Study finds humans are directly influencing wind and weather over North Atlantic

A new study led by scientists at the University of Miami (UM) Rosenstial School of Marine and Atmospheric Science provides evidence that humans and the air in the eastern United States and Western Europe by releasing CO2 and other pollutants into the Earth’s atmosphere Weather patterns are affected.

In the new paper published in the NPJ Climate and Atmospheric Science Journal, the research team found that a significant weather event change in the North Atlantic over the past 50 years — known as the North Atlantic oscillation — can be traced back to human activities. is. Which affects the climate system.

“Scientists have long understood that human actions are warming the planet,” said the study’s lead author, Jeremy Culvans, a UM Rosenstial School alumnus. “However, it is very difficult to identify a human-induced signal on weather patterns.”

“In this study, we show that humans are influencing weather and climate patterns over the Atlantic, and we may be able to use the information that weather and climate changes are predicted up to a decade ago, “Culwens said.

North Atlantic oscillations, a result of air pressure fluctuations throughout the Atlantic, affect weather by affecting the intensity and location of the jet stream. Europe, Greenland, Northeast US of this oscillation. And the winter season in North Africa and in the North Atlantic has a strong impact on crop yields and quality of productivity.

The researchers used several large climate model assemblies, compiled by researchers at the National Atlantic Center for Atmospheric Research, to predict the North Atlantic Oscillation. The analysis included 269 model runs, which is over 14,000 simulated model years.

On March 25, the study was published in The NPJ Climate and Atmospheric Science Journal titled “NOO Predictability from External Forcing in the Late Twentieth Century”. The authors of the study include: Kelvans, Amy Clement and Lisa Murphy from UM Rosenstial School, and Mark Kane from Columbia University’s Lamont-Doherty Earth Observatory.

The study was supported by the National Science Foundation (NSF) Climate and Large-Scale Dynamics Program (grants # AGS 1735245 and AGS 1650209), NSF Paleo Perspectives on Climate Change Program (grant # AGR ​​1703076), and NOAA’s Climate Variability and Predictability Program it was done.

In the new paper published in the NPJ Climate and Atmospheric Science Journal, the research team found that a significant weather condition change in the North Atlantic over the last 50 years – known as the North Atlantic oscillation – can be detected. Human activities that affect the climate system.
