Hurricanes - Looking back and looking ahead By Ken McKinley
The World Meteorological Organization (WMO) recently announced the entrants to the "Hall of Fame" for the 2023 season. It's not really called the Hall of Fame, but rather it is the WMO Hurricane Committee deciding which names will be retired from the previous season and not used again moving forward. The retirements of names occurs when a system is unusually impactful. Typically this means that the system was quite strong, and that it also impacted a large population. Occasionally, though, a system's name can be retired even if it was not an unusually strong system, but its impacts were still very significant.
There are lists of names for each region of the globe where tropical cyclones regularly occur. For the Atlantic and the eastern Pacific there are six lists of names used, each list is assigned to a particular year. The lists are then reused every seventh year. This means that the lists of names which were used in 2023 will be used again in 2029.
Weather: Keeping Score on Hurricane Names By Ken McKinley
In the last newsletter I speculated on the possible retirement of hurricane names over the past two Atlantic hurricane seasons. Recall that it is the World Meteorological Organization (WMO) that generates the lists of names that are used for tropical cyclones around the world, and because of the Covid-19 pandemic, they had been unable to meet after the 2019 hurricane season to decide which names should be retired from the list because the storms were particularly impactful in terms of property damage and/or loss of life. The WMO committee in charge of this task finally met (virtually) in March of 2021 and made their decisions.

Tropical cyclones in the Atlantic and the Pacific By Ken McKinley
We are now well into the 2021 hurricane season and are watching the evolution of tropical cyclones in the Atlantic and the Pacific. In the past I have used these newsletters to present some information about particularly memorable hurricanes, but this time let's take a look at a system that, while impactful for some, has not been a historic system by any measure. This system was very slow to develop despite traveling over some rather warm ocean waters at times during the first part of its history. I will examine this system through a series of satellite images with comments on each.
