:: : : : : : No, jet streams aren't caused by friction with the ground, they are what happens to the atmosphere far from the frictional effect of the surface.

While proximity to land usually causes weakening in hurricanes, occasionally the frictional effects of the wind right on the coast can temporarily give an extra lift to thunderstorms surrounding the eye, causing the storm to strengthen.

Soon, PAGASA downgraded Wilma to a low-pressure area at 09 : 00 UTC . Interacting with the frictional effects by passing through the Philippines, the tropical depression still got slightly organisational improvement, and it began to accelerate westward.

If we assume that the rail gun is above the CG for the ship, then the ship should roll somewhat, then roll back the other way, and back again, less with each roll and counter-roll due to frictional effects.

Over time, the accumulation of biofoulers on hulls increases both the hydrodynamic volume of a vessel and the frictional effects leading to increased drag of up to 60 % The additional drag can decrease speeds up to 10 %, which can require up to a 40 % increase in fuel to compensate.

Frictional effects from the machine s grip on the conductor can be used to counter this to some degree, but in practice it is insufficient and the required stability can only be achieved by having a relatively large weight suspended rigidly below the conductor from the non-rotating part of the wrapping machine.
