About
Dvorak technique
- The Dvorak technique is a statistical method for estimating the intensity of tropical cyclones (TCs) from the interpretation of satellite images.
- Forecasters uses satellite images to recognise the pattern from the observed structure of the storm, and locate its eye.
- It was first developed in 1969 and tested for observing storms in the northwest Pacific Ocean.
- This technique gives the best estimates of the cyclone intensity — a vital component while issuing weather warnings.
