According to a recent study, a thunderstorm cloud formed over the Pacific Ocean in 2018 has reached the coldest temperature ever recorded.

The peak of this thunderstorm cloud was “bone-cold” to minus 167.8 degrees F (minus 111 degrees C), colder than any previously measured thunderstorm cloud.

Essentially, thunderstorms and tropical depressions can reach very high altitudes – up to 11 miles (18 km) from the ground – where the air is extremely cold, according to the National Center for Earth Observations. University of Oxford (UK).

However, the peak of this newly discovered thunderstorm cloud is approximately 86 degrees F (30 degrees C) colder than typical thunderstorm clouds. Previously, this bizarre thunderstorm cloud was discovered on December 29, 2018, as it was circulating in the southern region of the Nauru island nation, in the southwest Pacific region. The temperature of the thundercloud is determined by the infrared sensor equipped on the US satellite NOAA-20.

According to LiveScience, storms often spread in an anvil-like shape as they reach the top of the troposphere, the lowest layer of Earth’s atmosphere. But if a hurricane has a lot of energy, it will launch into the next atmosphere – the stratosphere. This phenomenon, known as “overlying clouds”, pushes storm clouds to very high altitudes where the air is very cold.

According to Simon Proud, an expert at the UK National Earth Observation Center, the phenomenon of ‘cloud over floors’ is relatively common.Usually, the temperature of thunderstorms will drop by 7 degrees Celsius each time it rises by 1. km in the stratosphere.

However, the storm discovered in December 2018 was particularly extreme.

“This storm reached unprecedented temperatures, pushing the limits of what current satellite sensors can measure. We find that these really cold temperatures seem to be becoming commonplace. more, “warns Simon Proud.

Notably, the number of thunderstorms with super-cold temperatures recorded in the past 3 years is as much as 13 years ago.

“This is important, because thunderstorms with colder clouds tend to be more extreme and more dangerous for people on the ground due to hail, lightning, and wind.”

The storm appeared near the island nation of Nauru on December 29, 2018, captured in infrared by an orbiting satellite. The cold clouds are purple and the warm waters of the Pacific Ocean are orange.

According to the BBC, storms in the Pacific in 2018 could be powered by a combination of warm sea water in the region and winds moving eastward. Meteorologists still don’t know why super-cold thunderclouds are gaining popularity, however.

We now need to understand whether this increase is due to the sea of ​​climate change, or if this is merely a ‘perfect storm’ generated by current weather conditions, which are constantly producing waves. extreme thunderstorms over the past few years “.
