PowerPoint Presentation - NATS 101, Section 16 Lecture 11 Upper-Air Winds

Summary

ĄCurved Flow

Requires Centripetal Acceleration

Difference between PGF and Coriolis Force

Speed Changes => Convergence-Divergence

ĄFrictional Force

Causes Winds to Turn toward Low Pressure Important in the lowest 1 km above the Surface Leads to Convergence-Divergence

ĄCurvature and Friction

Leads to Vertical Motions
