Which climate outcome results when a meandering jet stream amplifies atmospheric blocking over major river systems?

💡 Explanation

Amplified blocking hinders the eastward progression of weather systems; therefore, prolonged precipitation over river basins causes riverine flooding events downstream. This is due to atmospheric Rossby waves, rather than causing desiccation or glacial retreat which depend on other conditions.
