‘Snowmania’ in Zambia

h/t Argiris Diamantis

THE Zambia Meteorological Department says the recent hailstorm in some parts of Lusaka was due to a cool vertical atmosphere that did not support its melting into rain.
In a statement following Sunday’s heavy hailstorm, senior meteorological officer Victor Bupe said a cold front over the southeast coast of South Africa tilted towards the north, thereby interacting with the Congo air mass over the eastern half of Zambia.

“The fall of ice found a vertical atmosphere that could not support ice melting into rain,” said Bupe.

‘Snowmania’ hits Lusaka after rare Winter Rains

Images showing some excited residents of Lusaka posing in what appears to be piles of Snow have flooded several social media platforms.

On Sunday evening, Lusaka and surrounding areas recorded heavy rains which turned a hailstorm, a rare occurrence in May.

The hailstorm saw piles of hailstones forming in several parts of the city and covered some busy streets to the amusement of some residents.

In some parts of Makeni area, residents from Children and elderly ones ran out in the chilly weather and posed for photos playing with the hailstones.

Others even started creating structures such as Snowman while others boasted that Lusaka has now started experiencing snow just like other cities in Europe and the Americas.

The hailstorm has now brought it with it low temperatures averaging 12 degrees Celsius from Monday.

The Meteorological Department last month warned that the coming Winter season will be one of the coldest ever recorded.

Meteorologists explain The Scream

Was Edvard Munch seized by panic at the sight of “screaming clouds?”

I was walking along the street with two friends – and the sun set. Suddenly, the sky turned blood-red and I felt a shiver of sadness. A feeling of oppressive pain in my breast.“ This is how the Norwegian painter Edvard Munch described the state of feeling which he translated into his famous painting The Scream.

“I stopped in my tracks, leaned against a fence, because I felt tired to death. Above the blue-black fjord and the city, blood lay stretched out in tongues of fire. My friends proceeded ahead – and I found myself left behind, trembling with fear. And I felt that a mighty, endless scream was tearing through all of nature.”

Had Munch at that time in Oslo turned his insides out in his famous painting, as art theoreticians believe? Venting a fear of life, or of death? Was The Scream an image of the state of his soul? Or was there an external trigger for his work?

Indeed, there could have been such, meteorologists have been guessing for some time. Munch‘s Scream may have been inspired by the aspect of the sky, a gigantic cloud of ashes having spewed forth from the Krakatoa volcano in Indosia and having spread around the world in 1883, giving the sunlight a reddish cast for two years, or more. It is quite possible therefore that the painter may have seen this “blood in tongues of fire” appearing in the sky as a real phenomenon.

However, the eruption took place nine years before Munch is said to have painted The Scream. And something else did not fit quite right with a volcano-colored sky: Munch painted dramatic, red waves – but particles of ash at the borders with space are glowing as a solid, red film.

Meteorologists are now proposing a new explanation: it had been a special, rare kind of cloud which had colored the sky of Oslo in this way and produced such a deep impression on Munch. “Mother-of-pearl” clouds, which appear rarely and only in winter at high latitudes, at heights of 20km, resemble the sky-waves represented by Munch, according to a group of Norwegian scientists.

Munch’s panic can be best explained by mother-of-pearl clouds, Helene Muri from the University of Oslo explained at the annual conference of the European Geosciences Union (EGU) in Vienna, where she presented the results reached by a scientific team gathered around her colleague, Svein Fikke.

The Russians Hacked the US Winter Weather ;)

From Dr Roy Spencer:

Now that winter has officially ended, I thought it would be useful to address the central role that Russia played in ending California’s drought, as well as in the unusually warm conditions over the eastern U.S. this past winter.
First, let’s address the record California rains and mountain snowpack. While such a wet winter usually requires a strong El Nino, we had just the opposite — a weak La Nina.

So, what happened?

California: The “Atmospheric River” Doesn’t Explain It

Blaming the wet winter in California on the “atmospheric river” effect is, in my professional opinion, rather lame. It’s like blaming a flash flood on “too much water”. Well, duh.

So, what caused the atmospheric river?

A persistent series of extratropical storms (low pressure systems) coming into California.

But what caused the storms?

An enhanced temperature contrast between the tropics and mid-latitudes, always required for the formation of such low pressure systems.

But what caused the enhanced temperature contrast?

It wasn’t El Nino, the usual culprit in stormy California winters, because we had the opposite — La Nina.

It was because our winter was hacked by the Russians

It all started back in October, 2016. (Before the election! A coincidence? I think not.)

October experienced an unusually rapid buildup of the cold season air mass in Siberia, as seen in this temperature departure-from-normal map (all maps courtesy of Weatherbell.com):
