University of Arizona study links tree rings to climate extremes
A new study from the University of Arizona reveals how historical tree-ring data can help predict extreme summer weather events. Researchers, led by Ellie Broadman, analyzed tree rings to understand locked jet stream wave patterns, often preceded by La Niña winters, which can result in severe weather impacting agriculture and public health. … The study, published in AGU Advances, presents the first-ever reconstruction of historical jet stream patterns over the last 1,000 years. … The findings suggest that La Niña winters often lead to locked wave patterns in summer, offering a valuable tool for forecasting extreme weather.
