I did some more research on it, but found zilch accept the above link. But in my effort I also found some useful info, such as the angular velocity, tangetial velocity, the conservation of angular monmetum and the coriolis effect, etc. I never knew the earth moved at 7.29 x 10 to the negative 5th power and one radian equaled 57.2958. Very interesting. I have come up with another hypothesis, what if the forces and effects metioned above indirectly effect the pressure drop at the surface, making it easier to fall 24 mb in 24 hours at 60 then opposed to the mid-latitudes. Some forces are much greater at 60 then opposed to 45 degrees. Just a suggestion.
