It has come to my attention that some Spherical Earther's say that the Coriolis Effect is a major, while other say that it is minor.
I would like for the Spherical Earther's to debate this and come to a conclusion if it is a major of a minor, on a Global scale.
Please tell us
You decide!
Firstly the effect on hurricanes, typhoons and cyclones.
Why is there a clear band that cyclones and hurricanes rarely cross?
I would say that something that causes
hurricanes, typhoons and cyclones to rotate in a counter-clockwise in the Northern Hemisphere and
cyclones to rotate in a clockwise in the Southern Hemisphere,
is a rather major effect on a
Global scale and if you've been through a cyclone or hurricane, I'm sure you'd agree.
Even when it comes to the ordinary weather patterns of
Highs and
Lows, something causes the
four distinct situations observed for High and Low Pressure Weather systems,
These include Hurricanes, Typhoons and Cyclones, in the Northern and Southern Hemispheres.
| | Northern Hemisphere | | Southern Hemisphere |
Highs | | Clockwise | | Anti-clockwise |
Lows | | Anti-clockwise | | Clockwise |
Just look at weather maps that show highs, lows and wind directions to verify this for yourself.
Explain that without the Coriolis effect - looks a pretty major
Global effect to me!
But, if you want big Coriolis, here's big Coriolis and long-range artillery, and the
Coriolis Effect, try the "Paris Gun" used by Germany in WW I. It's at ranges like thus where the Coriolis and Eötvös effects become essential.
Have a look at:
In June 2002 issue of Military Heritage there is an article on Paris gun and a good part of it is about calculations that needed to be done in order to ensure accuracy. So,the Germans digged out the works of one Gustave Gaspard Coriolis (1792-1843),who in 1835 published his Sur les Equations du Mouvement Relatif des Systemes de Corps ("On the equations of Relative Motion of System of Bodies"),in which he stated that ,due to spherical nature of the Earth and it's rotation, a moving object on a north-south vector would be affected by the relative rotational speeds of launch and impact points. Earlier German use of long-range guns (firing from Lugenboom on Dunkirk), didn't have to take into account Coriolis Effect, because the firing site and target were on an east-west axis. Obscure mathematician von Eberhardt, at the time working for Krupp, understood the problems of firing on the north-south axis, so he based his research on Coriolis' works and made calculations accordingly.
Being advised on the site of the gun (Crepy-an-Laonnois), he estimated rotational speed of Paris at 567 mph on the 49th parallel and that of Laon at 555.55mph on the 48th parallel.So, an adjustment of 11.58 mph had to be provided for the laying of the gun. Also, he calculated the estimated flight time at 176 seconds and this called for easterly correction of 0.5659 miles to compensate for differing rotational speeds of gun and target.
I am not too keen on math 
but this article really captured me, showing how much hard work (apart from technical aspects) was needed just to fire this gun. And all this was done without computer...

Yes, I know long range artillery relies of spotters to correct the azimuth and elevation angles, but to get over half a mile out is a bit much!
But when it comes to
water-down-the-drain, aircraft or cars there to many other effects for the very small Coriolis effect to be even measurable.
So, is the Coriolis efect major or minor on a
Global scale?
PS I know one very weak cyclone did start rotating counter-clockwise near India, then drifted around,
finally crossed the equator and
promptly died!
