Most of the time there are two jet streams in each hemisphere; a sub-tropical and a sub-polar one. All are caused by a cold air mass being next to a warm one. Surface pressures and winds are more irregular and harder to forecast than those in the upper atmosphere. By the time you get to jet stream altitude, 30 000 feet or higher, you rarely see cut-off lows and anticyclones. The upper wind pattern is a wavy west to east airflow, caused by the temperature gradients between the tropics and the poles. The jet streams are very strong compared with surface winds because the higher you go, the bigger the contribution of temperature gradients to wind circulation. So the atmosphere is a heat engine, converting temperature differences into the kinetic energy of the winds. Above the jet streams you enter the stratosphere, which is at a more or less constant temperature, so the winds drop again.

That is not true about the toilet water and drains spinning in the opposite direction in the southern hemisphere. The Coriolis effect only occurs in large scale systems and with air travel.

Yes there is, but everything goes the opposite
way. Even the toilet water goes clockwise while
ours goes counter clockwise when flushed.
