Which outcome results when persistent high pressure blocks atmospheric rivers?

💡 Explanation

Prolonged drought happens because blocking redirects or weakens atmospheric rivers distributing moisture; a phenomenon described as atmospheric blocking. Blocking prevents precipitation, therefore droughts occur rather than glacial melt or erosion which need water action.
