Oceanographers have found that a hurricane can be considerably strengthened in the Gulf of Mexico through the compounding effects of two extreme weather events. This process could continue in the future as ocean temperatures continue to rise around the world, according to a study co-authored by a Texas A&M University at Galveston professor.
Kyeong Park, professor and head of the Department of Marine and Coastal Environmental Science at Texas A&M-Galveston, and colleagues have had their work published in Nature Communications.
The team examined Hurricane Michael, the first Category 5 hurricane on record to impact the Florida Panhandle, in October 2018. Prior to Hurricane Michael, Tropical Storm Gordon in early September mixed cold bottom water with warm surface water, lowering the surface water temperature and increasing the capacity of absorbing more heat.
During the subsequent atmospheric heatwave, the water column could absorb more heat energy resulting in a marine heatwave,
The vast majority of hurricanes develop from disturbances that blow off the west coast of Africa on the prevailing winds. They form into low pressure systems and storms as they cross the tropical Atlantic into the warmer waters around the Caribbean and Gulf of Mexico.
But this season, six storms — Arthur, Bertha, Fay, Omar, Isaias and Sally — either formed or strengthened in the coastal region between Florida and the Carolinas. Four of them had nontropical origins:
Tropical storms Arthur and Bertha both formed in May, before the official June start of the Atlantic hurricane season, off the Florida and South Carolina coasts.
Tropical storms Fay (July 9) and the short-lived Omar (Sept. 1) both formed off the North Carolina coast.
Meanwhile, hurricanes Isaias (July 30) and Sally (Sept. 14) were the remnants of African waves that strengthened in the warm waters just south of Florida before taking their
A lot can go wrong when hurricanes stall. Their destructive winds last longer. The storm surge can stay high. And the rain keeps falling.
During Hurricane Sally, Naval Air Station Pensacola reported more than 24 inches of rain as the storm’s forward movement slowed to walking speed along the coast. We saw similar effects when the decaying Hurricane Harvey sat over Houston for four days in 2017 and dropped up to 60 inches of rain in some areas – that’s 5 feet! Hurricane Dorian slowed to 1 mile per hour in 2019 as its winds and rain battered the Bahamas for two days.
Post-Tropical Storm Beta was the latest stalling storm, flooding streets in Houston as it slowly crept up the Texas coast
Despite COVID-19 limitations and planning challenges caused by Hurricanes Laura and Marco, a collaborative team prevailed in conducting a live Advanced Naval Technology Exercise (ANTX).
Naval Surface Warfare Center Panama City Division (NSWC PCD) recently collaborated with Commander, Naval Meteorology and Oceanography Command (CNMOC) in coordination with the Naval Oceanographic Office’s Fleet Survey Team (FST), and Klein Marine to conduct the testing at NSWC PCD.
The government and industry teams overcame potential setbacks by implementing safety protocols, maintaining a flexible schedule, and keeping a can-do attitude. With participants coming from across the country, one team travelling over 40 hours by vehicle, to both Gulfport, Miss., and Panama City, Fla., this synergy led to successes that far outweighed the struggle.
“The ANTX 20 vignette highlighted technology that is important to the Navy in maintaining a warfighting edge,” said Capt. Micah Weltmer, CNMOC ANTX director.
Get Tim Cook talking about privacy, renewable energy or even the coronavirus pandemic, and he’s happy to give you his perspective. Talk about President Donald Trump, and he almost immediately wants to change the topic.
The dynamic played out several times with Cook, who participates in only a handful of interviews per year, while talking with the Atlantic’s editor-in-chief, Jeffrey Goldberg, in a video-recorded interview Monday.

Goldberg asked about Cook’s conversations with Trump, who’s invited the Apple CEO to White House events on manufacturing and the economy. Cook said he didn’t want to share them out of respect for Trump’s privacy. Goldberg asked how Cook would rate America’s response to the coronavirus. Cook once again declined.
