Atlantic Ocean by three inter-connected currents: the Gulf Stream which flows north-east from the North American coast at Cape Hatteras; the North Atlantic Current, a branch of the Gulf Stream which flows northward from the Grand Banks; and the Subpolar Front, an extension of the North Atlantic Current, a wide, vaguely defined region separating the subtropical gyre from the subpolar gyre. This system of currents transport warm water into the North Atlantic, without which temperatures in the North Atlantic and Europe would plunge dramatically. North of the North Atlantic Gyre, the cyclonic North Atlantic Subpolar Gyre plays a key role in climate
Drift current same direction as the electric field, but the resulting conventional current points in the same direction as the electric field in both cases. If an electric field is applied to an electron in a vacuum, the electron will accelerate faster and faster, in approximately a straight line. A drift current looks very different than that up close. Typically, electrons are moving randomly in all directions (Brownian motion), frequently changing direction when they collide with grain boundaries or other disturbances. Between collisions, the electric field subtly accelerates them in one direction. So over time, they move at the drift velocity on
