In a recent report by Yale Climate Connections, Hurricane Otis, which made landfall in Acapulco, Mexico on October 25th, recorded a wind gust of 205 mph (330 kph), potentially ranking among the top 15 strongest wind gusts ever measured worldwide. The gust was detected at the port authority in Acapulco Bay, marking it as a significant meteorological event.

Hurricane Otis, classified as a Category 5 hurricane with sustained winds of 165 mph, caused widespread impact and devastation upon reaching land. However, it was the exceptional wind gust recorded at the port authority that has captured the attention of meteorologists and climate researchers. The wind gust was measured 15 minutes after the National Hurricane Center declared the storm's landfall, raising questions about accurate and timely reporting.

Officials from the Mexican National Tidal Service revealed data captured by one of their instruments situated in the right-front eyewall of Hurricane Otis. The instrument measured a sustained wind speed of 114 mph, with gusts reaching an astonishing 205 mph. The measurements align with expectations of intense wind in the eyewall region, where wind speeds are typically the strongest.

While the measurements are notable, the accuracy of the data has been scrutinized due to the height of the measurement tower. The tower appeared to be shorter than the standard height of 10 meters used for wind measurements, which suggests that the recorded winds may have been affected by surface friction. Despite this limitation, the site's exposure was deemed adequate, located at the end of a pier with no major obstructions, allowing for a more accurate reflection of the wind's strength.

Evaluating extreme wind measurements can be challenging due to the destructive nature of such high winds. Normally, winds of this magnitude would disable equipment and disrupt communications, making accurate measurements rare. Only about 15 measurements of wind gusts exceeding 190 mph exist, and some of them have limited documentation, casting doubt on their validity.

It is worth noting that wind speeds atop hills or mountains can be significantly higher than those recorded on flat terrain. Studies have shown that mean wind speed-ups of up to 90% have been observed on the crests of hills, compared to measurements taken on flat terrain. This phenomenon indicates that wind gusts recorded on elevated topographic features may experience acceleration, contributing to higher wind speeds.

In light of these considerations, Yale Climate Connections provides a list of the top 15 recorded wind gusts worldwide. The list includes data from various sources, such as the Taiwanese island of Lanyu, which holds three top spots. Lanyu's measurement site is located on a hill with an elevation of 325 meters (1,066 feet), suggesting wind acceleration at higher elevations.

Hurricane Otis's inclusion on this list underscores the significance of the wind gust recorded in Acapulco. Despite the potential limitations in measurement accuracy, the event serves as a reminder of the immense power and destructive potential of hurricanes. The findings also demonstrate the ongoing need for continued research and understanding of extreme weather events in the era of climate change.
