Deciphering the 'natural wind' mysteriously caused the researchers a headache

Since ancient times, people have felt the change of the air when natural disasters occur (eclipses, eclipses). But we have to wait until today to get an explanation thanks to modern weather forecasting technology.

Mysterious weather changes when eclipse

Eclipse.

After 301 years after the English astronomer, Edmund Halley , was a pioneer in observing eclipse . He noticed a strange weather change that coincided with the time of the natural occurrence. That's when an eclipse happens, the air will become unusually cold and wet , a shuddering and frightening feeling like watching horror movies.

In 1901, H. Helm Clayton also predicted that the wind would change direction when there was an eclipse.

To find the answer to this relationship is not simple. Scientists spend a lot of time with the help of thousands of volunteers to solve this mystery.

Large-scale experiment with modern equipment

Temperature changes when eclipse.

Meteorologists from the British University of Reading, Giles Harrison and 4500 volunteers conducted the National Eclipse Weather Experiment to measure the meteorological effects of eclipses.

When the solar eclipse occurred, combining observations and reading weather parameters at the weather stations on the ground, as well as the weather sensor system, the team confirmed the air became colder when available. eclipse, wind blowing slower and changing direction.

Atmospheric physicist Giles Harrison said:

" When the Sun disappears after the Moon, an area of ​​the area is suddenly cold, like a sunset. That means warm air is suddenly stopped around this area, which is also the cause of temperature drop. and change the direction of the wind There are many theories given to explain the eclipse of the wind that happens every year, but we think this is the most convincing explanation . "

The mystery has been answered.

This strange weather phenomenon occurs strongly in the border area, where the border between morning and evening. When the solar eclipse occurs, the air will get cold from 1 to 4 degrees Celsius, the wind speed will also decrease by 7.4 km / h, the wind direction will also turn south about 20 degrees.

Gray and his colleague Harrison also stressed that it would take a long time to get concrete figures, although many theories were made because it was not as accurate as the current weather forecasting technologies. .

The study was published in the journal Philosophical Transactions of the Royal Society A.

Celestial reality is an astronomical event when a celestial body moves into the darkness of another celestial body. The two most known celestial phenomena are the lunar eclipse , when the Moon enters the shadow of the Earth and the eclipse, when the Earth enters the darkness of the Moon.
