Hurricane Katrina
Katrina was initially labeled as the most destructive hurricane when it hit the Mississippi Gulf Coast and Louisiana in 2005, but normalizing it to other major hurricanes based on current conditions revealed that the Great Miami Hurricane of 1926, in fact, would have produced a damage level nearly double that of Katrina if it hit today.

Bermuda High
a semipermanent area of high pressure located over Bermuda in summer and fall that steers many storm systems westward across the Atlantic.
In summer, it can steer tropical heat into the eastern and southern US. During the Atlantic Hurricane Season, it determines whether a tropical storm visits a Florida political convention or goes for the gumbo near New Orleans. It shapes American weather and, unfortunately, it can be very unpredictable.
Look at the blank area in the satellite picture of the stormy Atlantic. That’s the Bermuda High. It is an area of high atmospheric pressure that drifts through the Atlantic. It is one of several high-pressure areas around 30˚N.
- The air from storms near the equator rises very high and eventually falls back down to earth around 30°North and 30°South.
- This sinking air pushes against the surface creating a high-pressure zone in the atmosphere
El nino
El Niño is characterized by unusually warm ocean temperatures in the Equatorial Pacific, as opposed to La Niña, which characterized by unusually cold ocean temperatures in the Equatorial Pacific. El Niño is an oscillation of the ocean-atmosphere system in the tropical Pacific having important consequences for weather around the globe.
