Weather forecast Jinning
Early June is 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 there will be that mysterious law-"it rains as soon as I wash the car"!
A while ago, there were strong tornadoes in Wuhan, Suzhou and Shangzhi, Heilongjiang, which caused huge losses 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 developed by China Aerospace Science and Technology Corporation No.8 Institute 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 stationary meteorological satellite in China, and it is also the 1 operational satellite of this series. On the basis of inheriting the advantages of comprehensive detection ability of A-star, the observation ability of Fengyun-4 B-star will be further upgraded.
The future weather forecast will be more accurate.
The latest fast imager carried by the B-star has successfully realized the monitoring ability of high temporal resolution and high spatial resolution in this area. On the basis of 1 minute imaging of China and its surrounding areas every 5 minutes, Star B will realize continuous observation and imaging of one million square kilometers at 1 minute, which can provide regional high-resolution continuous monitoring data with intervals less than 1 minute for short-term extreme weather such as typhoon, short-term heavy precipitation and strong convection, and realize continuous and flexible observation of mesoscale disaster weather such as typhoon rainstorm once every 30 seconds.
Fengyun-4 B star will provide higher detection sensitivity and accuracy than A star, and can accurately sense the temperature change of the earth's atmosphere at a distance of 36,000 kilometers. The deviation between the temperature test result and the real value is within 0.5 degrees Celsius, which is 1 times higher than that of A star ... Read the full text >>& gt.
Looking around the world, what is the strength of Fengyun-4?
In recent years, the observation ability of global geostationary meteorological satellites can no longer meet the increasing observation demand. China, the United States, Europe, Japan and South Korea have all developed geostationary meteorological satellites, while China, the United States and Europe have also developed a new generation of geostationary meteorological satellites.
Among them, the GOES-R series in the United States and Fengyun -4 series in China were listed at the end of 20 16, while the MTG series in Europe is still under development. Using three-axis stable control mode, the new generation of geostationary meteorological satellites have flexible observation ability, which can greatly improve the monitoring ability of small and medium-scale and severe 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 80% 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. As long as you put your mobile phone nearby and make a special gesture, the car will automatically unlock and start.
On the evening of the 2nd, Huawei released the Harmony OS2 (HarmonyOS System). This also means that the HarmonyOS system has officially taken 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, president of Huawei's consumer business software department, it 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 conference live." A press conference audience said this in a group chat. The reason is the downward pressure on consumer business. Market analysts pointed out that HarmonyOS system should make the basic disk as large as possible, and strive to maintain revenue in the case of declining mobile phones.
The long-awaited P50 series of mobile phones are still absent, which also highlights the great challenge faced by Huawei's consumer business: the system was born, but the key hardware such as mobile phones has been fading.
No one can predict the fate of HarmonyOS system, and Huawei will still strive to get out of the island in an extremely difficult external environment.
Yu Chengdong, managing director and CEO of Huawei's consumer business, said that "no one is an island", which was written by British poet john donne. Hindered by external sanctions, Huawei is trying to get out of the island by releasing the HarmonyOS system 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 and maintain and even maintain the ecosystem of HarmonyOS.

Nowadays, most mobile phone users are young people. Young people seem to believe that "food is the most important thing for the people" and know the food and architectural landmarks on the street like the back of their hands.
But recently I found a very "horrible" thing, and several colleagues around me began to eat grass! ! ! I am a meatless diet, with a try attitude, and ordered light food recommended by my colleagues. Look at a paper bowl with green beans, kidney beans, broccoli, tomatoes and corn beans! I'm really ... desperate in an instant, that's how I feel.
Nowadays, light diet is very popular among young people in China. Perhaps it is the concept of healthy living, or the anxiety about face value and figure that makes more and more young people join the ranks of "light eaters" or "herbivores".
The pursuit of young people has made many businesses see business opportunities. Soon, more and more light food shops have mushroomed in gyms, neighborhoods and many take-away platforms. It is estimated that the scale of China's light food industry is expected to exceed 1000 billion yuan in three years, and gradually account for about 10% of the total catering revenue in five years.
Although the light food market is booming, it is not easy to do business. Behind the outbreak of light food business, a large number of light food shops eventually disappeared from the market due to poor management and sluggish business.
"Unlike the traditional online and offline catering mode, small-scale light food shops are more focused on online sales. Offline only has a stable business near the gym, and it is difficult to have 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 it's not easy to do it online. The threshold of light food industry is low, but in order to ensure the freshness of ingredients, cold chain transportation is usually used, 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 market homogenization more and more serious. In order to attract customers, merchants eventually fell 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 "30-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 someone has the need to lose weight, there will naturally be a market for light food." Zhang Yong (pseudonym), who still runs a snack bar, said. Read the full article >>& gt
Green, healthy, delicious, writing here, my mind is full of those delicious (plum) flavors (purple) and light (plum) foods (flavors).
"Herbivores"? What do elephants eat? It seems that elephants are also "herbivores", hahaha ~
15 Where did the elephant go in Yunnan?
News ahead, the "shopping group" entered Shuanghe Township, Jinning District, Kunming last night. People are curious, will elephants enter Kunming city? How to "convince" the target group?
Zhang Li, a professor of ecology at Beijing Normal University, said that elephants would avoid densely populated areas. "Elephants are less likely to enter downtown Kunming. However, the more the elephant moves forward, the greater the population density, and it is necessary to take corresponding precautions. "
It may be difficult for elephants to walk back to Xishuangbanna. Zhang Li suggested that elephants should be guided all the way to a suitable habitat through the analysis of remote sensing satellite data.
"But there is a new problem. Many bloggers sneak in and take photos near elephants. Many local residents also want to take pictures near elephants. " He said that Asian elephants are very vigilant, and elephants will take their young. Because of the behavior of protecting young elephants, they may be more aggressive and the risk of injury will increase. So I urge everyone not to look.
In the long run, how to protect the living environment of wild elephants in the future?
Zhang Li believes that in the construction of nature reserve system with national parks as the main body, landscape protection planning should be carried out for Asian elephant habitats, ecological compensation and other measures should be taken to promote the construction of Asian elephant ecological corridors, rebuild and restore Asian elephant habitats, and fragmented habitats should be contiguous.

At present, there are different opinions on the issue of elephants moving northward: the good news is that the effectiveness of our ecological environment management has been highly recognized by elephants. If the ecological environment has not been significantly improved, it is probably impossible to invite them; What is worrying is that wherever elephants go, their destructive power is enormous, and they may also pose a certain threat to the lives of people nearby.
In the past, elephants have retreated to the south for thousands of years under the persecution of human activities, but now they only return to the north for a few months. While reasonably disciplining, we should give them more tolerance. Of course, tolerance does not mean that we should continue to guide the passing elephants and compensate the people for their losses through appropriate channels. Read the full article >>& gt
