Record Wind Speeds from Hurricane Melissa Confirmed

During a recent mission to Hurricane Melissa, researchers recorded an astonishing wind speed of 252 miles per hour using a dropsonde deployed from a NOAA Hurricane Hunter plane. This measurement marks the strongest wind speed ever documented for a hurricane.

This incredible gust surpassed the previous record of 348 mph set during Typhoon Megi in the western Pacific Ocean back in 2010.

The U.S. National Science Foundation’s National Center for Atmospheric Research (USNSF NCAR) was responsible for verifying these impressive wind measurements. This institution has been integral to the development of dropsonde technology over the years, and continues to be the sole provider of these operational devices worldwide.

Dropsondes, which are about the size of a Pringle can, are launched from research aircraft into tropical storms to gather essential data such as barometric pressure, humidity, temperature, and wind speed. This information is critical for improving storm prediction models.

As a series of dropsondes were released from a Hurricane Hunter aircraft en route to Hurricane Melissa, researchers noticed something extraordinary: the recorded wind speeds were the highest ever acquired by a dropsonde, according to USNSF NCAR.

The National Hurricane Center, which received these potentially record-breaking statistics via satellite, promptly reached out to the researchers at USNF NCAR for verification.

After conducting a series of rigorous tests on the dropsonde data, researchers confirmed the record-breaking nature of the winds. It’s important to validate such measurements carefully, as previous records have sometimes been discarded due to not meeting established standards.

For instance, Hurricane Katrina’s winds were initially thought to be record-breaking, but discrepancies in the recording process ultimately led to their rejection.

Once deployed, a dropsonde opens a parachute and takes measurements two to four times every second while slowly drifting through the storm, allowing forecasters to gather vital statistics for tracking the hurricane’s path and issuing timely warnings.

The 252 mph wind speed was recorded just before the dropsonde fell into the Atlantic Ocean, a perilous area where it would have been nearly impossible to measure wind speeds otherwise.

This latest feat in wind measurement adds to the already alarming profile of Hurricane Melissa, a Category 5 hurricane that stands as one of the most severe Atlantic storms on record.
