Which outcome occurs when increased atmospheric temperature gradients affect large-scale airborne volcanic ash dispersion?

💡 Explanation

Modified ash cloud trajectories result, because temperature gradients enhance the pressure gradient force, affecting the prevailing winds steering the clouds via the Coriolis effect. This alteration guides ash clouds differently, therefore changing deposition patterns, rather than just plume density or particle size changes.
