The body temperature and forecast temperature can be different from 5 ° C. Ningbo weather experts interpret this

After the heat, the high temperature of the sun continued. On July 25, the weather forecast showed that the highest temperature in Ningbo City was around 35 ° C. Some citizens use the temperature measurement to measure the temperature of the outdoor body, with a value of 40 ° C, which is much higher than the temperature of the meteorological station forecast.

Why do citizens have different sensing temperature and temperature in the outdoor body? On July 25, the reporter consulted the staff of the basic meteorological station of Ningbo Langzhou National Weather Station with questions.

At 2 pm on the same day, the reporter came to the observation site in the Meteorological Bureau of Lizhou District. On the lawn of nearly 2,000 square meters, various observation equipment was discharged in order. Each device had specific observation functions. "These devices automatically collect meteorological observation data for 24 hours. Observation elements include more than 20 items such as air temperature, ground temperature, grass temperature, humidity, wind direction, and wind speed."

The temperature data that citizens are most concerned about comes from the shutters that measure the temperature. "According to the unified standards of the World Meteorological Organization, the temperature meter of the meteorological department should be placed in the shutters, 1.5 meters high from the ground, and the shutters should be placed on the empty lawn." Wang Jie introduced that the fuse of the crossbar is a glass reinforced reinforcement. It is made into a shutter -like window, preventing direct sunlight, windproof, rainproof, ventilation, air circulation, and thermometer is placed in it.

Blossom boxes that measure temperature

Open the door of the box, hanging the probe in the air, but the data of the displaying temperature is not seen. "The data collected in the louver box will be transmitted to the background through the sensor and transmitted once a minute. After three real -time temperatures take the average calculation value, the final temperature can be determined." Wang Jie said.

Data detection of various equipment detection of the computer on the computer side

On the computer terminal of the meteorological station, the reporter saw that the data that was automatically uploaded to the ground comprehensive observation business software was 35.9 ° C. At the same time, the data transmitted by the ground temperature detector was 48 ° C, and the grass surface temperature was 44.2 ° C. "The temperature displayed by the weather forecast refers to the standard air temperature that is not interfered. The temperature of the somatosensory temperature is not the temperature of the meteorological department's usual forecast."

Wang Jie introduced that even under the same temperature conditions, people will have different feelings due to the comprehensive effects of air humidity, wind speed, sunlight irradiation, and even the quality of the mood. For example, under the same temperature conditions, if the relative humidity is relatively large and the wind speed is relatively small, people will feel sultry, and people with weak constitution will even have symptoms of heat stroke.

"The temperature of meteorological forecast is just a reference. Those who have been engaged in high -temperature operations for a long time should be alert to the hidden heat stroke hazards that may bring in the heat stroke due to local high temperature and their physical condition." Wang Jie reminded.
