The first lesson is one that I always mention. It only takes “one” storm. The season ended up “average to above average” in terms of activity. According to NOAA, an average season will produce 12 named storms, six becoming hurricanes and three within the category 3 to 5 range on the Saffir-Simpson scale. If you look back at early summer seasonal projections, most organizations in the seasonal prediction business predicted below average activity because of cool sea surface temperatures in the Atlantic basin early on and the specter of El Nino onset. These projections are useful for certain industries to plan, but they should never cause people to let their guard down.

The second lesson was that the American public became more familiar with the term “subtropical” storm. A NOAA press release notes,

A record seven named storms (Alberto, Beryl, Debby, Ernesto, Joyce, Leslie and Oscar) were classified as subtropical at some point. The previous record of five subtropical storms occurred in1969 A subtropical storm is a named storm that has tropical and non-tropical characteristics. All subtropical storms this season eventually transitioned into a tropical storm, with three (Beryl, Leslie and Oscar) eventually becoming hurricanes.

Interestingly, the term caused confusion for many non-meteorologists. My colleague Tom Moore, a veteran meteorologist wrote in social media earlier during the season,

To clear things up FYI… A subtropical storm is not weaker than a tropical storm …for most purposes … the term is meaningless to all but meteorologists .. You can have a subtropical storm or a tropical storm with max sustained winds of 70 mph.”

I appreciate scientific designations and the need for record keeping. However, I am always an advocate of reviewing “the inertia of practice” from time to time. It is perfectly fine, in my view, to ask questions about how we do things and question whether we do them because “we just always did.” We saw such a review in the wake of Hurricane Sandy because of confusion associated with what it was called and who had responsibility for communicating about it.

The third lesson is not a new one, but one that the media and community grabbed onto in the wake of Hurricane Florence. Florence, like Harvey in 2017, was a “wet” storm. It was not about the wind. Florence broke all types of flood records in the Carolinas and led to numerous fatalities. Like Harvey, many people didn’t seem to understand the magnitude of the rainfall threat. This led to calls for abandonment or augmentation of the Saffir-Simpson wind scale because it conveys nothing about the rainfall threat. I heard many stories of people that evacuated flood prone regions when the storm was Category 3+ returning once they heard that the storm was a lower category. The problem is that the flood threat for many of those people never changed. This is not a new challenge, but Florence certainly sparked discussion once again. Many meteorological and communication experts continue to work on this problem. I will argue that if something is ultimately done, it should be thoughtful and of value to the stakeholder community rather than a knee-jerk, academic response.

The fourth lesson is also not a new one but should be mentioned here for completeness. Intensity forecast accuracy continues to lag track forecasts. This has been known for decades within the meteorological community. Hurricane Michael, like many storms in the past few years, exhibited rapid intensification. According to a NOAA press release, Hurricane Michael “was the third-most-intense hurricane to make landfall in the continental U.S. on record in terms of central pressure (919 mb) and the fourth-strongest in terms of maximum sustained winds (155 mph).” Models and forecasters started hinting 2 to 3 days in advance that Michael would likely be a major hurricane, but most projections did not see a category 4/5 level storm. I have previously described why the intensity forecasts are more challenging. Likewise, models pretty much nailed the track and “slow down” of Florence but initially projected a stronger storm at landfall.

A fifth lesson revealed to me after Michael is that people have thresholds for action. From my perspective, I would likely make the same decision for a Category 3, 4, or 5 storm. However, it is known that many coastal residents have their own mental models and decision-making process. Some will stay for a Category 3 storm but leave for a Category 4 storm even though there may be very little difference in damage outcomes for a high-end Category 3 or low-end Category 4 storm. Social scientists are exploring the motivation behind such logic. I hope we can make progress soon because unfortunately many people only adjust their personal decision-trees after experiencing the storm’s destruction.

The final lesson relates to climate change. I am not going to re-invent the wheel with this discussion because the NOAA Geophysical Fluid Dynamics Laboratory website is an excellent and updated source of where the science stands on linkages between climate change and hurricanes. It is probably naive to completely dismiss the role of higher sea level in the storm surge of storms like Michael. It is physically reasonable that warmer ocean waters would affect intensification processes and the range where storms form. Did you noticed hurricanes headed to Europe two years in a row? It is scientifically-plausible that large scale process related to changing jet stream patterns or El Nino would impact hurricanes. Scientists will continue to clarify these issues, but the tiring back-and-forth rhetoric during storms must cease. Lives in the short-term and long-term may be at stake.

The calendar states November(*********************************************************************** )th, which implies the” end “of the Atlantic typhoon season. The2018 season will definitely be kept in mind for Cyclone Florence and Cyclone Michael, however the season provided us 15 called storms. Of those, 8 were cyclones, and 2 of those reached “significant” status (classification 3 to 5). As I review the season with my meteorologist, researcher, science communicator, and discipline management “hats on,” respectively, I see 6 crucial lessons.

