[Mpls] Re: 3rd Ward Primary - tidal waves

[Tim Bonham]

Sorry, Dennis, but I believe you're thinking of a tsunami wave.  Tidal waves are caused, oddly enough, by tides!   And it doesn't gain energy as it travels -- it loses energy.  But the remaining energy is compressed by shallower water and narrower harbor or river mouth openings, and thus forms a higher wave at landfall. 

I hope your candidate's knowledge of the ward is more accurate than your knowledge of oceanography. 

Tim Bonham, Ward 12, Standish-Ericsson

A good analogy would be a small seismic tremor out in the middle of the ocean hardly causes a ripple in the water - at first.  On its travels towards landfall the small ripple gains energy and momentum.  Upon arrival at landfall, the small ripple becomes a tidal wave.
