Ahoy, mates! Storm downed ships manifest history
#Cosmoread: Tree-ring data in the ancient Spanish ships and unusually low hurricane activity showed a “Golden Age of Piracy,” new research suggests.
The lull in the storm, which occurred during the 18th and 19th centuries, partly a drop in sunspot activity, solar radiation to reach the Earth may have been caused by the low, the researchers found.
“We are the first to study the storm in the past to use the ships are,” lead author Valerie Trouet, Tree Ring Research at the University of Arizona lab dendrochronologist, said in a statement. “Tree-ring data and combining data shipwreck, we are extending back in time to record the Caribbean storm, and that improves our understanding of hurricane variability.”
The new data could help researchers understand how the storm pattern will change as the climate warms, the researchers said.
Trouet said he and his colleagues for the first tree-ring researchers got the idea while at a conference. Trouet at the meeting mentioned that the National Hurricane Center only began tracking hurricanes in the Caribbean in 1850; it is difficult to understand how climate change affects hurricane season was making. But one of its partners, Hattiesburg Southern Mississippi University Grants Harley dendrochronologist, in the Florida Keys, the tree-ring data to 1707 people and was going back because of the storm could stunt the tree, those hurricane intensity can be gleaned from tree ring.
Then another colleague, Lugo, Santiago de Compostela University in Spain Marta Dominguez-Delmas, said she dated old ships by analyzing tree rings in the wood found under the water. Tree-ring data from the team thought that maybe ships Caribbean hurricane history of the region could be pushed back further in time.
(Dover, 2011) and “ships of Florida: A Comprehensive List”: such “major shipwreck in the Western Hemisphere to American ships as a complete guide” – the researchers dug classic books (Pineapple Press 2015) – to amass a detailed record of the Caribbean ships.
From there, the scientists analyzed the log ship that Spanish vessels between 1495 and 1825 to identify during the storm worsened.
It was a period between 1707 and 1825, 75 per cent in the number of hurricanes has some sunspots, known as the Joint, historical accounts, as well as tree-ring data from the actual storm data from the Caribbean ships, the same trend Maunder minimum detected. Without these sunspots, the Earth received less sunlight rays, leading to a cooler Northern Hemisphere, the researchers of the journal Proceedings of the National Academy of Sciences on Monday (March 7) reported.
Changes in understanding how heat affects of the hurricane season in the past in modern times can help with regional storm prediction models, the researchers said.
