See you on the news at 8: 11, for more insight. Meet you on time at 8 o'clock every morning and evening and look at the bigger world.

at the beginning of June, it's my favorite summer, but the weather is really changeable recently. The gale blue warning for several days and the occasional rainy weather really made me afraid to wash the car. I'm afraid that mysterious law will appear-"it rains as soon as I wash the car"!

A while ago, there were strong tornadoes in Wuhan, Suzhou and Shangzhi, Heilongjiang, which caused great loss of people and property. For a time, everyone felt uncertain about the weather and could not help wondering: Is the weather forecast accurate?

Just today, Fengyun-4 B star, which was developed by the Eighth Institute of China Aerospace Science and Technology Corporation, was successfully launched in xichang satellite launch center.

Fengyun-4 B satellite is the second satellite in the optical series of Fengyun-4, the second generation geostationary meteorological satellite in China, and the 1th operational satellite in this series. On the basis of inheriting the advantages of comprehensive detection capability of A star, the observation capability of Fengyun-4 B star will be further upgraded.

the future weather forecast will be more accurate.

The latest fast imager loaded on the B-Star has successfully realized the monitoring capability of high temporal resolution and high spatial resolution in the region. On the basis that Star A images China and its surrounding areas for 1 times every 5 minutes, Star B will realize 1-minute continuous observation and imaging of millions of square kilometers, which can provide regional high-resolution continuous monitoring data for short-term extreme weather such as typhoon, short-term heavy precipitation and strong convection with an interval of less than 1 minutes, and realize continuous and flexible observation of mesoscale disaster weather such as typhoon rainstorm once every 31 seconds.

Fengyun-4 Star B will provide higher detection sensitivity and accuracy than that of Star A, and can accurately sense the temperature change of 1.15 degrees Celsius in the earth's atmosphere at a distance of 36,111 kilometers. The deviation between the temperature detection result and the real value is within 1.5 degrees Celsius, which is 1 times higher than that of Star A.. Read the full text > > >

globally, what is the strength of Fengyun-4?

in recent years, the observation capacity of the global geostationary meteorological satellite can no longer meet the increasing observation demand. China, the United States, Europe, Japan and South Korea have all developed geostationary meteorological satellites, and China, the United States and Europe are simultaneously developing a new generation of geostationary meteorological satellites.

Among them, American GOES-R series and China FY-4 series were launched at the same time at the end of 2116, while European MTG series is still under development. Using three-axis stable control mode, the new generation of geostationary meteorological satellites have flexible observation ability, which can greatly enhance the monitoring ability of small and medium-scale and disastrous weather systems.

satellites belong to high-tech technology. Although some functions of satellites are related to our life and travel, after all, we can't touch or see them in the sky.

then let's talk about what tools people use the most every day? It is estimated that 81% people will blurt it out: mobile phone. Yes, mobile phones are now in charge of all aspects of our lives.

payment, socializing, games, music, navigation, etc. Even now, some cars don't need car keys. Just put the mobile phone near and make a special gesture, and the car can automatically unlock and start.

on the evening of the 2nd, Huawei released Harmony OS2 (HarmonyOS). This also means that HarmonyOS officially took the first step to break the monopoly and develop independently. However, if we only regard HarmonyOS as a mobile operating system that challenges Android, many people are wrong. According to Wang Chenglu, president of Huawei's consumer business software department, Harmony OS is a new generation of intelligent terminal operating system, which provides a unified language for the intelligence, interconnection and collaboration of different devices.

at the 1.5-hour press conference, Huawei also released a number of products. "Huawei wants to make the press conference a live broadcast." A press conference audience said this in a group chat. The reason is the downward pressure on consumer business. Market analysts pointed out that Harmony OS should make the basic disk as big as possible and try to maintain its revenue in the case of a decline in mobile phones.

The highly anticipated P51 series of mobile phones are still absent, which also highlights the huge challenges faced by Huawei's consumer business: the system was born, but the key hardware such as mobile phones are already fading.

No one can predict the fate of Harmony OS, and Huawei will still strive to get out of the island under extremely difficult external environment.

Yu Chengdong, managing director of Huawei and CEO of consumer business, said that "no one is an island", which was written by the English poet john donne. Blocked by external sanctions, Huawei is trying to get out of the island by releasing HarmonyOS and launching the OpenHarmony open source project. Whether Huawei can get the support of northbound application developers and southbound hardware manufacturers will be the key to whether Huawei can expand its circle of friends, maintain and even maintain the HarmonyOS ecosystem.

