新闻报道1+1丨寒潮来袭,怎样解决?视頻来源于:cctv新闻。

cctv新闻11月9日报导,11月3日,中国气象台公布2021年全国首个寒流黄色预警。从11月4日起,在我国迈入转秋至今最強寒潮天气,多地“一夜立冬”。13日前后左右,在我国还将迈入新一波降温全过程。下一波强冷空气还会继续那么猛吗?恶劣天气气侯事情因何高发高发?《新闻1 1》联线国家气象局国家气侯中心专家教授郑志海,给你解疑释惑。

寒潮来袭,是不是代表着今年冬天可能是冷冬?

国家气象局国家气侯中心专家教授 郑志海:

一次寒流全过程并不能说这个冬天就一定是冷冬。有关冷冬,大家有较为确定的国家的规范和严苛界定。最先它是对冬天三个月的均值的温度来讲,跟降温的频率和范畴都是有挺大的关联。大家有“单站冷冬”“地区性冷”和“全国冷冬”三个级别。在其中仅有全国各地50%之上的网站都出現了温度显著稍低的状况才可以算“全国冷冬”。所以说分辨这个冬天是不是为冷冬,大家必须等冬天三个月完毕以后,依据降温的频率和范畴再去分辨。

Biden declared healthy and 'fit' for presidency after exam******

AFP。

US President Joe Biden speaks to members of the press after a Marine One arrival at the South Lawn of the White House November 19, 2021, in Washington, DC.。

President Joe Biden got a clean bill of health from the White House doctor on Friday after undergoing an extensive, routine check-up during which his powers were briefly transferred to Vice President Kamala Harris.。

"The President remains a healthy, vigorous, 78-year-old male, who is fit to successfully execute the duties of the Presidency, to include those as Chief Executive, Head of State and Commander in Chief," Kevin O'Connor, the White House physician, wrote.。

The detailed report said that Biden did have "perceptibly stiffer and less fluid" motion while walking than a year ago, and suffered "increasing frequency and severity of 'throat clearing' and coughing during public speaking engagements."

However, these two symptoms were not considered of immediate concern and did not appear to result from serious conditions, O'Connor's letter said.。

On a raft of tests, Biden came out with high marks.。

He has "no signs of heart failure," "no dental issues," has no "suspicions for skin cancer," and his eye health "is reassuring."

One reason for that solid report may be the doctor's finding that "the president does not use any tobacco products, does not drink alcohol, and he works out at least five days a week."

Biden, who turns 79 on Saturday and is the oldest president in US history, takes three common prescription medications and two over-the-counter medicines, as well as wearing contact lenses, the letter revealed.。

He measures 1.82 meters, weighs 83.46 kg and has a body mass index of 25.。

A smiling Biden returned to the White House from his checkup at Walter Reed hospital earlier, saying "I feel great."

"We're in great shape," he said, wearing his trademark aviator sunglasses.。

Historic 1.25 hours。

While the annual visit to Walter Reed hospital was routine for a president, the requirement for Biden to transfer power while sedated during a colonoscopy exam made history.。

For one hour and 25 minutes, Harris was the first woman to hold presidential power in the United States. She is already the first female vice president.。

The White House press office said that official letters to Congress declaring the temporary transfer of power were sent at 10:10am (3:10pm GMT). "The president resumed his duties at 11:35am," (4:35pm GMT), the White House said in a statement.。

"Today that was another chapter in that history for many women, young girls across the country," Press Secretary Jen Psaki said, noting Harris' trailblazing role.。

The details on Biden's health were being closely watched, given speculation on whether he will stand by his stated intention to seek a second term in 2024.。

The positive medical assessment mirrored an earlier letter from Biden's physician during his election campaign in December 2019, when he was described him as "a healthy, vigorous, 77-year-old male, who is fit to successfully execute the duties of the presidency."

He was vaccinated early on against COVID-19, and received a booster shot in September.。

China's benchmark interbank gold prices lower Wednesday******

BEIJING, Dec. 8 (Xinhua) -- China's benchmark prices for spot interbank gold transactions were lower Wednesday, according to the China Foreign Exchange Trade System.。

The benchmark price for gold of 99.95 percent pure or above stood at 366.7 yuan (about 57.59 U.S. dollars) per gram, down 0.78 yuan from the previous trading day, and that for gold of 99.99 percent pure or above went down 0.52 yuan to 367.47 yuan per gram.。

Spot transaction prices on the interbank price inquiry market are allowed to rise or fall within 15 percent from the benchmark prices each trading day.。

The interbank gold price inquiry business was introduced in 2012 to enhance market liquidity and enrich trading models. Enditem。
