Why the Cyclone will move in Northeastwards Direction?
The above picture shows the model output of winds at the height of 12 kms. These winds mostly governs the path of Cyclone and they are known as “Steering winds”.
The winds in the red box shows the strong Steering winds blowing upto 80 kmph to 100 kmph in southwesterly direction. Hence the cyclone once it reaches the “Ridge line” will then recurve to follow the steering winds and move in Northeastwards direction.
(Ridge line is imaginary line along which the winds curve in clockwise direction).
