Parts of Brisbane have been inundated with water as an unusually high tide hit the city’s low-lying areas, including the Moreton Bay Island…..
The tide is due to the first full moon of the year and the extra pull it has on the world’s water.
The Bureau of Meteorology’s tide predictions for Brisbane had Wednesday’s high tide hitting 2.75 metres, which was the highest tide prediction for 2018.
The king tides occur when the Earth, Moon and Sun are aligned at perigee and perihelion, resulting in the largest tidal range seen over the course of a year. So, tides are enhanced when the Earth is closest to the Sun around January 2 of each year. They are reduced when it is furthest from the Sun, around July https://en.wikipedia.org/wiki/King_tide
Tides are the movement of water across Earth’s surface caused by the combined effects of the gravitational forces exerted by the Moon, Sun, and the rotation of Earth which manifest in the local rise and fall of sea levels. Tides are driven by the relative positions of the Earth, Sun, Moon, land formations, and relative location on Earth. In the lunar month, the highest tides occur roughly every 14 days, at the new and full moons, when the gravitational pull of the Moon and the Sun are in alignment. These highest tides in the lunar cycle are called spring tides
The highest tides in the world can be found in Canada at the Bay of Fundy, which separates New Brunswick from Nova Scotia. At some times of the year the difference between high and low tide in this Bay is 16.3 meters , taller than a three-story building.
