These "magic skills" are helping Chinese weather

This summer, the northern hemisphere has encountered extreme high -temperature weather, allowing the world to recognize the significant impact of climate change. At the 2022 China International Services Trade Fair (referred to as the "Service Trade Club"), which opened on September 1, the World Meteorological Organization and the China Meteorological Administration jointly organized the first climate economy summit forum and the "2022 Meteorological and Global Service Trade Exhibition" Series exhibition. "Global Times" reporter experienced how technology helps the development of China's meteorological cause at the scene.

Zhuang Guotai, director of the China Meteorological Administration, said that in the context of global climate change, extreme weather and climate events are widely, frequent, re -incident, and concurrency. Since June of this year, high temperature, floods, and forest fires have emerged in many places, which has a serious impact on global economic and social development, food security, and ecological security. Energy transformation and ecological civilization construction has become increasingly urgent. More and more countries and people have realized how to adapt and slow the negative effects brought by climate change will be a major challenge facing humanity in the future.

Early forecasting early warning to rely on technology to provide global weather is an important means to deal with climate change. On March 23, 2022, the United Nations Secretary -General Gutres announced that the United Nations would take new measures to ensure that everyone on the planet could be protected by the early meteorological early warning system within 5 years. "Global Times" reporter noticed that many Chinese companies exhibited advanced meteorological technology and equipment at the service trade association. Aerospace New Meteorological Technology Co., Ltd. exhibited a variety of meteorological radar products, which can be called the "sentinel" of disaster prevention and mitigation. According to reports, it takes 6 minutes compared to the conventional Dopler weather radar scanning a week. The X -band phased array weather radar developed by the company only takes 1 minute and a half to complete the scan, which can observe the weather elements faster and more accurately. Realize real -time monitoring of catastrophe, hail, thunderstorms and other catastrophic weather. In addition, in the process of extinguishing Chongqing mountain fires recently, artificial rain increase operations play an important role. However, artificial rainfall needs to understand the specific situation inside the clouds. In this regard, the millimeter -wave test cloud radar can come in handy. It is the most effective equipment that is currently achieving cloud fineness detection, which is equivalent to "doing CT" to the cloud. Provide effective data for the weather to affect weather.

At the exhibition, a mechanical dog named "ULD3000" is actually a delicate unmanned terrestrial detector that is actually designed to replace human observer to monitor temperature and humidity in extreme environments of minus 40 degrees and 80 degrees, and Meteorological observation elements such as air pressure, wind speed wind direction, solar radiation, and particulate matter.

In addition to ground equipment, the Global Times reporter learned at the "Meteorological and Global Service Trade" booth that China already has multiple weather satellites, including the highest static meteorological satellite Fengyun No. 4 satellite B satellite B satellite, which includes the highest spatial resolution, its The time and space resolution is increased to 1 minute and 250 meters. It is known as "the wind and clouds can be visible from the naked eye", which is of great significance for the monitoring and early warning of strong stream weather, especially sudden small and medium -scale weather system monitoring.

Relying on these advanced observation methods, such as today's weather forecast is more accurate, and can even be customized. For example, the "variable resolution self -adaptive meteorological forecasting system" on display is based on north Dou+high -scoring digital earth as the basis, combined with meteorological data and artificial intelligence technology, which can provide a specific time and region that accurate the accuracy of tens of meters according to the needs of the user. Weather forecast, these characteristics help the drone planning flight route or organizing outdoor competitions. (Ma Jun) ▲
