Estimation of Centre and Intensity of Tropical Cyclones over the North Indian Ocean Using Microwave Imageries - Monitoring and Prediction of Tropical Cyclones in the Indian Ocean and Climate Change - page 195

Fig. 4: Difference (km) in location of centre of CDs as estimated by Satellite
Meteorology Division of IMD based on geostationary satellite and Navy NRL based
on polar orbiting satellites.
the average difference in location estimated by IMD and NRL is about 97 km,
44 km and 33 km respectively.
Average difference in locations of centres estimated by Satellite Division
of IMD and SSD NOAA based on various microwave imageries is shown in
Fig. 5. Difference ranges from 17 km to 91 km. The highest difference 91 km
occurred in the case of F-13 satellite. Average difference is found to be 52 km.
