State the mechanism for developing mid-latitude cyclonic and anticyclonic storms
What will be the ideal response?
?
ANSWER: When upper-level divergence is stronger than surface convergence (more air is taken out at the to than is brought in at the bottom), surface pressures drop, and the low intensifies (deepens). By the same token, when upper-level divergence is less than surface convergence (more air flows in at the bottom than is removed at the top), surface pressures rise, and the system weakens.
When upper-level convergence of air exceeds low-level divergence (inflow at top is greater than outflow near the surface), surface pressures rise, and the anticyclone builds. On the other hand, when upper-level convergence of air is less than low-level divergence, the anticyclone weakens as surface pressures fall.
