In general, there are five steps in the derivation of Cloud Motion Vectors :

Registration of Triplet
Cloud Tracers selection
Tracking of Cloud Tracer in the Target image
CMV Computation
Height Assignment
Quality Control of Cloud Motion Vectors.

INSAT-based CMVs are particularly useful in the analysis of upper winds during the monsoon season to study the formation of eddies, cross –equatorial flow, approach of the two separate branches of the monsoon.
Three levels of the INSAT CMV are:
Low Level CMV – 1000 hpa – 700 hpa.Medium Level CMV – 700 hpa – 300 hpaHigh Level CMV – 300 hpa and above.   _{Your Comment}