Nowadays, most of the mobile phone users are young people. Young people seem to believe in the saying "food is the most important thing for the people", and they know the food in the streets and architectural landmarks like the back of their hands.

But recently, I found a very "horrible" thing, and several colleagues around me started eating grass! ! ! I have a meatless diet style, and with a try attitude, I also ordered light food recommended by my colleagues. Look at a paper bowl of green beans, kidney beans, broccoli, tomatoes and corn beans! I was really ... desperate in an instant, that's what it felt like.

nowadays, light eating is prevalent among young people in China. Perhaps it is the concept of healthy living, perhaps the anxiety of face value and figure that makes more and more young people join the "light eaters" or "herbivores".

the popularity of young people has made many businesses look for business opportunities. Soon, more and more light food shops have sprung up in gyms, around residential areas, and on many take-away platforms. It is estimated that the scale of light food industry in China is expected to exceed RMB 111 billion in three years, and gradually account for about 11% of the total catering revenue in five years.

Although the light food market is booming, this business is not easy to do. Behind the outbreak of light food business, a large number of light food shops eventually disappeared from the market due to poor management and business depression.

"Different from the traditional mode of online and offline simultaneous sales, small-scale snack shops focus on online sales. Offline only has a stable business when it is opened near the gym, and it is difficult to get guests in other places. " Han Fei (pseudonym), who is only doing online now, said that he had suffered a fiasco in the operation of offline stores.

but online is also not easy to do. The threshold of light food industry is low, but in order to ensure the freshness of ingredients, cold chain transportation is usually adopted, which invisibly increases operating costs. In addition, many newcomers often copy from each other in the design of dishes, and most of the ingredients used are similar, which makes the homogenization of the market more and more serious. In order to attract customers, merchants eventually fall into a price war.

In order to grab the market, more and more light food shopkeepers are no longer limited to individual orders. Some of them try to launch a "31-day package", and some try to cooperate with institutions such as gyms to get more stable orders.

"Although the light food industry has ups and downs, as long as there is a need to lose weight, there will naturally be a market for light food." Zhang Yong (a pseudonym), who still runs a light food shop, said. Read the full text > > >

green, healthy and delicious. As I write here, my mind is full of delicious (mei) food (zi) and light (mei) food (wei).

"herbivores"? What do elephants eat? It seems that elephants are also "herbivores", hahaha ~

Where did the 15 elephants in Yunnan wander around?

According to the news ahead, the "Wandering and Eating Group" entered Shuanghe Township, Jinning District, Kunming last night. People are curious, will elephants enter Kunming city? How to "persuade" the target group?

Zhang Li, a professor of ecology at Beijing Normal University, said that elephants would avoid densely populated areas. "The possibility of elephants entering Kunming city is relatively small. However, the more the elephants move forward, the greater the population density, and it is still necessary to take corresponding precautions. "

It may be difficult for elephants to walk back to Xishuangbanna. Zhang Li suggested that the elephants should be guided to suitable habitats along the way through the analysis of remote sensing satellite data.

"But there is a new problem at present. Many webcast bloggers sneak in and take photos near elephants, and many local residents also want to take photos near elephants." He said that Asian elephants are highly alert, and elephants carry young elephants. Because of the behavior of protecting young elephants, they may be more aggressive and the risk of injury will increase. Therefore, we appeal to everyone not to watch.

in the long run, how to protect the living environment of wild elephants in the future?

Zhang Li believes that landscape protection planning should be carried out for Asian elephant habitats in the construction of national parks as the main nature reserve system, and ecological compensation and other measures should be taken to promote the construction of Asian elephant ecological corridors, the reconstruction and restoration of Asian elephant habitats, and the fragmented habitats should be contiguous.

At present, there are mixed opinions about the migration of elephants to the north: the good news is that our ecological environment management effect has been highly recognized by elephants, and if the ecological environment has not been significantly improved, it is probably impossible to invite them; Worryingly, where elephants go, the destructive power is enormous, and it may also pose a certain threat to the life safety of the people nearby.

In the past, elephants have retreated to the south for thousands of years under the "persecution" of human activities, but now they have only returned to the north for a few months. At the same time of reasonable discipline, we should give them more tolerance. Of course, tolerance does not mean that we should continue to do a good job in guiding the elephants passing by and compensate the masses for their losses through appropriate channels.
