Sandy WAS more powerful than Hurricane Katrina – and it is the second most powerful storm in modern history
- Sandy was more powerful than the Hiroshima atomic bomb
- The storm surpassed Hurricane Katrina, given the power associated with the size ratio
- Sandy can become the second most expensive hurricane behind Katrina
- Although it was only Category 1 during the landing, Sandy generated a significant storm surge over hundreds of kilometers
Hurricane Sandy is the second most powerful hurricane in modern history, with an even higher than that of Katrina, according to a measurement of the strength of the hurricane in relation to its size.
Researchers have found that Sandy & # 39; s Integrated Kinetic Energy Index, or IKE, quantifies the strength of a hurricane based on how far the wind force of tropical storms extends from the center, second after hurricane Isabel in 2003.
Hurricane Sandy & IKE was 140 Terajoules, which was about 20 Terajoules higher than Katrina, according to Brian McNoldy, a senior researcher at the Rosenstiel School of Marin and Atmospheric Science at the University of Miami.

& # 39; Sandy & # 39; s IKE was more than 140 Terajoules (TJ, 1 TJ = 1 trillion Joules = 277,778 kilowatt-hours), meaning it generated more than twice the energy of the Hiroshima atomic bomb & # 39 ;, wrote McNoldy on a blog published by the Washington Post.
& # 39; At one point, many hurricanes contain more energy than just an atomic bomb in their surface winds (even excluding wind at higher altitudes and latent heat energy), & # 39; he added.
The category levels that are cited more generally to quantify the power of hurricanes are purely measures of wind speed. Katrina was measured as a category 3 hurricane on landing and later rose to a category 5.
The estimated cost of Hurricane Sandy is $ 20 billion

Sandy has since been measured as a category 1 hurricane on landing.
But Sandy can become the second most expensive hurricane in history after Katrina because of his high IKE, McNoldy noted.
& # 39; Sandy had category 1 wind on landing and yet been able to create a very significant storm flood over hundreds of miles of the densely populated coastline, & # 39; he wrote.

& # 39; Katrina & # 39; s IKE was more focused, Sandy & # 39; s IKE was more scattered. This unit of measurement – more than wind speed – displays the horrific effects of the respective storms.
Sandy has cost an estimated $ 20 billion in damage, while Katrina has cost around $ 106 billion.
