Moon Wobble:
Sometimes, the moon seems to move in mysterious ways. It is mostly circles and ovals. But there is also something else a so-called wobble animating those rotations and revolutions. According to a recent study, the phenomenon is expected to lead to more flooding here on Earth in the middle of the next decade.
- The moon wobble is nothing but a regular swaying in the moon’s orbit.
- It was first documented way back in 1728.
- This wobble takes over an 18.6-year period to complete, and continues in a cyclic fashion.
- The moon wobble impacts the gravitational pull of the moon, and therefore, indirectly influences the ebb and flow of tides here on the Earth.
- In fact, as per the NASA study, each wobble cycle has the power to amplify and suppress the tides on Earth.
- One half of the 18.6-year cycle suppresses the tides, which means that the high tides get lower, while the low tides get higher than normal.
- Once this cycle completes, the situation flipsin the subsequent cycle, the tides are amplified, with high tides getting higher and low tides, lower!
- The lunar cycle is expected to shift again by mid-2030, and in the coming phase, the tides will amplify once again.
- The upcoming changes in the lunar cycle will pose a serious threat, as the amplified high tides coupled with the rising sea levels will make the risk of flooding far greater across all coastal regions of the globe.
- The study predicts that the high tide-associated floods also known as nuisance floods or sunny day floods may occur in clusters that could last for months or even for longer periods!
