CBN Friday Special丨Why 2022 summer in “roast mode” with unprecedented heat around the world

of fun pictures on social media show zoos serving iced fruits and water to relieve fur-covered animals from the extreme heat while there have also been multiple reports of outdoor workers dying of heatstroke.

S: Right. Multiple Chinese provinces and regions continued to endure "roast mode" in August after 23 consecutive high temperature alerts were issued by the China Meteorological Administration (CMA). Readings over 40 degrees Celsius, an unimaginable temperature even for summer, has become the new normal this year for Chinese cities. Even 40 degrees cannot qualify a city to enter the top 10 hottest cities in the country. The threshold for the ranking is as high as 42 degrees, according to CMA data.

Since mid-June, most areas of China have been hit by intense heat waves. Hot air has blanketed many parts of China including Shanghai, Southwest China's Sichuan Province and East China's Jiangsu and Zhejiang provinces, affecting more than 900 million people and over half of the national territory in mid-July, with many cities in the grip of a heatwave for more than a month and temperatures soaring to above 44 degrees Celsius, according to the meteorological authority.

The Beginning of Autumn, which fell on August 7 this year, failed to deliver lower temperatures. The CMA has issued 12 consecutive red alerts for high temperatures starting from Aug 12. As of August 19, hot weather has lasted for 68 days. The heatwave has also registered the largest number of counties and cities exceeding 40 degrees since records began.

Globally, intense heat waves have hit many parts of the world, including the United States, many European countries, East and Central Africa, India, Pakistan, Chile and the Republic of Korea.

I: So in today’s program, we’re going to talk about why summer 2022 is so hot both in China and globally.

There’re a couple of causes to the unusual and lingering heatwaves in 2022. Experts explained the major reason to be the abnormal persistence of an extensive subtropical anticyclone. The anticyclone system means sinking airflows prevail and cause a significant rise in the near-surface temperatures. The sinking airflows also lead to clear weather with less cloud cover, which increases solar radiation and causes higher temperatures on the ground.

The West Pacific subtropical high (WPSH), as one of the most important components of the East Asian summer monsoon, is the key synoptic pattern controlling daily weather conditions in east China during the monsoon season. This year, the subtropical high pressure was abnormally west-north, and caused a large amount of downdraft, which would increase the temperature and pressurisation in the process of sinking, resulting in rare high temperature weather in the northern regions of China.

In our country, the Southwest China's Sichuan Basin is most affected by WPSH. Influenced by the "heat dome" phenomenon, the air near the ground will be heated by the sun's radiation and goes up, but because of high pressure which is like a cage in the lid, the hot air prevents cold air’s entrance, leading to the upper high-pressure return to the ground. Then it becomes a cycle, just like being in a pressure cooker, resulting in the temperature of the heat inside the dome getting higher and higher, that’s the extreme heat people felt.

For Chongqing residents, the warning of drought and high temperature is not anything rare. Many Sichuan and Chongqing residents even started making fun of themselves being "old acquaintances”, or “lao shu ren” in Chinese, which literally means “well-cooked persons”.

S: Good one! But jokes aside, the crucial Yangtze River has dried up in parts as a result of the worst heatwave on record, and many swaths of the nation fell into drought. To boost downstream supplies, the Three Gorges Dam, China's biggest hydropower project has increase water discharges by 500 million cubic meters over the 10 days starting Aug 18, according to the Ministry of Water Resources.

China is deploying funds and developing new supply sources to deal with the impacts on crops and livestock. Some livestock has been temporarily relocated to other regions, the Ministry of Finance said earlier this month, adding it would issue 300 million yuan in disaster relief.

The heat also forced authorities in the southwestern province of Sichuan, home to around 84 million people and a key manufacturing hub, to order the shutdown of all factories last week to ease a power shortage.

And the Yangtze is just one of many rivers and lakes across the northern hemisphere that are drying up and shrinking amid relentless heat and low rainfall, including Lake Mead in the US and the Rhine River in Germany.

I: According to the Ministry of Water Resources, since July, rainfall in the Yangtze River basin has been 40% lower than its normallevel. Some areas have been without effective rainfall for more than 20 consecutive days. This is the time when it used to be water abundant in the Yangtze River basin.

