Atlantic Hurricane Season

What is El Nino?

El Nino is a periodic change in the currents of the Pacific Ocean that occurs every five to eight years and brings unusually warm water to the coast of northern South America.

How Does It Affect Atlantic Hurricanes?

During El Niño years, the Pacific basin experiences a reversal of easterly trade winds, which disrupts the normal flow of ocean currents. As a result, hurricane activity generally increases in the Pacific basin.

The Atlantic basin generally experiences an increase in upper-level wind speeds during El Niño years, resulting in decreased hurricane activity. These faster upper-level winds disrupt the relatively uniform wind speed and direction needed for hurricane formation, and thunderstorm complexes rip apart before they can develop into hurricanes.

what is the bermuda high?

The Bermuda High pressure system sits over the Atlantic during summer. Acting as a block that hurricanes cannot penetrate.

How does it affect atlantic hurricanes?

The Bermuda High dictates where the hurricane will go. Hurricanes cannot go through this high pressure system so, thy will skirt around the edge until they passes it. The location and size of this system determines where these hurricanes go. A normal Bermuda High often leads to hurricanes moving up the east coast and out to sea.

What Is Water Temperature?

Water temperature is how hot or cold the water is.

How does it affect Atlantic hurricanes?

The warmer the water, the more energy to fuel the hurricane making it stronger. The colder the water, the less energy to fuel the hurricane making it weaker.
