Arctic cold getting chewed by hungry sharks


The Arctic cold is still very strong for this time of the year.  Lots of black spots.  But the sharks are in a feeding frenzy.

The tropical plumes are getting up there and chewing away with heat energy.  The Atlantic belt is much stronger than the Pacific.  I finally figured out a good mechanism for an ice age cycle.  The Pacific current just stops.  Again we might expect it to start up again in 20 years.  If both oceans stop then this could be a big cycle. 

The Arctic ice volume curves is finally leveling off.  Yeah!  But I still expect a cold April, if measured in degree days, and not 'one day wonders'.

Hey Geofish:
this news caught my eye and I instantly thought you must see it!


"A severe thunderstorm cloud that formed over the Pacific Ocean in 2018 reached the coldest temperatures ever recorded, according to a new study.

The very top of the storm cloud reached a bone-chilling minus 167.8 degrees Fahrenheit (minus 111 degrees Celsius), colder than any storm cloud measured before. Thunderstorms and tropical cyclones, a circular low-pressure storm, can reach very high altitudes — up to 11 miles (18 kilometers) from the ground — where the air is much cooler, according to a statement from the U.K.'s National Center for Earth Observation.

But this new temperature is on another level. The top of the storm cloud was about 86 F (30 C) colder than typical storm clouds, according to the statement. The beast of a storm loomed about 249 miles (400 km) south of Nauru in the Southwest Pacific on Dec. 29, 2018, and its clouds' temperature was picked up by an infrared sensor aboard the U.S.'s NOAA-20 satellite orbiting the planet."

"But this storm was particularly extreme. "This storm achieved an unprecedented temperature that pushes the limits of what current satellite sensors are capable of measuring," Proud said in the statement. "We found that these really cold temperatures seem to be becoming more common."

In the last three years, scientists have logged the same number of extremely cold temperatures in clouds as they did in the 13 years before that, he added. "This is important, as thunderstorms with colder clouds tend to be more extreme, and more hazardous to people on the ground due to hail, lightning and wind."

This particular storm may have been energized by a combination of very warm water in the region and eastward-moving wind, according to the BBC. However, it's not clear why these colder temperatures in storm clouds are becoming more common. "

Okay I simply had to leave more here for you!

I have no idea. I'm still struggling with exactly how the tropical belt works.