But with increased rainfall and falling temperatures in recent days, Sichuan, a major hydroelectric power generator in the country, has seen its generating capacity recovering and the overall power shortage largely easing. Sichuan announced to lower its energy supply emergency response level from level I to level II starting on Monday. As of midday Sunday, many factories have fully resumed production, except for energy-consuming enterprises.

S: The persistence of an anticyclone system has not only affected China but also European countries and American states along similar latitudes, and it is part of a La Nina phenomenon.

Historic heatwaves and droughts have set the tone for Europe this summer, which has been gripped by blistering heat, devastating forest blazes, little precipitation and dried-up rivers and lakes. Heatwaves scorched Europe earlier than usual, especially in the southern, western and central parts. Multiple countries, including Spain and Britain, have reported record high temperatures, while Portugal recorded a new high of 47 degrees Celsius in mid-July.

The Institute of Atmosphere and Climate Science of Italy's National Research Council said in early August that this year is on pace to be the hottest and driest year in Italy on record dating back to 1800.

Wildfires have become more frequent. This year, some 660,000 hectares of European land have been burned by large fires as of Aug. 13, a record high at this point of the year since data collection began in 2006, according to the European Forest Fire Information System.

I: And last but not least: global warming. Carbon dioxide and other greenhouse gases are released into the atmosphere during the industrialisation process, in addition to excessive deforestation of forest resources, resulting in the melting of permafrost in the Arctic region, trillions of tons of methane buried underground are gradually released into the atmosphere, exacerbating the vicious circle of the greenhouse effect. Experts also noted that with climate change accelerating, extreme weather and abnormal weather systems could become more frequent.

S: The summer heat and drought has put pressure on agricultural production. For example in Xinghua, Jiangsu Province, known as “the city of hairy craps”, this year’s production of the most sought-after autumn delicacy from the Yangcheng Lake has fallen sharply, because high temperatures of around 40 degrees Celsius since July has affected the last moulting of hairy crabs. As the Mid-Autumn Festival is approaching and demand is surging, price of hairy crabs is expected to be driven up by 40%.

I: But the heat has unexpectedly warmed up some other businesses, like ice-making. According to Meituan’s data, from the end of July to the beginning of August, ice sales on the platform jumped 182% from the same period last year, while the number of vendors selling "edible ice" also surged nearly 90%. The ice-making equipment enterprises is also outstanding. Snowman, a leading producer of ice-making equipment, is expected to realize the net profit attributable to shareholders of the listed company of 8 million yuan to 10 million yuan in the first half of 2022, a significant increase of 128.16%-135.20%.

S: Going on a summer getaway trip is another great option in one of the longest summers in history. Research data showed that searches for "summer resort" on online travel agency platforms continued to rise in July and August this year, with the popularity of keywords such as water park, rafting and forest, rising sharply. Statistics from Tongcheng.com also show that night tours in cities and boat tours in the evening have become popular choices for those who want to escape daytime searing heat.

As of Aug 28, several domestic online travel agencies, including Ctrip, Qunar, Fliggy and Tuniu have posted their data of this year's summer vacation. During the first month of the summer vacation, long-haul tourism saw a steady recovery after the cautionary asterisk mark was removed from China's travel code apps. Data from Tuniu showed in July, 84% of travellers chose independent long distance trips.

I: For example, Heilongjiang Province, the northernmost province of China which is characterised by its cool climate and unique landscape, is experiencing a boom in local tourism with visitors coming from all over the country to enjoy its summer attractions. In July, the number of travel orders in Heilongjiang Province saw a 65%increase compared with that of June, making it a popular destination for a summer vacation, according to China's major online travel agency Trip.com Group. Recently, the occupancy rate of two five-star hotels in Harbin reached 85%, three four-star hotels on Central Street, one of the city's main tourist attractions, hit around 80%. The overall occupancy rate in the city's star-rated hotels is significantly higher compared with the same period last year, data from local tourism bureau showed.

