Tide clock This is often complicated because the lead or lag varies during the course of the lunar month, as the lunar and solar tides fall into and out of synchronization. The lunar tide and solar tide are synchronized (ebb and flow at the same time) near the full moon and the new moon.

Empty Cities of the Full Moon Empty Cities of the Full Moon Empty Cities of the Full Moon is a science fiction novel by Howard V. Hendrix first published in 2001. The novel revolves around the near extinction of humanity by an artificial prion originally designed to help the mentally ill but which becomes a shamanistic pandemic of madness, shape-shifting and death. There are 2 plots-lines which each follow the same set of characters before and after this near extinction. The title of the novel comes from both the correlation between the pandemic's symptoms and the full moon, and that the pandemic effectively emptied the cities.
