by Washington (AP) – Incredible amounts of moisture in the air cheered on a storm that hardly moved over central texas, which in the early morning conditions created conditions for fatal floods when it was easy to catch people surprisingly, said meteorologists.
Over a period of several hours in the early Friday, more than 12 inch rain in Texas Hill Country fell in Texas Hill Country, which according to the weather forecast Accuweather rose. The area is of course susceptible to floods, but this was a particularly bad storm that hit during the vulnerable accommodation hours, experts said. More than two dozen deaths were reported together with numerous rescues.
Meteorologists said that a man -made climate change has more moisture and bad storms can take more rain, although it is difficult to connect certain storms to a warming planet so soon after their appearance.
“In a warming climate, we know that the atmosphere to give more moisture, capture and then publish. But what we know about climate change is that our regulations are not as uniform as before,” said Shel Winkley, a meteorologist with a climate -centrally. “So you will enable these major regeneration in localized areas and open up the historical level of moisture in the atmosphere.”
In the past few weeks, Texas and West Virginia, which were driven by heavy rainsters, have been fatal. In June, more than 7 inches (18 centimeters) fell over a period of hours in San Antonio, which caused dozens of rescues before the rapid rapid flood and killed at least 13. This month, at least nine people fell in West Virginia when the rain died up to 4 inches (10 centimeters), within 40 minutes and caused flood flooding in footwear in 40 minutes.
Seasoning rain runs from hard ground
Robert Henson, meteorologist and writer at Yale Climate Connections, said that this youngest rainstorm in Texas was about a unique event in the generation. It fell into the Texas hills, in which water quickly shoots rough hills into narrow river basins that swell quickly.
“As is so often the case with the worst disasters, many things came together in a terrible way.” Said Henson.
In addition, the area was in a drought so that the water ran down the dry, hard country quickly. This made it more dangerous for children who visited the camp.
“A sudden rainy petration like this will be more difficult to be absorbed,” said Brett Anderson, a high -ranking meteorologist at Accuweather. “It just runs right away. It’s like concrete.”
The amount of rain was overwhelming. Former Noaa chief scientist Ryan Mue, a private meteorologist, calculated on Saturday morning that the storm on Kerr County had dropped 120 billion gallons water that received the main load of the storm.
A storm with a lot of fuel
Moisture promoted the storm from many directions. The tropical storm Barry formed briefly last weekend and moved over Mexico and then his remains continued to Texas. But the jet stream, an air flow that moves weather pattern, was not there to push this moisture away.
“Usually weather systems and the remains of tropical systems are picked up by the jet stream, and that is currently not about Texas,” said Winkley, the meteorologist of Climate Central. “It is essentially a weather system without a way to escape the Lone Star State.”
The warm water of the golf fueled the moist atmosphere. Even more moisture came from areas over the Pacific in the West. The combination gave the storm a lot of fuel when it started.
Winkley said that the area in which was flooded could mean climate change that rainstorms are less common, but if they occur, they can be more serious.
In general, a warmer atmosphere can absorb more moisture and create conditions for storms to fall more rain.
“With climate change, we have a warming atmosphere. A warmer atmosphere keeps a lot more moisture, and in recent years we have obviously seen much more total atmosphere than normally,” said Anderson, the Accuweather meteorologist.
