â GeographyWhich mechanism increases tropical cyclone intensity as they drift poleward?
A)Strengthening Coriolis effect on rotating windsâ
B)Decreasing sea surface temperatures inhibiting evaporation
C)Reduced vertical wind shear disrupting storm structure
D)Increased landmass interaction causing rapid dissipation
ð¡ Explanation
As tropical cyclones move poleward, the Coriolis force increases because it is proportional to the sine of the latitude, enhancing the cyclonic rotation and leading to a tighter, more intense storm. Therefore a strengthening Coriolis effect increases intensity, rather than SST decrease, reduced shear, or land interaction which weaken storms.
