Will the weather forecast lie?

The weather forecast will not lie, it only represents the data detected by "national meteorological stations". Generally speaking, national meteorological stations will be built in areas with few buildings to avoid the influence of heat island effect and rain island effect. Big cities are generally built in suburbs, such as Wenjiang National Meteorological Observatory in Chengdu, Lianhuashan National Meteorological Observatory in Changsha, Baoshan National Meteorological Observatory in Shanghai and so on.
