A hot storm like Hurricane Ida it can lead to flooding, causing disruption, damage, and loss of life. Like many other types of weather, torrential rains and hurricanes in the US East Coast have become more severe in the last few decades. Although there is more controversy at the rate of increase in energy, there is evidence that such storms are moving more slowly than ever before. This slow motion makes the storm longer and more productive heavy rain. However, since the history of the weather dates back to 1948, it is not known whether the slow-moving storm is comparable to that of the past.
A recent research answers that question by using wooden rings to repair hundreds of years of hurricane season. The study trees, some more than 300 years old, show that rainfall has increased by 2 to 4 millimeters in a decade, leading to an increase of 128 mm (5 inches) compared with the early 1700s. Significant increases have taken place in the last 60 years, and recent protests may not be the same as in the past.
Continuing to establish these ancient reconstruction records, researchers are working with these data to help predict what the region can expect in the future.
The Benefits of Growing Up — At least Trees
In one of his novels, Justin Maxwell and his associates discovered that tall pine trees The east coast of the US can serve as a sign of a hurricane, as trees move toward the end of the season (June to October). This little experiment shows that recent rains were far greater than any other tree ever experienced in their lifetime.
This is to be expected, because valuable records often show evidence of the worst weather in their entire history, although they are often different. The discovery sparked new research, which looked to see if this approach could spread to more places.
“In many cases, rebuilding wooden rings shows us that the worst weather we have ever recorded with weapons (weather forecasts) over the last 120 years has been a long time,” Maxwell told Ars Technica. “Our previous research showed that recent strikes were not the same as in the past – the highest rates are from the 1990’s, which was surprising, and encouraged us to test a larger area to see if the increase was local or recent.”
Combining existing data with two new locations, the researchers included prices from seven locations in North and South Carolina. North America is the region with the highest rainfall, and it has the highest rainfall in the world.
The new data included a selection of models from 13 to 36 old-growth trees per site (taken in a way that slightly damaged the trees), as well as stumps. The researchers’ result was to modify their model by comparing the types of tree rings with known rainfall patterns from 1948 to the present.
Restoring the Past to Predict the Future
As might be expected, tree rings represent a seasonal rainfall more than the amount of a hurricane or its end. But larger measures are showing that the storm season has slowed down many years ago.
A rainy season does not mean that a severe storm has passed. “[It] it could represent the effects of one storm or another, ”wrote Maxwell. “What we have found in this article is that the region is receiving the heaviest hurricane season.” Although researchers in the field are still debating why, many say that it is related to the slow-moving storm in the area.
