Hurricane Melissa’s wind gusts reached a record-breaking pace shortly earlier than the storm made landfall within the Caribbean final month, in keeping with information recorded in the course of the lethal occasion.
The information was collected when a NOAA Hurricane Hunter airplane dropped a fleet of climate devices into the raging storm, in keeping with a information launch from the U.S. Nationwide Science Basis Nationwide Heart for Atmospheric Analysis. The units, referred to as dropsondes, have small parachutes hooked up and between two and 4 readings per second earlier than falling into the ocean.
Dropsondes are the one units that may file data on stress, temperature, humidity and wind without delay. The information is utilized in forecasts and climate warnings, together with emergency alerts.
“Whenever you’re a class 4 or 5 hurricane, you are not going to have an airplane flying that near the floor – that will be completely unsafe – however that you must know what is going on close to sea stage as a result of that is the place folks and property are most affected,” stated NSF NCAR engineer Terry Hock, who manages the Dropsonde program, within the information launch. “The dropsonde will get you data you may’t get some other method and that is why it has been round for many years.”
One dropsonde used throughout Hurricane Melissa clocked a wind gust of 252 miles per hour shortly earlier than falling into the ocean.

NOAA researchers contacted the NSF NCAR to substantiate that it was the very best wind pace ever recorded by a dropsonde.
“NOAA looped us in after they noticed the excessive wind pace and requested, ‘Are these numbers any good?'” stated Holger Vömel, an NSF NCAR senior scientist who works with the group’s Dropsonde Program.
To confirm the information, Vömel and different researchers reviewed the numbers with a high quality management software program. In addition they confirmed that the reported 252 mile wind gust would have been bodily potential, and that it tracked with the hurricane’s habits, in addition to earlier storm patterns. The evaluate confirmed that the wind gust measurement was correct.
The earlier quickest wind gust recorded by a dropsonde was in 2010, when Hurricane Megi unleashed a 248 mile per hour blast whereas over the western Pacific Ocean. Throughout Hurricane Katrina, researchers thought they’d recorded an excellent stronger gust, however the information had substantial points, the NSF NCAR stated.

“They’ve pilots and researchers actually placing their lives on the road to get these measurements. They’re the heroes, and it is a privilege we get to play a task in ensuring the measurements they purchase are correct,” Vömel stated.
Hurricane Melissa inflicted catastrophic harm within the Caribbean in late October. It made landfall in Jamaica as a Class 5 storm earlier than progressing in direction of Cuba, the Bahamas, the Dominican Republic and Haiti. Dozens of individuals, largely in Jamaica and Haiti, had been killed within the storm.
