What's that cloud?

 

 

 

Of all weather phenomena, clouds are among the most fascinating. From the silky, high-altitude cirrus to the towering, threatening mass of storm-bearing cumulonimbus, clouds are as varied as the weather itself.


Apart from their beauty and interest, clouds can provide a useful indication of what weather conditions may be on the way. By knowing the ten main cloud classifications, you can get a real sense of what’s happening in the atmosphere.

Cloud formation

Clouds have their origins in the water that covers 70 per cent of the Earth's surface. Millions of tons of water evaporates into the air daily from oceans, lakes and rivers, and by transpiration from trees, crops and other plant life.

As this moist air

On 9 February, R/V Kronprins Haakon departs on a winter process cruise to the Barents Sea to track and measure important processes taking place in the ocean during wintertime. This cruise is led by UNIS professor Frank Nilsen and part of the Nansen Legacy project – Norway’s biggest research project to date.

Arctic seas have historically been little accessible during winter, but it is during this time of the year that important atmosphere-ocean-processes are taking place. The heat fluxes between the sea and the atmosphere are greatest during winter. These processes are crucial for the Barents Sea for the rest of the year and affects, among others, how

We already get energy from the sun and the wind, but nobody has successfully tamed the power of the sea – yet. 

Now Danish researchers are making a new attempt using a two-legged wave power plant called Weptos.

A prototype has been tested in a new wave tank in Spain – a test that the developers say was “exceedingly promising”. They believe Weptos can be the key to channelling energy from the sea

"Are hydro-connected floating solar power plants part of the answer to both the integration of more variable renewable energy and the modernization of old renewable assets? Most probably", according to Stanislas Merlet and Bjørn Thorud. (Photo: PowerUp / Shutterstock / NTB)

Floating solar power connected to hydropower might be the future for renewable energy

OPINION: Hydropower plants need an upgrade. And we need to use more renewable energy sources. The solution? Floating solar power connected to existing hydropower plants.
