... Most of the motion in the ocean can be understood in terms of Newton’s Law that the acceleration of a parcel of water (how fast its velocity changes with time – du/dt) is related to the sum of forces acting on that parcel of water. We can split the forces, velocities and accelerations into south-nor ...

ESCI 107/109 – The Atmosphere Lesson 9 – Wind Reading
... Above the planetary boundary layer we can ignore friction. This leaves only two forces, PGF and CF. These two forces are usually very close to being in balance. This means that they must be acting in opposite directions. Since CF is always to the right of the direction of motion, then the PGF mu ...

... Nonviscous flow: The viscosity of a fluid is a measure of how resistive the fluid is to flow; viscosity is the fluid analog of friction between solids. An object moving through a nonviscous fluid would experience no viscous drag force—that is, no resistive force due to viscosity; it could move at co ...
