We’ve all witnessed at least once, on a very hot summer day, storm clouds gathered above us.

All of us on a very hot summer day storm we have witnessed the clouds gathering above us at least once. Here is a similar tropical storm system, the lowest temperature value recorded in the world may have been obtained.

The research on the system recorded just south of Ecuador in 2018 has just been published.

According to this Pacific OceanThe temperature value was measured as -111 degrees at the top of this tropical storm that occurred in the west of the city. This value is considered to be a record level.

This record observation on December 29, 2018 was made by the United States’ Noaa-20 satellite.

To explain in meteorological terms; As a very strong stream of air reaches the lowest layer of the atmosphere (troposphere), it generally flattens and takes an anvil-like shape.

But when the storm is very strong, the upward air flow can cross the troposphere and reach the next layer, the stratosphere. In the incident in 2018, the top of the cloud was 20.5 kilometers.

Speaking to the BBC, Simon Proud from Oxford University states that this situation is called the “overshooting ball”, and that the cloud’s peak cools 7 degrees per kilometer after passing the Tropopause layer.

Proud noted that the cloud that exceeded the Tropopause in the 2018 sample was 13 – 14 degrees colder.

Meteorologists from the University of Wisconsin-Madison, who published the research on the observation, consider that some additional factors contributed to this unusual situation.

‘Luckily this storm happened in the middle of nowhere’

Experts point out that for one reason, the ocean water in the area where the storm occurred is very hot. In addition, they say, a weather phenomenon called the Madden-Julian Oscillation also contributed.

The Madden-Julian Oscillation is tested for regional winds heading east, affecting wet and dry weather.

This observation also highlights the increase in the number of such super cold storms.

It has been observed that the number of similar storms in the last three years is equal to the 13 years before it. Considering that cold weather storms create more danger, this observation becomes important.

“Luckily this storm happened in the middle of nowhere,” says Simon Proud of the University of Oxford, pointing to the danger that may arise.