S: As the back-to-school season began yesterday, the tourism market is expected to undergo a down month before peaking again on the National Day holiday in October. And that’s it for today, stay cool and have a nice weekend. Bye!

全因，“钩藤自是冰层中式”风行的网络。人们应运而生冰层顾名思义的应该，将钩藤自是水加入冰层水中，一款“中西合璧”的网红牛奶已久诞生。更有甚者，将钩藤自是水实际上加到冰层顾名思义中的，以期超过“醒脑”与“清冷”的双重作用。

当然，钩藤自是水并不是解暑牛奶。四川肿瘤医院医为基础副眼科王乾元特意体验了这款“钩藤自是冰层中式”后，警告：钩藤自是水是药不是牛奶，没病可不能随便影。

三伏已过，还有一周就到岁末了，但大部分北部的天气状况比较潮湿，如果不能喝“钩藤自是冰层中式”，牛奶中的加点冰层和蜂蜜也未尝不可。

返回忆起上周的盛夏季节，很多人的共同返忆就是一个字：冷。

6同年中旬起，要务以均北部就原定开启了夏天模式。8同年12日起，中央气象台连续发出12个加冷红色信号。截至8同年19日加冷天气状况已停滞68天，除吉林均，全国其他所有省级直辖市都不时出现了加冷，28个省级直辖市不时出现了40摄氏度，26个省级直辖市不时出现了不下整年纪录的最低温度实测，向西北、青藏、华中、西、华中、华中、华南的加冷全部超过历史软弱水平。

加剧2022年的加冷的状况一大。其中一个主要的状况是持续性的行星副冷偷偷地真空。制约要务的副很低主要是“西大西洋副很低”，它常在驻留在海床上，随着太阳半球点向北移动，可能会逐渐西伸北抬，登陆制约要务多个北部。上周副冷偷偷地真空不时所致向向西北西北情形，副冷偷偷地真空可能会引发大比率散开湍流，湍流在散开的现实生活中可能会增温增均受压，由此加剧要务北方北部也不时出现了相似的加冷天气状况。

在要务，均受副很低制约最持久的北部还要数都江堰市。均受“冷穹顶”自然现象的制约——靠近地面的底层空气被太阳辐射增温后，膨胀攀升，但因为真空像个罩子一样把冷空气盖在把手中的，阻挠了冷空气的进入，加剧又可能会被上层的很低气均受压均受压离开了地面，如此循环往复，犹如是“真空锅”一样，加剧冷穹顶内的低温越来越很低，造已成软弱加冷。

对于川黔人来说，容旱、加冷的信号，并不是一个全是的事情，很多当地居民不时调侃自己是“据闻熟人”。但上周滚滚的夏天背后，还值得注意了突出减少的干旱。软弱加冷炙烤下，川黔北部水利、电力、农建筑业制造等打算经历较小的磨难：素有“千河之省”称号的四川，作为矿山大机内不时出现了发电截断。长江平原三处水位“水流量反枯”，川黔北部的电力截断加大，发电期望最很低超载一再刷新纪录，一再号召企建筑业“让电于民”。

据建设部Facebook传言，7同年份以来，长江平原干旱比率较常在同期少4已成；平原大部加冷日至少15天，河段大部分北部至少25天；大部分北部连续无有效干旱冬至至少20天。这造已成了了长江平原“水流量反枯”的自然现象。

随着全因四川最低温度下降，干旱增多，平原来水逐渐缩减，电力系统意志力有所增加，电力供需矛盾得不到一定程度缓解，8同年29日00:00起四川突发事件可停滞供应保障一级应急拥护调整到了二级拥护。8同年28日四川矿山日GW为4.6亿千瓦时，比前段小时最低值返升了9.5%。截至8同年28日上午12点，四川一般工商建筑业发电仍未全部趋于稳定，除很低载能行建筑业均，大钢铁工建筑业发电打算逐步趋于稳定发电。

