Human-caused global warming will be associated with more extreme jet stream patterns, which will lead to more extreme weather, says a study published in Science Advances and released this week.
QRA is short for quasi-resonant amplification, which refers to extreme and unusual jet stream patterns.
The study mentions examples such as the 2003 European heat wave, the 2010 Pakistan flood and Russian heat waves, and the 2011 Texas and Oklahoma heat wave and drought.
Texas had its driest year on record in 2011, according to the National Weather Service.
The lack of rain that year put more than 97 percent of the Lone State State in a severe drought condition, according to the U.S. Drought Monitor.
A briefing for the Texas Legislature by the Office of the State Climatologist reported that the 2011 drought was “susceptibility due to global ocean temperature patterns.” The report added that while global weather patterns “tend to reverse themselves over time” in the future “the safest bet is that global temperatures will continue to increase, causing Texas droughts to be warmer and more strongly affected by evaporation.” These extreme weather events are likely to increase “under business-as-usual burning of fossil fuels, keeping in mind our assumption that the historically defined fingerprint remains valid in the future climate,” the study said.
But that figure varies among model simulations and could increase by even more, “roughly tripling” the number of events.
Although so much consistent rainfall can be concerning, National Weather Service meteorologist Lee Carlaw said it’s difficult to definitively connect two consecutive months of record-setting rain to something such as climate change.
