Accurate weather prediction can help the event be held safely and orderly, and in order to do a good job in the meteorological guarantee of the Hangzhou Asian Games, the meteorological department uses a number of intelligent observation technologies to escort the event.
On September 22, overcast with light rain, 22 °C ~ 26 °C This is a common weather forecast in life. In scope, it can be accurate to the administrative area of a city; On the time span, it can be accurate to one hour. However, such accuracy is far from enough in terms of meteorological support for Asian Games events.
The weather forecast of the Asian Games must not only be detailed to each venue, but also in large-scale events such as the opening and closing ceremonies, and even achieve "minute-level" accurate forecasting. In addition, in addition to the six meteorological elements of wind speed, wind direction, air temperature, air pressure, humidity, and precipitation, according to the characteristics of different events, the Asian Games meteorological service also needs to provide personalized data, such as measuring sand temperature in beach volleyball stadiums and monitoring water temperature in triathlons. Why should the Asian Games meteorological service be so detailed, and how can it be so detailed? We came to the Asian Games Meteorological Observatory with questions.
Shen Hangfeng, chief forecaster of the Asian Games Meteorological Observatory: Weather is still closely related to our sports events, first of all, it is related to the safety of athletes. For example, like equestrian competitions, horses are more sensitive to lightning and high temperatures. Once it is frightened, or in bad condition, it is easy to affect the rider. Another example is water sports, if the water temperature is too low when athletes go into the water, it will lead to hypothermia, which may also affect the health and safety of athletes.
Precise observation is the basis of meteorological support. In the regional meteorological observation station, about 600 meters away from the Olympic Sports Center Stadium, the main venue of the Hangzhou Asian Games, there are many smart devices monitoring the weather in real time. With the help of artificial intelligence recognition model, this observer can automatically judge weather conditions, and timely feedback key data such as cloud cover, cloud shape, and cloud height to the meteorological data platform for analysis and reference by Asian Games weather forecasters.
In addition, in order to make accurate forecasts of small areas of the venue, in the main stadium of the Hangzhou Olympic Sports Center, the staff also built a number of micro-weather stations in the venue, and laid canopy weather stations at different heights to monitor the meteorological conditions of the microenvironment of the Olympic Sports Center in real time. With the help of the latest intelligent observation results and intelligent meteorological observation equipment, the Asian Games meteorological monitoring has formed an intelligent and three-dimensional meteorological perception network.
