At least once, on a hot summer day, we all witnessed storm clouds gathering over us. Here, in a similar tropical storm system, the lowest recorded heat value in the world may have been obtained.
A study on the system, which was registered in 2018 in southern Ecuador, has just been published.
Therefore, the temperature above this tropical storm in the western Pacific Ocean was measured at -111 degrees. This value is considered a record level.
This record was observed on December 29, 2018 by the US Noaa-20 satellite.
Explain from a meteorological point of view; When a very strong air current reaches the lowest layer of the atmosphere (the troposphere), it generally flattens out and takes on a similar shape.
However, when the storm is very strong, the upper air flow can pass through the troposphere and reach the next layer, the stratosphere. In the 2018 event, the peak of the cloud was 20.5 kilometers.
Speaking to the BBC, Simon Proud of Oxford University said the situation was called a “ball of overtaking” and that the cloud peak had cooled to 7 degrees per kilometer after passing through the Tropopoz layer.
Proud noted that in the 2018 sample, the cloud that surpasses Tropopoz is 13 to 14 degrees below zero.
Meteorologists at the University of Wisconsin-Madison, which published the study, believe that some additional factors are contributing to this unusual situation.
‘Fortunately this storm happened nowhere in the middle’
Experts suggest that for some reason the ocean water in the area where the storm occurred is very hot. In addition, a weather phenomenon called Madden-Julian Oscillation is said to help.
Madden-Julian Oscillation affects wet and dry weather for regional winds to the east.
This observation also emphasizes the increase in the number of such super cold storms.
The number of similar storms in the last three years was the same as in the previous 13 years. Given the fact that cold weather storms pose a greater threat, this observation is even more important.
“Fortunately, this storm happened in the middle of nowhere,” said Simon Proud of Oxford University, pointing to the danger.
