Why is there a rumor on the Internet that the Meteorological Bureau dare not report it when it exceeds 40℃?
According to the China Meteorological Bureau, according to the regulations of the World Meteorological Organization, the temperature released by the meteorological department is the temperature measured by the thermometer in the louver. The louver box must be located on the lawn, 5 meters away from the ground 1.5 meters, and the surrounding area is relatively open, without tall buildings and trees. Keep out the wind or sunlight.
In the same city, the temperature of louver is different from that of cement road and asphalt road. In the case of strong sunshine, the temperature at the height of cement road and asphalt road 1.5m may be 4℃ to 5℃ higher than that measured by the louver.
In addition, everyone's somatosensory temperature is different. Somatosensory temperature refers to the temperature at which the human body feels the air, which is different from the temperature of the actual environment. At present, considering the influence of wind and air humidity on human body, the Meteorological Observatory publishes dressing index, air conditioning index, sun protection index and other life meteorological indexes to make up for the shortage of simply forecasting temperature.
So, is there really a situation in which forecasters deliberately underreport?
According to China Meteorological Bureau, the temperature forecast is uncertain, and a certain range of errors is inevitable. Nevertheless, the meteorological department still has strict inspection and assessment standards for forecasters. For example, if the difference between the predicted temperature and the actual temperature is more than 2℃, it is considered that the prediction is inaccurate. Therefore, the statement that forecasters deliberately "understate the high temperature" does not exist.
