Variation april 2010.
====================================================================
A case of tide variation would have taken place in Venice, starting on april 5th, 2010, because of the sun wind condition.

Legend of the tidal wave graphs.
On the numbers of the tidal waves.
Beginning of the effect of the perturbation.
Phase: last quarter moon, declination south 22°. The odd number wave #13, generated late, had to merge with the even number wave #14, usually in advance.
However, the advance of the wave #14 was compensated by the delay due to the sun wind perturbation, in agreement with the theory here presented.
Consequentely, by exception, the two waves do not merge.
The tidal waves #15 and 16.
The tidal wave #15 (odd number wave, thus late because of the Moon position) and the wave #16 (even number wave, in advance) merge into one. They are both late with respect to the times forecasted, because of the solar wind.
Within the components of the two waves, it should be pointed out their displacements ahead (compare the two outlines, the one as forecasted, the other as recorded).
Most part of the effect of the perturbation seems to have come to an end between the wave 16 and the wave 17. The outline of the wave group 17+18 becomes regular.
