“In 2019, the conditions lined up with the snowpack, wind, moisture blowing off the mountain and the light filtering through the clouds that creates a perfect orange.”

A warmer atmosphere holds more water, so as the planet heats up, we can expect more extreme rain “whenever the conditions are right to squeeze that moisture out,” he said.

Warmer air can hold more moisture, and he says there was a "strong link" between these sea temperatures and the 2019 extreme rains over East Africa.

This is when high pressure traps an area of moisture close to the surface of the Earth.

The moisture forms low cloud, mist and fog, which then cannot lift and clear as the winds are so light and the sunshine at this time of year is so weak.
