Scientists want to introduce ‘Category 6’ for hurricanes

In recent years the planet has faced a significant increase in extreme weather events; Hurricanes are at the forefront of their destructive capacity. For this reason, scientists want to introduce a new classification: category 6emerged after observing hurricanes of extraordinary and unprecedented intensity..

The new classification follows five devastating storms since 2013, each exceeding the maximum intensity of Category 5 on the Saffir-Simpson Hurricane Wind Scale.

The intensifying storm sparked controversy

The traditional scale shows hurricanes peaking at Category 5 with wind speeds reaching 252 kilometers per hour. Storms are known for their devastating effects, often making areas uninhabitable for long periods of time.

However, the recent storm surge has exceeded these figures, leading to a revision of the scale. Researchers observed wind speeds exceeding 309 kilometers per hour, marking a new era in storm intensity.

Hurricane Patricia, Typhoon Meranti, Typhoon Goni, Typhoon Haiyan, and Typhoon Surigae crossed this new threshold. In particular, Hurricane Patricia broke a record in 2015. The strongest tropical cyclone ever recorded in the Western Hemisphere, with wind speeds exceeding 346 kilometers per hour.

The role of climate change

The intensity of the storms is increasing. Climate change is a trigger that affects hurricanes and typhoons in various ways. Rising sea surface temperatures fuel these storms with more energy, causing them to increase in intensity and speed..

Additionally, it is possible that climate change will disrupt the movement of hurricanes, causing long-term destruction in certain regions.

Researchers such as Michael Wehner and James P. Kossin have emphasized the role of anthropogenic global warming in this trend. They point to increased ocean and air temperatures in tropical cyclone areas, contributing to increased potential wind intensity in these regions.

Call for recognition and preparation

Category 6 is not yet recognized by organizations such as the National Oceanic and Atmospheric Administration (NOAA). However, the debate on this issue is not new and is becoming more topical as the climate crisis deepens.

University of Otago Senior Lecturer Dr. Daniel Kingston emphasizes the importance of this categorization to effectively communicate the expected increase in tropical cyclone wind speeds due to climate change.
