ has been selected from the list of names given by Iran. In the Parsi language, the name ‘Nivar’ means light.
