What to expect during the 2022 Atlantic hurricane season

Posted on 22 June 2022 by Guest Author

This is a re-post from Yale Climate Connections by Samantha Harrington

It’s officially hurricane season in the Atlantic Ocean, and it’s expected to be an active one. In a webinar on Friday, June 3, Eye on the Storm meterologists Jeff Masters and Bob Henson presented a preview of the 2022 Atlantic hurricane season. Here’s what we learned:

  • The Atlantic is expected to have an active hurricane season this year. Colorado State University scientists predict 20 named storms and 10 hurricanes, including five major hurricanes. NOAA’s forecast calls for slightly fewer storms but still puts the odds of an above-average Atlantic hurricane season at 65%. The waters of the Gulf of Mexico are warm, which means storms there will have plenty of fuel. 
  • Peak Atlantic hurricane season occurs in September because wind shear is typically at its lowest at that time of year, while water temperatures are at their highest and the west African monsoon, which causes tropical waves to form off the coast of Africa, is most active. 
  • At-risk locations are difficult to predict this early in the season. The position of the Bermuda High influences tropical storm steering currents, and meteorologists can’t accurately forecast the position of the high more than two weeks in advance. But conditions in the Atlantic are similar to those in 2021, which may suggest a slightly higher risk for the Gulf Coast than other locations. 
  • Rapid intensification risks are increasing. Rapid intensification is defined as when the maximum sustained winds of a storm increase by at least 30 knots (35mph; 55km/h) in just 24 hours. Deep warm water in the Gulf of Mexico sets the stage for rapid intensification of tropical cyclones. The good news is that forecasts for rapid intensification are getting better. The rapid intensification of Hurricane Ida was predicted well in advance of landfall last year. 
  • The best forecast to watch is the official one from the National Hurricane Center. During the 2021 season, the National Hurricane Forecast outperformed all of the top models at all time periods. Models are improving their ability to predict rapid intensification, but may be at their upper limit for predicting storm tracks, which have gotten very accurate. 
  • Climate change is affecting hurricanes, but there’s still a lot to learn. A larger proportion of hurricanes are getting more intense, and even as storms move inland, they are staying stronger longer than they did in the past. And we can expect to start seeing more “homegrown hurricanes” developing off the East Coast – like 2021’s Tropical Storm Henri – rather than arising from disturbances off the coast of western Africa.

  1. As this is your first post, Skeptical Science respectfully reminds you to please follow our comments policy. Thank You!

    I would like someone in authority to consider using 4 drones armed with napalm or similar  to fire into the spout of a tornado from 4 different directions just below where it fans out and up into the sky to disapate the cold air with massive heat to stop the tornado .

    If this were to succeed , Tornadoes could be nutralized forever

  2. This does not tally with what I understand about tornado formation. In fact, it seems rather like the idea of nuking hurricanes. (see www.nationalgeographic.com/science/article/hurricanes-weather-history-nuclear-weapons for why this is a terrible idea). Never mind the logistics of vast swarms of napalm-armed helicopter patrolling supercells looking for tornado formation...

  3. scaddenp : I never wrote about helicopters or nukes  .

    The vortex of a tornado is what has to be eliminated and to do that massive heat should affect  the updraught rotation thus dissapating the storm cell using drones no different to that of operating them   in Afganistan by remote from Las Vegas
