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.

• After a prolonged drought, which outcome results due to dry aeolian processes?
• Which increased risk occurs to structures founded atop loess deposits during prolonged saturation events?
• Which volcanic outcome results following increased magma hydration?
• Which risk increases when mafic lava viscosity decreases?
• Which hazardous outcome dramatically increases after pyroclastic flows destabilize steep volcanic slopes?
• Which outcome occurs following substantial coastline erosion near sea stacks?
