Arctic sea ice has been declining rapidly over the past few decades, and changes in Arctic sea ice can have significant effects on global weather and climate through interactions with the atmosphere and oceans. In addition, the Arctic shipping routes are a shortcut to connect the major countries of the Northern Hemisphere. The Arctic is also rich in natural and biological resources. The simulation of the Arctic sea ice could provide valuable information for Arctic shipping as well as for climate studies. Therefore, there is an urgent need to assess the ability to simulate the Arctic sea ice and diagnose the causes of simulation errors.

To address the problem of identifying sources of error, Prof. Fei Zheng and his team from the Institute of Atmospheric Physics of the Chinese Academy of Sciences evaluated the sea ice simulations of the Arctic regional ocean-ice coupling configuration from the Massachusetts Institute of Technology General Circulation Model (MITgcm).

“We evaluated the model’s performance in the arctic cold season (March) and warm season (September) and found that the model performance was different in the two months,” says Zheng. “Due to the uncertainty of the model, the insufficient response of the model to the signal from atmospheric forces and the insufficient response to the ocean boundary signal, there were disagreements between the simulations and observations in both March and September.”

According to her article published in Advances in Atmospheric Sciences, the properties of seasonally varying sources of model error could be fully accounted for using an ensemble approach to achieve the goal of improving the simulation and prediction of Arctic sea ice in different seasons in future work.

Trump boasts of Covid’s response as December seems to be deadliest month but

President Donald Trump speaks in a video posted on Twitter on December 31, 2020.

The White House | Twitter

WASHINGTON – In the final days of 2020 there has been a surge in coronavirus deaths in the US, cases surge to staggering levels, hospitals strained, and much-needed vaccine rollouts lagging behind expectations.

December was America’s deadliest month during the pandemic. But President Donald Trump hardly said a word about the tragic toll of Covid-19.

Instead, the president spent the month pondering unsubstantiated allegations of a stolen election, delaying relief laws before they were signed, weighing cable newscasts, and beating members of his own party.

And on Thursday, the last day of the month and year, Trump tweeted a video boasting about his administration’s response to the pandemic.

In December, the country plunged into the toughest battle against Covid-19, even as vaccines ran out. The nation reported more than 6.1 million new infections and more than 74,140 deaths, according to Johns Hopkins University.

The latest totals make December the deadliest month of the Covid-19 pandemic in the United States, beating April when more than 60,738 Americans lost their lives to the coronavirus.

Since the coronavirus outbreak began, at least 342,414 Americans have died from the disease, which Trump has repeatedly pledged on 40 different occasions.

In a taped message released Thursday, Trump made the lion’s share of the loan for the unprecedented speed in the development of vaccines, which the stunt called a “medical miracle”.

“Thanks to Operation Warp Speed, we developed a vaccine in just nine months, we have already launched a nationwide vaccination program and we are sending the vaccine all over the world. The world will benefit, we will benefit, and everyone is calling for it . ” Thank you, “said the President.

Trump also took a moment to praise his work on the economy, saying that his administration “built the greatest economy in the history of the world”.

“We’re now doing numbers like no one has seen before, including the highest stock market in the history of the world,” Trump said, adding “the best is yet to come” in his deregistration.

The White House did not immediately respond to a request for comment.

Tweets and golfing

Trump, who vacationed last week at his private club in Palm Beach, Florida, returned to the White House Thursday as lawmakers debated laws that would reduce Covid aid payments to $ 2,000 in the face of historic unemployment and business closings would increase.

The President himself pushed for these higher payments despite the fact that Senate Republican leader Mitch McConnell refused to hold a stand-alone vote on the bill providing for the higher payments, which were passed with the support of both parties in the House of Representatives.

While in Palm Beach, Trump spent several days playing golf on his for-profit golf course, sending 110 tweets, mostly focusing on false claims of a rigged presidential election and the upcoming Georgia Senate runoff.

Trump, despite a series of failed legal challenges, did not concede the election as Democrat Joe Biden, which will be inaugurated on Jan. 20. The president also went on Twitter for support for an upcoming rally in Georgia.

The president’s refusal to address other aspects of the looming public health disaster comes because the governors of Colorado and California are confirming a new and potentially contagious strain of Covid-19 in their states.

Hospital fights and vaccine stumble

Officials from the Centers for Disease Control and Prevention said earlier Wednesday that the new tribe could put pressure on the country’s hospitals, which are already overwhelmed with Covid-19 patients.

Coast-to-coast hospitals are already running out of available intensive care units and standard beds to accommodate the surge in patients, data from the Department of Health and Human Services shows.

Earlier this month, the United States began rolling out vaccines to fight the disease. But health officials have warned that a vaccine will not immediately rid the country of the outbreak.

