How is cyclone monitored by satellite technique ?
The satellite technique can be used to find out the centre and intensity of the system. It can also be used to find out various derived parameters which are useful for monitoring and prediction of the cyclones and associated disastrous weather. Dvoraks technique based on pattern recognition in the cloud imagery based on satellite observation is used to determine the intensity of cyclonic storm. For this purpose a T. No. where T stands for tropical cyclone is assigned to the system. This scale of T Nos. varies from T 1.0 to T 8.0 at the interval of 0.5. The T 2.5 corresponds to the intensity of a cyclonic storm. The detailed classification of cyclonic disturbances based on above technique is given below: T CLASSIFICATION OF CYCLONIC STORM AND CORRESPONDING WIND SPEED AND PRESSURE DEFECT (?
