Coriolis Effect (Weather)

Work in Progress

According to proponents of the Coriolis Effect, in the Northern Hemisphere wind systems rotate counter-clockwise, and in the Southern Hemisphere wind systems will rotate clockwise. This is provided as evidence of the Coriolis Effect, and therefore, as evidence of the diurnal motion of the earth.

Dr. Anantha Aiyyer of NC State University explains that systems should rotate counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.

=Prevailing Winds and Trade Winds=

"Prevailing Winds" and "Trade Winds" are the world's large permanent wind systems. When we look at the permanent wind currents of the world, we find the counter-clockwise rule of the Northern Hemisphere and the clockwise rule of the Southern Hemisphere to be untrue. Earth's large permanent wind systems are rotating in a manner contrary to the alleged Coriolis Effect.

=Hurricanes=

Coriolis Effect proponents point to the rotation of hurricanes. In the Northern Hemisphere hurricanes rotate counter-clockwise, and in the Southern Hemisphere hurricanes rotate clockwise, thus proving the Coriolis Effect. While researching this claim, we find that it may indeed be generally true for most hurricanes.

Counter-Rotating Vortexes
To explain why the hurricanes rotate oppositely from each other point to the fact that Hurricanes develop near the equator, and that at the equator there exists a strong wind current called the Equatorial Counter Current, which is a very strong permanent westerly-flowing wind current. This Counter Current runs in an opposite direction to currents North and South of it. Since the atmosphere is generally characterized as a fluid, we can imagine this as a water current which moves against the flow of the waters around it.

To explain why the hurricanes rotate in an opposite manner from each other from the equator we point to the the following videos, where friction in water creates oppositely rotating vortexes:

- Wooden Spoon Stroking Through Water Creates Counter-Rotating Vortexes (1m29s) - Dinner Plate Creates Counter-Rotating Vortexes in a Swimming Pool (2m20s)

The same general phenomena seen in the fluids of water in the above videos are occurring with the fluids of the air near the equator. When comparing the direction of the vortexes in the above video with the direction of the plate and spoon, to the direction of the Hurricanes and the direction of the Equatorial Counter Current, we find that, indeed, the directions match up. A "Coriolis Effect" is not needed to describe the rotational direction of these systems.

Counter Current Activity Correlated with Hurricane Development
The following is a study which associates Counter Current activity with the development of hurricanes.

Crossing the Equator
Coriolis Effect proponents further claim that hurricanes have never crossed over the equator into the opposing hemisphere. Although we have found articles of instances where storms have crossed, we accept the rarity and point out the following:

- At the equator exists a strong and permanent westerly-flowing current called the Equatorial Counter Current, which is bordered to the North and South by easterly flowing currents called the Northern and Southern Equatorial currents. Such a hurricane would need to defeat these currents in order to make it across.

- Hurricanes are created by these topical wind currents, and are sent spiraling Northward or Southward away from the tropical regions of the equator to cause havoc towards temperate regions of the North or South.

- Hurricanes have relatively short lives of an average of about 9 days.

The above points make it unreasonable for a hurricane to return to its origin and cross the equator to the other side.

=Addendum=

We suspect that if all of the the world's wind patterns, wind systems, and wind currents of the earth were traveling in a reverse manner to which they travel, Coriolis Effect proponents would instead be championing the Prevailing Winds and Trade Winds as proof of the Coriolis Effect and the rotation of the earth, while they ignore the hurricanes.