The nation’s health officials previously stated their goal was to vaccinate at least 20 million Americans with their first shots before the end of the year. You will clearly miss this goal.

As of Monday morning, more than 11.4 million doses of Pfizer and Moderna two-dose vaccines had been distributed across the country. According to the Centers for Disease Control and Prevention, approximately 2.1 million of these shots were given to humans.

Trump, who was criticized for missing the vaccine target, blamed the unorganized introduction of vaccines for the states.

“The federal government has distributed the vaccines to the federal states,” said the president in a tweet. “Now it is up to the states to manage. Move on!”

“Completely different Form of Problem”: How the Peach Bowl Planning Made Georgia versus Cincinnati potential

The Chick-Fil-A Peach Bowl – one of six New Year’s Day bowls – will come into focus on Jan. 1 with a matchup between Georgia and Cincinnati.

It’s the third time an undefeated group of 5 teams has played in the bowl in seven years – and the Bearcats will try to maintain their undefeated season against the Bulldogs in the state. It should be an exciting matchup generating storylines about the G5’s role in the college football playoff structure.

Behind the scenes, however, there’s a different way of preparing for game day that started with the disappointment caused by the ongoing COVID-19 pandemic in the United States. Gary Stokan, CEO of Peach Bowl, recalls this disappointment after the cancellation of all three Chick-Fil-A kickoff games that were due to take place at Mercedes-Benz Stadium in Atlanta from September 5th to 12th.

A blockbuster weekend of matchups between West Virginia and Florida (September 5), Georgia and Virginia (September 7), and North Carolina and Auburn (September 12) has been wiped out. The goal changed from “the biggest opening weekend” to the “safest chick-fil-a peach bowl”.

Stokan likes to use one of his favorite phrases: “An attitude of gratitude.”

“In some ways, it was good that we did a lot of homework and had a lot of best practices for the bowl game,” Stokan told Sporting News. “But it was very disappointing because we put so much work and effort with these six teams only to find out we had to cancel the games.”

A total of 18 bowl games were canceled this year. the newest Texas Bowl matchup between Arkansas and TCU. The Peach Bowl will remain open for Friday and will serve as the basis for the two College Football Playoff semifinals.

Stokan said weekly planning meetings with the fellow Six Year’s Day Six CEOs and the college football playoff committee made this possible. Stokan also followed events with Atlanta United in the MLS and the Atlanta Falcons in the NFL at Mercedes-Benz Stadium.

The stadium seats 75,000, but for the Peach Bowl it will have a 25 percent capacity between 16,000 and 17,000 fans. Stokan went through the logs showing pods of two and four.

Masks are required – and are available at the gates. Only necessary personnel are allowed on the field. Presentations on the field are not allowed and there are no bands, cheerleaders or mascots.

Of course, there are also strict detailed COVID-19 test protocols.

“We’re going to test all of the workers, all of our employees, all of the people who come on the field, all of the ESPN people and all of the officials,” he said. “That was a different challenge than ever before.”

Stokan, a former North Carolina state assistant basketball coach, also created a depth map for Peach Bowl staff and volunteers to shift responsibilities on COVID-19 coaches.

“You always have to have a next-person mentality and prepare this second-team man if the first-team person fails,” he said. “We had to create a succession plan for our employees and with our volunteers in case someone had to be quarantined during the day or during the week. This is unique. There is no doubt about it.”

In that regard, Stokan appreciates the schedule that the Power 5 conferences were able to negotiate during the season. The SEC had only canceled two games in its 2020 season.

“I really admire it can’t be said enough what the medics, coaches, the ADs, the staff of the players, the coaches really did to have a game,” said Stokan. “It’s remarkable to me that we had a college football season.”

Stokan said the downside is the teams aren’t there all week, and that doesn’t just apply to the Battle for Bowl Week activities. Atlanta Secretary CT Young, former Mayor Andrew Young, and members of the Ebenezer Baptist Church – the Church of Martin Luther King Jr. – usually speak to the athletes during the week.

“Here this year, if it’s of the greatest interest, we can’t have that,” said Stokan. “This is disappointing.”

Despite all of this, Stokan maintains a positive outlook.

Stokan is also grateful for this year’s matchup and the impact of that game. The Group 5 team won the previous two games. Houston defeated Florida State 38:24 in 2015 and UCF defeated Auburn 34:27 in 2018. Stokan expects the matchup between the Bulldogs and Bearcats to be just as entertaining.

“This is college football, but by the end of the day both Florida State-Houston and Auburn-UCF teams were ready to play,” said Stokan. “I went to every training session and there wasn’t a team that didn’t want to be there. Anything can happen in every game.”
