Sea ice appeared in northern Greece as sub-zero Celsius temperatures followed the blizzard
Sea froze in Greece in a once-in-a-lifetime phenomenon that appeared on Tuesday at the village Sagiada in Thesprotia, Epirus. Sea ice, usually found in more northern and polar oceans, appeared in Greece as the country was hit with sub-zero temperatures.

Videos uploaded on social media show a thin layer of ice on the surface of the sea, which is unique in Greece. Sea Ice usually occurs in northern Atlantic, Arctic and Antarctic, not Greece.

Sea ice is simply frozen salt water. It forms, grows, and melts in the ocean. In contrast, icebergs, glaciers, ice sheets, and ice shelves all originate on land. Sea ice occurs in both the Arctic and Antarctic as well as the northern Atlantic.

Scientists explain mysterious finger-like features in solar flares

Astronomers have presented a new explanation for the mysterious downward-moving dark voids seen in some solar flares.

Cambridge, MA -- In January 1999, scientists observed mysterious motions within a solar flare.

Unlike typical flares that showed bright energy erupting outwards from the Sun, this solar flare also displayed a downward flow of motion, as if material was falling back towards the Sun. Described as "downward-moving dark voids," astronomers wondered what exactly they were seeing.

Now, in a study published today in Nature Astronomy, astronomers at the Center for Astrophysics | Harvard & Smithsonian (CfA) offer a new explanation for the poorly understood downflows, now referred to as supra-arcade downflows (SADs) by the scientific community.

"We wanted to know how these structures occur," says lead author and CfA astronomer Chengcai Shen, who describes the structures as "dark finger-like features." "What's driving them and are they truly tied to magnetic reconnection?"

Children build a snowman in front of the Dome of the Rock, in Jerusalem’s Old City, January 27, 2022.
Snow carpeted Jerusalem and the eastern Mediterranean Thursday as a rare storm turned the holy city into a winter wonderland but brought misery to the region's Syrian refugees.

The cold snap, which has already caused major disruption in Athens and Istanbul, saw heavy snowfall in areas better known for their summer heat.

In the alleyways of Jerusalem's walled Old City, children pelted each other with slushy snowballs after the first flakes fell late on Wednesday.

By morning, snow crowned the golden-tipped Dome of the Rock in the Al-Aqsa mosque compound, Islam's third holiest site and carpeted the esplanade in front of the Western Wall, the holiest site where Jews can pray.

Israel's meteorological service reported that between 15 and 25 centimetres of snow had fallen overnight.

Cold front brings snowfall to the Canary Islands

With heavy rainfall throughout the night, including on much of the north and inland areas of Gran Canaria, a cold front wet weather system known as a "gota fria" (cold drop) or DANA (Depresión Aislada a Niveles Altas - high level isolated depression) has deposited a blanket of snow, this Wednesday, at the summits of of Tenerife and La Palma islands, with meteorologists warning it could also do so on the island of Gran Canaria, ahead of a return to Calima desert sands arriving from the east, expected by the weekend.

Southern resort areas are most likely to escape the worst of it, however most places are likely to see cloudy wet weather over the coming days.

Southern Ocean storms cause outgassing of carbon dioxide

Researchers have examined the inaccessible waters around Antarctica using unique robot technology, and find that ocean storms in the region lead to outgassing of carbon dioxide into the atmosphere.
Storms over the waters around Antarctica drive an outgassing of carbon dioxide into the atmosphere, according to a new international study with researchers from the University of Gothenburg. The research group used advanced ocean robots for the study, which provides a better understanding of climate change and can lead to better global climate models.

The world's southernmost ocean, the Southern Ocean that surrounds Antarctica, plays an important role in the global climate because its waters contain large amounts of carbon dioxide. A new international study, in which researchers from the University of Gothenburg participated, has examined the complex processes driving air-sea fluxes of gasses, such as carbon dioxide.

Storms bring carbon dioxide-rich waters to the surface

The research group is now delivering new findings that shed light on the area's important role in climate change.

"We show how the intense storms that often occur in the region increase ocean mixing and bring carbon dioxide-rich waters from the deep to the surface. This drives an outgassing of carbon dioxide from the ocean to the atmosphere. There has been a lack of knowledge about these complex processes, so the study is an important key to understanding the Southern Ocean's significance for the climate and the global carbon budget", says Sebastiaan Swart, professor of oceanography at the University of Gothenburg and co-author of the study.

Sharon Springs, Kansas
What's left of the snowstorm that dumped more than two feet in a couple far western Kansas counties began to taper off Tuesday night, but with cold temperatures forecast over the next few days, melting won't happen quickly.

While Interstate 70 reopened earlier Tuesday evening with the storm finally letting up, the impact on travel continued into late Tuesday night. Highways in southwest Kansas were also impacted by the snow. US-54 closed earlier Tuesday evening after a semi crash. For a few hours, this stranded some travelers in Pratt.

The city of Athens with the Parthenon temple atop the ancient Acropolis hill is covered with snow during a snowfall, on Monday, Jan. 24, 2022.The wave of bad weather hitting Greece is forecast to continue through Tuesday, and has seen snow falling even on some islands. Authorities have warned the public to avoid all but essential outdoor movement, and several major roads and highways are passable only with snow chains.
Athens, Greece — Heavy snowfall disrupted air and road traffic Monday in the Greek capital of Athens and neighboring Turkey's largest city of Istanbul, while most of Greece, including — unusually — several Aegean islands, and much of Turkey were blanketed by snow.

The storm, named in Greece Elpida, or "hope," snarled traffic in both Athens and Istanbul, a metropolis of 16 million people.

Flights in and out of Istanbul Airport were suspended until 4 a.m. Tuesday (0100 GMT). Authorities worked to clear runways and a road leading to the airport, where the roof of a facility used by Turkish Airlines' cargo department collapsed from the weight of snow. No one was hurt.

Authorities in Istanbul also suspended intercity bus services and temporarily blocked travel to the city from Turkey's Thrace region. People stranded on roads abandoned vehicles to walk home or crowded subway and other public transportation stations. Schools across Turkey are closed for a winter break, but universities halted classes for two days. Public offices and shopping malls closed early to ease rush-hour congestion.

Flurries were forecast to continue over the next few days in Istanbul. The Turkish city's Disaster Coordination Center AKOM said an Icelandic low-pressure system is behind the cold front and precipitation.

In Greece, authorities warned the public to limit outdoor movements to only essential ones on Monday and Tuesday, while schools in many areas were closed. Government spokesman Giannis Oikonomou said more than 46,000 school classes were being held online.
