The gyres rotate counter clockwise in the Southern Hemisphere, and clockwise in the northern hemisphere.
In the Southern Hemisphere gyres flow in a counterclockwise direction.
Currents in the Southern Hemisphere move in a counter clockwise direction.
A typhoon in the northern hemisphere rotates counter-clockwise, in contrast to a typhoon in the southern hemisphere which rotates the other way (i.e., clockwise) as explained by the Coriolis effect.
For anything small (like a bathtub), it doesn't - that's an urban legend. The theory is that coriolis forces makes water swirl one way in one hemisphere and the opposite way in the other - but that force is quite utterly negligable on small amounts of liquid or gas - such as your bathtub. The effect DOES work at the scale of ocean currents and hurricanes. Hurricanes in the northern hemisphere rotate counterclockwise, those in the southern hemisphere (which are properly called "Typhoons") rotate clockwise. The coriolis force comes about because the earth rotates. If you think about a wind blowing south from somewhere far into the northern hemisphere, as the wind travels southwards, the planet rotates from west to east causing the air to be spun around in a counter-clockwise direction. The opposite happens in the southern hemisphere.
High air pressure systems spin clockwise.
All hurricanes and most tornadoes rotate counterclockwise.
Cyclones, mid-latitude and otherwise, in the Northern hemisphere rotate anti-clockwise, and cyclones south of the equator rotate clockwise.
Currents in the Northern Hemisphere move in a clockwise direction. Currents in the Southern Hemisphere move in a counter clockwise direction.
Tornadoes in the northern hemisphere rotate counterclockwise while those in the southern hemisphere rotate clockwise.
Winds in a tropical depression rotate counterclockwise if it is in the northern hemisphere and clockwise if it is in the southern hemisphere.
Counter-clockwise
No. Most tornadoes in the northern hemisphere rotate counterclockwise while most in the southern hemisphere rotate clockwise. Furthermore, a very small percentage (less than 1%) of tornadoes are anticyclonic, rotating in the opposite direction from what is normal in their hemisphere.
As with all low pressure systems the winds of a tropical depression rotate counterclockwise if it is in the northern hemisphere and clockwise if it is in the southern.
The toilet is too small a scale for water to certainly flush in one direction or the other because of the hemisphere they can, in fact, flush both ways. However hurricanes will rotate clockwise in the northern hemisphere and anit-clockwise in the southern hemisphere.
A typhoon in the northern hemisphere rotates counter-clockwise, in contrast to a typhoon in the southern hemisphere which rotates the other way (i.e., clockwise) as explained by the Coriolis effect.
If they both form in the northern hemisphere they will both spin counterclockwise. Ifg they both form in the southern hemisphere both will rotate clockwise.
