- The wildfires are currently raging in the United States and Canada are so intense that they have created ‘pyrocumulonimbus’ clouds.
- They have the potential to spit out thunder and spark more fires.
- Before 2023, 102 pyrocumulonimbus were recorded globally in a single year on average - 50 of them were seen in Canada.
- They occur only when there is an extremely hot wildfire.
- Volcanic eruptions can also lead to the formation of pyrocumulonimbus clouds.
- For instance, these clouds were formed during the Australian bushfires of 2019-2020 when temperatures crossed 800 degrees Celsius.
- These clouds can reach heights of 50,000 feet and generate their own systems of thunderstorms.
- These clouds can produce lighting, but do not generate much rain.
- As a result, they can spark new wildfires many kilometres away from the main blaze.
