OCEAN 210 Lecture Notes - Lecture 12: Coriolis Force, Ekman Transport, Downwelling
Document Summary
All diagrams taken from "ocn210_topic2_lect1. ppt" on the course canvas website or created by me. No midterm due to missed lectures from snow days- just final. Velocity, momentum, and force: velocity measures the motion of an object in units of distance/time. Without a force, momentum is conserved (newton"s law). For a fixed mass it is the velocity that changes: acceleration: a vector because it has a direction, force = mass * acceleration. Force: since they have direction, they cancel each other out, force = mass * acceleration, force = mass * velocity. = f1 + f2: f = (m x v) Friction: direction depends on the velocity of the object, no single direction like gravity, drag force (water) is opposite of velocity. Coriolis force: motion in rotating earth appears to deflect to the right in the northern hemisphere, to the left in the southern hemisphere.
