Earth’s rotation is expected to accelerate in July and August, resulting in low days. In particular, on 9 July, July 22, and 5 August, the shortest day is predicted, as reported by timeanddate.com.
The decrease in the length of the day will be very short, measured in milliseconds. For example, on August 5, an average is expected to reduce about 1.51 milliseconds.
The Earth revolves 365 times on its axis, determining the number of days in a year. However, this has not always been the case, various calculations indicate that the orbital period of the Earth in the past varies from about 490 to 372 days, stated in the report.
Why will the Earth grow rapidly?
There are many factors that can be held responsible for the Earth’s rapid movement. According to scientists, the core of the Earth is affecting rotation. Relating of mass can also affect the process due to melting the glaciers.
Another factor that may possibly affect the rotation of the Earth is El Nino and La Nina, which affects global temperature. The moon can also be a factor. According to Timeanddate.com, the moon will be the lowest of day length (Lod) when the moon will be near its maximum distance from the equator on three possible dates in 2025.
What do experts say?
Judah Levin, a physicist at the Time and Frequency Division of the National Institute of Standards and Technology, shared with the Discover magazine in 2021, “Lap second was not predicted to lack the need for leap seconds.”
“The perception, in fact, that the Earth will continue at a slow pace and jump of seconds, and therefore this effect, this result, is very surprising,” Lavin said.
Rapid rotation may require changes in global timekeeping, possibly as a result of a leap of another in 2029.
Lyonid Zotov, a senior researcher at Moscow State University, “did not expect this to anyone.” “The cause of this acceleration has not been explained. Most scientists believe that it is something inside the Earth. The ocean and atmospheric models do not interpret this huge acceleration,” Zotov said.
