Scientists have found out that cloudy weather means a warm wave in the Arctic region. This may seem paradoxical but it is true.

Clouds may mean that a warm wave is about to strike the Arctic region. This of course acts like too much of an already troubling problem which happens to be global warming. Researchers at NOAA found this strange occurrence and studied it in depth.

"As the Arctic atmosphere warms and moistens, it becomes a better insulator. While we expected this to reduce the influence from clouds, which provide additional insulation, we find that clouds forming in the Arctic in these conditions appear to further warm the surface, especially in the fall and winter," said Christopher Cox, lead author of the new paper published today in Nature Communications.

When the Arctic climate gathers heat and humidity it acts rather like an insulator of sorts. And the clouds have a further warming effect which was worrisome indeed.   

Especially in the Autumn and Winter season, the surface temperatures rise. Cloudy weather sure does play a complex part in the climate change story.

They may cool the earth by reflecting the sun’s light and they may also act as an insulation device and keep the earth warm. It is a dual policy they play in the atmospheric conditions. The effect of the clouds cannot be overstated.

In the frigid North, the clouds are even more of a mysterious phenomenon. The complicated interplay of forces between temperature levels, humid conditions and the state of the clouds lend the word “chaos theory” its full meaning. 

In the Arctic, the air is colder and much more drier than in the southern regions. Several measurements were taken by the experts. Meteorological reports were also examined in depth.

The downwelling infrared cloud radiative effect was also noted down. It was seen that as the atmosphere became warmer and more moist it caused insulation. While normally adding clouds to the equation didn’t spell much of a difference, in the Arctic it did have a deep impact.

It was as if a person has a warm blanket on his body during winter and then he adds another blanket on top of it. This may not cause much additional warmth but in case of the Arctic Paradox it definitely did with the additional clouds causing much greater concentration of heat.

The clouds preserve their properties and warm the surface one way or another. And the changes in temperature and humidity play a key role in these curious thermal circumstances.

Due to the fact that there is very little sunlight in the North, the clouds prove to be insulating agents instead of lending any cool shade of any kind. Several computer simulations of the weather were also generated and the experts learnt a lot about the Arctic warm waves due to cloudy conditions along the way.
