← GeographyWhich atmospheric phenomenon results when Coriolis force deflects geostrophic winds around a high-pressure system at altitude?
A)Formation of a blocking anticyclone✓
B)Development of a katabatic wind
C)Intensification of orographic lift
D)Exacerbation of valley fever outbreaks
💡 Explanation
When geostrophic winds, balanced by pressure gradient and Coriolis forces, encounter a high-pressure system, the Coriolis force deflects them in a clockwise direction (Northern Hemisphere), reinforcing the high thus forming a blocking anticyclone. Therefore, a blocking anticyclone results, rather than katabatic winds, orographic lift, or disease spread, which arise from different mechanisms.
