temperature gradients between different air masses
Jet streams form where large horizontal temperature contrasts exist (for example along the polar front). Those strong temperature differences create strong pressure gradients aloft; combined with the Coriolis effect from Earth's rotation, the resulting winds are concentrated into narrow, fast-flowing bands (the jet streams). The other choices (magnetic field, ocean currents, the Moon's gravity) are not the primary drivers.
