How advances in science and computer modeling have lead to improvements in studying hurricanes.

Before making landfall, Katrina was classified as a Category 5 storm. This simulation shows the storm’s wind speeds from Aug. 22-30, 2005.

Water vapor in the atmosphere helps to fuel storms. This simulation shows water vapor within Katrina from Aug. 22-30, 2005.

Model resolution has greatly improved over the last 10 years. These images show Katrina’s winds using a model from 2005 (left) and 2015 (right).

Today's models have up to 10 times higher resolution. These images show water vapor within Katrina at 50 km resolution (left) and 6.25 km (right).
