With the strengthening of the subtropical high pressure, from the 4th to the end of this week, northwest China, North China, Huang Huai and Jianghuai, Jiangnan and other places, will have a wide range of high temperature weather.
The highest temperature in Shanghai Xujiahui station today shot up to 40.2℃. Some netizens found that the weather software that comes with Apple iPhone shows that the maximum temperature in Shanghai today is as high as 50℃, such as 51℃ in Putuo District and 47℃ in Jing’an District.
In this regard, the Shanghai Meteorological Bureau official microblogging @shanghaiweather responded to some users’ feedback that “the highest temperature in Shanghai Putuo District is 49℃”: the temperature data provided in our service is the background temperature of the atmosphere measured by standard meteorological observation stations according to the unified technical standards, while some cell phone software comes with the weather App does not use the actual observation data, but uses other Some mobile phone apps do not use actual observation data, but use other data and means of estimation. In short, we have the actual observation point data, they don’t!
It is said that the weather forecast in the Apple iPhone system is the data provided by TWC (The Weather Company) in the United States, and the actual temperature based on geographical location is estimated by other means, and does not represent the real data.
In meteorology, the so-called surface air temperature is the air temperature observed at 1.25 meters to 2 meters above the ground (1.5 meters in France). Ground-level meteorological observations are the oldest and classic method of atmospheric analysis. Surface meteorological observations allow to obtain some direct physical quantities, such as air temperature, air pressure, wind speed and direction, precipitation, etc.