The very first lesson is one that I constantly discuss. It just takes “one” storm. The season wound up “typical to above average” in regards to activity. According to NOAA, a typical season will produce 12 called storms, 6 ending up being cyclones and 3 within the classification 3 to 5 variety on the Saffir-Simpson scale. If you recall at early summer season seasonal forecasts, many companies in the seasonal forecast organisation forecasted below par activity since of cool sea surface area temperature levels in the Atlantic basin early on and the specter of El Nino beginning. These forecasts work for specific markets to strategy, however they must never ever trigger individuals to let their guard down.

The 2nd lesson was that the American public ended up being more knowledgeable about the term “subtropical” storm. A NOAA news release notes,

A record 7 called storms (Alberto, Beryl, Debby, Ernesto, Joyce, Leslie and Oscar) were categorized as subtropical eventually. The previous record of 5 subtropical storms took place in1969 A subtropical storm is a called storm that has tropical and non-tropical qualities. All subtropical storms this season ultimately transitioned into a hurricane, with 3 (Beryl, Leslie and Oscar) ultimately ending up being cyclones.

Surprisingly, the term triggered confusion for lots of non-meteorologists. My associate Tom Moore, a veteran meteorologist composed in social networks previously throughout the season,

To clear things up FYI … A subtropical storm is not weaker than a hurricane … for many functions … the term is worthless to all however meteorologists. You can have a subtropical storm or a hurricane with max sustained winds of 70 miles per hour.”

I value clinical classifications and the requirement for record keeping. Nevertheless, I am constantly a supporter of evaluating “the inertia of practice” from time to time. It is completely great, in my view, to ask concerns about how we do things and concern whether we do them since “we simply constantly did.” We saw such an evaluation in the wake of Cyclone Sandy since of confusion related to what it was called and who had obligation for interacting about it.

The 3rd lesson is not a brand-new one, however one that the media and neighborhood got onto in the wake of Cyclone Florence. Florence, like Harvey in 2017, was a “damp” storm. It was not about the wind. Florence broke all kinds of flood records in the Carolinas and caused various casualties. Like Harvey, many individuals didn’t appear to comprehend the magnitude of the rains risk. This caused require desertion or enhancement of the Saffir-Simpson wind scale since it communicates absolutely nothing about the rains risk. I heard lots of stories of individuals that left flood vulnerable areas when the storm was Classification 3+ returning as soon as they heard that the storm was a lower classification. The issue is that the flood risk for a lot of those individuals never ever altered. This is not a brand-new difficulty, however Florence definitely triggered conversation as soon as again. Numerous meteorological and interaction specialists continue to deal with this issue. I will argue that if something is eventually done, it must be thoughtful and of worth to the stakeholder neighborhood instead of a knee-jerk, scholastic action.

The 4th lesson is likewise not a brand-new one however must be pointed out here for efficiency. Strength projection precision continues to lag track projections. This has actually been understood for years within the meteorological neighborhood. Cyclone Michael, like lots of storms in the previous couple of years, showed quick surge. According to a NOAA news release, Cyclone Michael “was the third-most-intense typhoon to make landfall in the continental U.S. on record in regards to main pressure (919 mb) and the fourth-strongest in regards to optimum sustained winds (155 miles per hour).” Designs and forecasters began hinting 2 to 3 days ahead of time that Michael would likely be a significant typhoon, however many forecasts did not see a classification 4/5 level storm. I have actually formerly explained why the strength projections are more difficult. Also, designs practically nailed the track and “decrease” of Florence however at first forecasted a more powerful storm at landfall.

A 5th lesson exposed to me after Michael is that individuals have limits for action. From my viewpoint, I would likely make the exact same choice for a Classification 3, 4, or 5 storm. Nevertheless, it is understood that lots of seaside citizens have their own psychological designs and decision-making procedure. Some will remain for a Classification 3 storm however leave for a Classification 4 storm although there might be really little distinction in damage results for a high-end Classification 3 or low-end Classification 4 storm. Social researchers are checking out the inspiration behind such reasoning. I hope we can make development quickly since regrettably many individuals just change their individual decision-trees after experiencing the storm’s damage.

The last lesson associates with environment modification. I am not going to re-invent the wheel with this conversation since the NOAA Geophysical Fluid Characteristics Lab site is an exceptional and upgraded source of where the science bases on linkages in between environment modification and cyclones. It is most likely ignorant to entirely dismiss the function of greater water level in the storm rise of storms like Michael. It is physically sensible that warmer ocean waters would impact surge procedures and the variety where storms form. Did you discovered cyclones headed to Europe 2 years in a row? It is scientifically-plausible that big scale procedure associated to altering jet stream patterns or El Nino would affect cyclones. Researchers will continue to clarify these problems, however the tiring back-and-forth rhetoric throughout storms need to stop. Lives in the short-term and long-lasting might be at stake.
