Westerly winds play an important role in changing weather and climate both locally and globally.
Typically westerly winds blow from west to eastthrough the Earth's mid-latitudes. But scientists have noticed that over the past few decades these winds have been changing, migrating towards the poles. Research shows this is due to climate change.
Scientists debate whether westerly winds will continue to move poleward as temperatures and carbon dioxide (CO2) rise further in future warming scenarios.
A New Method for Tracing Ancient Western Historywinds are an indirect indicator of what awaits us as a result of rising global temperatures. Lead author Lamont graduate student Jordan Abell and his advisor Gisela Winkler developed a way to apply paleoclimatology—the study of past climates—and found evidence suggesting that atmospheric circulation patterns will change as the climate warms.
Dust deposits in the world's oceans contain recordspast climatic conditions in their layers. Based on it, researchers were able to reconstruct the nature of the winds that blew on Earth approximately three or five million years ago.
The movement of these winds is of great importance tostorm systems and precipitation regime. Although this study does not indicate exactly where it will rain, it does confirm that the pattern of wind and rainfall will change as the climate warms.
