Have you ever wondered about the significance behind the names given to fierce tropical storms and hurricanes? When a weather system powerful enough to be classified as a storm is detected, the World Meteorological Organization (WMO) assigns it a name. But how are these names chosen, and what do they mean? Let's delve into the fascinating world of storm names, their origins, and the meanings behind them.
Storm names, particularly for hurricanes, serve two critical purposes. Primarily, they help in quick identification and tracking of these powerful storms, especially in cases where multiple systems are active simultaneously. Additionally, using named storms in weather broadcasts makes it easier for the public to follow and understand news reports. But where do these names come from, and what do they signify?
The Naming Process and Lists
Since 1953, the WMO has maintained six lists of names for each Atlantic hurricane season. These names are rotated annually, with a new list starting each June 1st. Storms that exceed a sustained windspeed of 39 mph (hurricane strength) are assigned a name from the next available list.
Storms causing significant damage may have their names retired by the WMO, with a replacement chosen by the affected country's committee. For instance, Hurricane Katrina (2005) had its name retired due to the widespread devastation it caused in the United States. This shows that storm names can sometimes carry haunting memories and profound meanings for those affected.
Alphabetical and Regional Naming
Historically, storms were named after women, often saint's names like storms in the Mediterranean. However, since 2000, Atlantic storms have been named in alphabetical order using both male and female names. This approach aims to avoid any bias or discrimination. In other basins like the Pacific, storm names can have geographical, cultural, or traditional meanings, reflecting the heritage of the affected regions.
In the Northeastern Pacific, for example, storm names often come from consultations with communities and various sectors in the region, such as Mexico, Guatemala, El Salvador, and others. This collaborative process adds a layer of cultural significance to hurricane names in these areas.
International Influence and Changes
Some storm names have been contentious or required alteration due to their international significance or personal connotations. For instance, the name “Harvey,” which gained infamy during the devastating 2017 hurricane season in the United States, was later used, and renamed as “Hilary,” by the WMO for the 2018 Atlantic hurricane season to avoid misunderstandings or confusion with the infamous storm.
Additionally, storm names can be influenced by international cooperation and climate change agreements. During the United Nations' inaugural Ocean Decade, running from 2021 to 2030, a Special Ocean Decade in the WMO's naming lists, such as “Dhardhana” (meaning “ Flowing with Ocean”), reflects the globally collaborative approach to ocean conservation and sustainable management.
Storm Names and their Meanings
Storm names, especially those originating from Pacific regions, can hold rich, cultural, and symbolic meanings. For example, names like “Vir slices” (Vietnamese for “Seacoast”) or “Jolina” (a Filipino or Spanish name also meaning "strong-willed" or "humble one" respectively) reflect the geographical and cultural heritage of affected communities.
In Australia, storm names can be quite descriptive and telling of the storm's potential impacts. For instance, "Elsa," a 2020 storm that caused significant rainfall, reflects the name of the day (Easter Monday), reinforcing the storm's timing and the potential disruption it could cause, as Easter is a major public holiday in Australia.
Names Reflecting Strength and Power
Some storm names reflect their powerful nature and potential devastation. "Fjorgyn," a Norse goddesses of the sea, or "Carlojose" (an amalgamation of "Carlo" and "Joséphine," powerful characters in history) exemplify this trend. Names like "Megastorm" or "Blockbuster" emphasize the extraordinary intensity and impact of these storms.
Conversely, names can also denote positive or protective qualities, like "Protection" or "Defender," reflecting people's hopes and prayers for safety and resilience during storms. Some names, like "Oblivion" or "Doom," convey impending fear or destruction, emphasizing the need for preparedness and precaution.
Names Inspired by Nature and Infrastructure
Storm names can draw inspiration from natural phenomena, infrastructure, or landmarks. Names like "Ragingbull," metaphorizing the powerful and relentless bull, illustrate a storm's fury. "Tropopause" and "Mesocyclone" are direct references to meteorological phenomena, highlighting the scientific origins of some storm names.
Infrastructure-related names like "Blazar" (a reference to blazing speed), "Subduction" (for plate tectonics), or "Fenway" (the iconic baseball stadium in Boston) showcase the diverse and creative sources behind storm names. Some names, like "Tesla," might not directly relate to storm characteristics but represent technological advancements or prominent figures, adding an intriguing layer to the storm naming process.
As we continue to learn about and navigate these titanic forces of nature, storm names serve as a compelling reminder of our relationship with the environment and our collective need for preparedness, understanding, and resilience. So the next time a powerful storm system is brewing, take a moment to appreciate the story behind its name and the unique way it connects us to our world's dynamic weather systems.
