Why doesn't the weather forecast in Chengdu write 40 degrees?

First, why is it rarely reported as 40 degrees? Maybe the temperature in your place really seldom reaches 40 degrees. Second, the temperature varies from place to place, the environment is different, and the somatosensory temperature difference is also great. For example, if you are in a car, you can reach 50 or 60 degrees in ten minutes. You are standing by the lake, you are standing on the road, and you are standing on the top of the mountain. The temperature you feel is different. The temperature you feel is not the most authentic, accurate and representative atmospheric temperature in your area. Third, all meteorological data observation instruments, methods and time are unified, and the observation site will be chosen to best reflect the characteristics of local large-scale meteorological elements, and the surrounding area must be empty, without roads, rivers and large buildings. The temperature sensing point must be in the louver box of 1.5m, and the temperature measured by the Meteorological Bureau is measured in such an environment. When we look at the weather forecast, a city or a county often gives only one temperature forecast value, but the area of a county and city is very large, and the temperature varies from place to place, which requires us to give a representative temperature, that is to say, the temperature of this weather station can be used to represent the situation of the whole city. So, has the Meteorological Bureau ever predicted the high temperature above 40 degrees? In the national high temperature warning list of the past few years, it is found that in addition to Xinjiang, in Henan on June 4, 2020, and in recent two years, Chongqing often forecasts the weather above 40 degrees for several days in July and August every year.
