Anvil Growth (contd)
Quantitative measure of anvilgrowth (contd)
**Caution here!**
Anvil growth rates are also dependent on image frequency!
The figures below show anvil growth rate calculated between consecutive images with one minute and seven minute image intervals. The algorithm here finds the first temperature contour enclosing > six pixels in area and then monitors its change in the next image.

The two images above are for the same storm during 31 May 1996.
The best way to use the anvil growth technique is to be consistent in how you use your image interval frequency
