What dictates a hurricane’s strength?
There are many ways to categorize a hurricane. The storm’s central pressure is one way. The height of its storm surge is another. How much rain it drops is another. And, of course, the strength of its wind is another. But what causes a hurricane to strengthen or weaken? The answer is simple enough, but multifaceted.
"Alarming year for extremes": 2021 saw record-high greenhouse gas, ocean heat and sea levels rise, new report finds
"With many communities hit with 1,000-year floods, exceptional drought and historic heat this year, it shows that the climate crisis is not a future threat but something we must address today," one NOAA administrator said.cbsnews.com
Managers of New York Fish Dealer Plead Guilty to Fishing Fraud Conspiracy
On April 20, a federal grand jury indicted Christopher Winkler, Bryan Gosman, Asa Gosman and Bob Gosman Co. Inc. with one count of conspiracy, among other crimes. Bryan and Asa Gosman admitted that this fish was then sold to a now-defunct company, an unindicted co-conspirator, in the New Fulton Fish Market in the Bronx, New York. Both Asa Gosman and Bryan Gosman had an ownership interest in the defunct company. In court documents, Bryan and Asa Gosman admit that the sales of illegal fish (to both companies) totaled at least $240,000 wholesale. Bryan and Asa Gosman stated that part of the conspiracy was to falsify both FVTRs and dealer reports to cover-up the fact that fish were taken in excess of quotas.justice.gov
Atlantic hurricane season shows no signs of slowing
We’re two months into the 2021 Atlantic hurricane season and atmospheric and oceanic conditions remain conducive for an above-average hurricane season, according to the annual mid-season update issued by NOAA’s Climate Prediction Center, a division of the National Weather Service.
NOAA hikes hurricane season ‘average’ to reflect more storms
The numbers 12-6-3 have been ingrained in meteorologists’ minds for a decade as the average numbers for tropical activity each year. Typically 12 tropical storms develop on average, with six becoming hurricanes and three becoming major hurricanes.
Timeline for climate change is moving
Forthcoming new normals for winter temperature are different from the current normals, which cover 1981-2010. NOAA’s database of “climate normals” is being updated with the results expected to be released May 1. Climate normals provide the baseline for comparing U.S weather and climate to the recent past. Rain totals in north Florida will be up to 5% less under the revised climate range. (noaa)New with this update will be additional monthly temperature normals for hundreds of U.S. stations with shorter 15-year averages.
NOAA upgrades US weather forecast model
JACKSONVILLE, Fla. – NOAA is upgrading its Global Forecast System (GFS) weather model to boost weather forecasting capabilities across the U.S. These advancements will improve hurricane genesis forecasting, modeling for snowfall location, heavy rainfall forecasts, and overall model performance. Coupling the GFS and wave models will streamline the National Centers for Environmental Prediction (NCEP) production suite by consolidating atmospheric and wave forecast data and distributing them together. Ad“This substantial upgrade to the GFS, along with ongoing upgrades to our supercomputing capacity, demonstrates our commitment to advancing weather forecasting to fulfill our mission of protecting life and property,” said Louis W. Uccellini, Ph.D., director, NOAA’s National Weather Service. Learn more about previous GFS upgrades and the history of the FV3 dynamical core at NOAA.
NOAA to test drones that could improve hurricane forecasts
Snapshot of the drone being released from the Hurricane Hunter Aircraft (NOAA)JACKSONVILLE, Fla. – We might still be a few months away from the start of the 2021 Atlantic Hurricane season, but NOAA is working on new ways to gather data within storms. During the 2021 season, NOAA will be testing a new drone that can fly at the surface of the storm and give scientists a batter understanding of the winds before landfall. “We should be able to give a better depiction of what the winds are in that lowest layer that the Hurricane Center could use in its immediate forecast for the public,” said Dr. Joseph Cione, with NOAA. “So far, everything looks really, really good, and we’re pleased with the results,” said NOAA Corps Lt. Cmdr. “There’s actually a couple different ways we can control it,” Abitbol said.
2020 ties 2016 as Earth’s warmest year
Higher than normal temperatures are shown in red and lower than normal temperatures in blue. A European climate center revealed that globally 2020 was tied with the previous warmest year -- 2016 -- making it the sixth in a series of exceptionally warm years starting in 2015. In addition, NOAA said Friday the average temperature across the contiguous U.S. in 2020 was 54.4 degrees F (2.4 degrees above the 20th century average), making 2020 the fifth warmest year on record. There were no areas of below-average annual temperatures observed across the lower 48 states during 2020. AdMeanwhile, Europe saw its warmest year on record, 0.4°C warmer than 2019, which was previously the warmest year.
A new whale species discovered in the Gulf of Mexico
Gulf of Mexico Bryde’s whale is listed under the Mammal Protection Act. A new whale species has been discovered in the Gulf of Mexico. NOAA Fisheries scientists published a paper showing that the Bryde’s (pronounced “broodus”) whale is actually a new whale species. The discovery comes after decades of research on endangered Bryde’s species living in the Gulf of Mexico. He was the first researcher to recognize that Bryde’s whales (now Rice’s whales) are present in the Gulf of Mexico,” NOAA said.
NOAA satellites helped save 304 lives last year
Of the 304 U.S. rescues last year, 217 were water rescues, 12 were from aviation incidents and 75 were from events on land. Florida had the most SARSAT rescues with 67, followed by Alaska with 29. The record for the most SARSAT U.S. rescues in one year was set in 2019, with 421. (NOAA) (NOAA)When a NOAA satellite pinpoints the location of a distress signal in the U.S., the information is relayed to the SARSAT Mission Control Center at NOAA’s Satellite Operations Facility in Suitland, Maryland. NOAA also supports rescues globally by relaying distress signal information to international SARSAT partners.
12th right whale calf spotted this season
A 19-year-old right whale known as Infinity and her first calf were sighted Sunday off Amelia Island. Another right whale calf was spotted this year with its mother off the coast of Northeast Florida. So far, there have been 12 calves sighted this right whale season, NOAA said. NOAA said 13-year-old Bocce and her second calf, as well as a 20-year-old right whale and her third calf, were seen Wednesday. If you’re along the coast and see a right whale and it’s a calf, it’s very important to give them space -- 500 yards to be exact.
2 right whale calves spotted off coast of Northeast Florida
Two right whale calves and their mothers were spotted last week off the coast of Northeast Florida. So far, there have been seven calves sighted this right whale season, according to the National Oceanic and Atmospheric Administration Fisheries Southeast. On Friday, a right whale known as Minus One and her new calf were sighted off South Ponte Vedra Beach. A right whale known as ‘Minus One’ is a mom again! Right whales are an endangered species that usually migrate south along the Georgia and Florida coastline to give birth to their calves.
New right whale spotted off Georgia coast
“Nauset’’ & her new calf were sighted off Sapelo Island, Georgia, yesterday. VILANO BEACH, Fla. – We have another right whale baby sighting! Weeks after the first two calves of the season were sighted off the coasts of Florida and Georgia, another baby was spotted Monday, according to NOAA. She and the little one were spotted off Sapelo Island, Georgia. We have a new right whale!
