ATSC 113 Final Study (2022/2023) Already Passed Three main factors affecting wave formation: Wind velocity, fetch, duration. Wind velocity: Speed of the wind. Fetch: Distance over water wind can blow uninterrupted. Duration: Amount of time wind blows over water. If wind speed is slow, waves will always be _________, regardless of fetch or duration. Slow Drag: Frictional force acting against relative motion of one fluid with respect to another fluid. Describe drag between ocean and air. Tex...

any force has 2 measurable characteristics magnitude (size or strength) and direction Pressure Gradient Force (PGF) the gradient of any physical quantity is a measure of the difference in the value of that quantity at two different locations divided by the distance between those two locations PGF Equations X2 - X1 / D PGF moves from high pressure to low pressure isobars same pressure so PGF is perpendicular to isobars here Coriolis Effect the effect that ...
