# Accurate data and mission By [Betty](https://paragraph.com/@betty-10) · 2022-05-13 --- At noon on May 4, the “peak mission 2022” scientific research of Everest successfully reached the top, and the arduous tasks of building stations on the top of the earth, sampling ice and snow, and measuring the thickness of ice and snow on the top of the peak were successfully completed. “Zasidler!” “Heaven is beautiful!” Seeing the picture of climbing back from the front, the atmosphere in the Everest base camp at an altitude of 5200 meters was jubilant. There are some people who, after cheering, quickly put into the next stage of work - to provide meteorological support for the withdrawal of scientific expedition climbers. They are the “westerly monsoon synergy and influence team” (hereinafter referred to as the “team”) composed of the Qinghai Tibet Plateau Research Institute of the Chinese Academy of Sciences, the Chinese Academy of Meteorological Sciences and the Meteorological Bureau of the Tibet Autonomous Region. They are also the authoritative expert team responsible for the meteorological support task of the scientific research on Everest. At 12 noon on the 4th, before climbing the summit, the mountaineers who were erecting the world’s highest automatic weather station at 8830 meters above sea level on the north slope of Everest received a special forecast for the comprehensive scientific research of Everest, which collected all kinds of meteorological observation data and gathered the wisdom of experts in the front and behind the Central Meteorological Observatory and the Meteorological Bureau of Tibet Autonomous Region. In the special report, the 6-hour wind direction, wind speed, temperature and sky condition forecast of each altitude layer from 7000 meters to 8000 meters and 8000 meters to 9000 meters of Everest, the 12-hour forecast of Everest base camp and the weather trend forecast of the coming week are clear at a glance. Ma Yaoming, leader of the unit and researcher of the Qinghai Tibet Plateau Research Institute of the Chinese Academy of Sciences, said that the team has two main tasks: one is to carry out vertical atmospheric detection by using high-tech equipment such as radio sounding system, laser wind radar and microwave radiometer; Second, based on the real-time observation data obtained by the above observation instruments, carry out extreme weather monitoring and prediction, and provide meteorological support services for mountaineering scientific research teams. According to the arrangement, at 8:00 and 20:00 every day, the team uses the radio sounding system to detect the changes of temperature, humidity and air pressure at an altitude of 20000 meters on the earth’s surface. Starting from May 2, densified radiosonde observations at 2:00 and 14:00 have been added to grasp the real-time weather conditions of Everest to the greatest extent and provide the latest and latest meteorological data for Everest Summit and station construction. The Chinese Academy of Meteorological Sciences has also tested the ultra-low temperature automatic weather station independently developed and assembled in its base camp, set up a domestic microwave radiometer, carried out continuous atmospheric vertical temperature and humidity observation, and carried out the same ball observation test of domestic radiosonde, which can provide strong support for the scientific research work in the Everest area and the R & D and improvement of domestic meteorological instruments. Dai Huaguang, member of the detachment and deputy director of the meteorological observatory of Tibet Autonomous Region, introduced that the meteorological factors affecting the “window period” of Everest summit are mainly the temperature, humidity, wind direction and wind speed at different heights from 6000 meters to 9000 meters above sea level, among which the wind has a greater impact on the summit. “This morning, the wind speed above 8000 meters on Mount Everest is small, which is conducive to rush to the top.” Dai Huaguang said that since arriving at the base camp of Everest, the unit has provided nine special forecasts for the scientific research team. In fact, this is not the first time Dai Huaguang has participated in the meteorological support task of Everest summit. In 2020, as the chief forecaster, he participated in the meteorological service of Everest elevation survey. He said happily, “the weather is especially ‘awesome’ this time. With the support of scientific research data, the support task is much easier than last time.” Behind the “relative ease” is the support of the sounding observation of the base camp of Everest and the meteorological observation data at all altitudes of Everest, as well as the three-dimensional interpolation prediction product specially developed by the National Meteorological Center, which includes the prediction of wind speed, air temperature, precipitation and other elements at 6000, 7000, 8000 and 9000 meters above sea level. The summit mission was successfully completed, and the safety withdrawal and follow-up scientific research tasks continue. --- *Originally published on [Betty](https://paragraph.com/@betty-10/accurate-data-and-mission)*