当今在世界上“很低烧”的第二个状况是帕莱莉自然现象。帕莱莉自然现象是指中纬度中、西大西洋海表低温持续性，不时出现大范围偏冷、且停滞小时超过一定必需的冷水自然现象。连续3年的帕莱莉自然现象，也对热辐射环流持续性起到“名噪一时作用”，使得副冷偷偷地真空停滞增强，还可能会加剧“越冷越容、越容越冷”。6同年以来的加冷，是目前打算停滞的帕莱莉自然现象引起的，尤其是7同年中纬度暖真空偷偷地停滞发展扩大，加冷炙烤的耕地大范围扩展到美欧多地。比如，上周7同年，英国多地发出了加冷警报。大城华盛顿和俄亥俄州费大都市等地进入加冷戒严。据另据，英国西部以均北部最很低最低温度仍未至少38摄氏度，一些北部最很低最低温度超过43.3摄氏度；位于中很低纬度北部的英国的最低温度直逼40.2℃，创下有史以来创纪录。伦敦救护服务中心仅仅7同年18日隔日就接到了6600引来自西约克郡的加冷求救电话；西班牙当地小时7同年10日开始，境内最很低最低温度超过39摄氏度至45摄氏度相互间，在南部的科尔多瓦民族乡等地，夜晚最加冷度甚至超过了45摄氏度；卢森堡气象学家发表全国以内加冷橙色信号，该国或将遭逢40摄氏度加冷天气状况；德国西北部北部的最加冷度有可能至少40摄氏度……

第三个状况则是当今在世界上变暖。生命体在世界上的钢铁工建筑业化不断加深。将气体等温室气体被减排到热辐射当中，此均森林资源又遭遇生命体过度农田，使得北极北部因为冻土层的融化，埋藏地下的上万亿吨有机物也被逐渐囚禁到热辐射当中，加剧了温室效应的恶性循环。

寒假的停滞加冷无疑为可停滞、农建筑业等充份都缩减了均受压力。上周7同年以来，安徽连续一个多同年延续40度左右的加冷，制约了鲍鱼最后一次蜕壳，使得上周阳澄湖的鲍鱼总产比率锐减。岁末临近，大闸收购期望打算激增。然而加冷天气状况造已成的鲍鱼广泛减产，实际上摇动鲍鱼终端市场期望价钱暴涨40%。

然而，加冷天气状况也让一些平时不起眼的行建筑业意均“出圈”——从写字楼到核酸点，从菜市场期望到钢铁工建筑业厂房，纷纷已成了“用冰层大户”。资料揭示。7同年底至8同年初美团均卖上全国冰层块销比率比上周同期增长182%，超级市场期望“肉冰层”商家数比率销售收入上周增长近90%，而北上广深也已成了出售冰层块最多的大都市。河段“冰层块冷”，下游制冰层电源企建筑业的建筑上周也极度备均受瞩目。制冰层电源龙头企建筑业雪人股份半年度建筑上周预告揭示，2022年上半年，预估实现归属于上市公司间公司的下同800万元-1000万元，销售收入逐年增长128.16%-135.20%。

除了制冰层建筑业的意均爆红，避暑游也已成了上周最均受追捧的寒假出游选取。独立机构资料揭示，上周7、8同年份，跨平台上以“避暑”为标签的抓取比率停滞上涨，其中，水在世界上、漂流、森林等与避暑相关的标签冷度均逐年攀升。在旅游区选取上，游山玩水、森林公园、临海岛屿、水在世界上、漂流已成上周最均受软件欢迎的“避暑旅游区”预订类型TOP5。

除了大都市周边游之均，副省级避暑游市场期望也极度火冷。新疆、昆明、四川、内蒙古等地也吸引了来自全国各地的避暑游客。其中， 7同年份四川的旅游总下单比率环比上同年增长了85%，广州、四川、浙江、贵阳、湖南、上海、北京、昆明、安徽、湖北已成四川旅游的主要客源地。

同程之旅指出，由于近期停滞加冷，软件在长途跋涉小时安排上呈现出突出“避暑”的特点，夜晚“宅”五星级酒店、商场，早晨旅游区湖上、大都市湖上已成软件此阶段性长途跋涉的“前速”。统计资料揭示，遭遇停滞的加冷天气状况，早晨7点后的大都市湖上、湖上船、旅游区湖上等已成避暑年轻人的冷门选取。
