"The weather forecast is 36 ° C, why do I always feel more than 40 ° C?" The national weather observation station meteorological expert interpreted this way

The Yangtze River Daily Da Wuhan Client July 22 (Reporter Wang Huichun Correspondent Chen Shengchao) "It is too hot, it is hot." Recently, citizens are always wondering that the temperature of the outdoor body has exceeded 40 ° C, but the weather forecast is only 36 ° C. How is the temperature measured? On the morning of the 22nd, a reporter from the Yangtze River Daily visited the Wuhan National Basic Meteorological Observation Station located in Cihui Street, West Lake District.

A few days ago, Wuhan ushered in a wave of precipitation, the temperature dropped slightly, and returned to the high temperature line of 35 ° C. On the 22nd, the temperature rose again. When the reporter arrived at the West Lake National Station, it was 10:30 in the morning. Standing outdoors felt the sun was hot. The highest temperature on the day of the forecast of the Wuhan Meteorological Bureau was 36 ° C.

The meteorological observation site is outdoors at the national station, and a large variety of observation equipment is placed in an orderly manner on the large lawns. In exchange, "the elements of observation include temperature, air pressure, humidity, wind direction, wind speed, precipitation, lightning, light ground temperature, deep ground temperature, sunlight, etc.". "

Data such as deep ground temperature are too professional. The temperature data that citizens are most concerned about comes from the shutters that measure the temperature. The louver is about 1.5 meters away from the ground. It is ventilated on all sides. Opening the door of the box, there is a circle of probe hanging in the air. It is understood that this is a sensor that automatically measures temperature and humidity. Why can't you see the temperature? "The observation station is now automatic." Wuhan Meteorological Observatory's chief forecasman said that the old -fashioned thermometer was indeed hung in the louver in the early years. Automatically upload background. "

The prediction is the standard value that is not disturbed

The reporter saw on the computer terminal of the national station that the temperature data of the shutters on the ground comprehensive observation business software was 34.5 ° C, but the temperature of the outdoor body was significantly higher than that? "This is also the question of many citizens." Wei Wei explained that in accordance with the unified standards of the World Meteorological Organization, the temperature refers to the standard air temperature that is not disturbed. "Skin temperature, surface temperature ... are not the temperature that the meteorological department is usually forecast."

Therefore, the setting of the shutters is also particular about: 1.5 meters high, keeping ventilation, and the surrounding are relatively open and unstoppable. Avoid direct sunlight and sunlight reflection, so as to get representative temperatures. The temperature observed in the louver box is 36 ° C, the cement pavement is 48 ° C, and the temperature difference of more than 10 degrees, and it is only 35 ° C on the lawn. "

This is also because the basic meteorological observation stations in Wuhan City are in Yuancheng District. "The construction station has requirements for the surrounding environment and the height of the building. The observation field must be an empty place. We chose to be in the place of Cihui. The construction of the area of ​​the regional automatic station requires a little bit lower, and it also needs an empty venue of 4 meters × 4 meters. There are more than 200 areas in our city with automatic stations, which are evenly distributed. The central urban area is about 5 kilometers. "The temperature in the temperature that we predicts every day will be slightly higher than 1 ° C. hot".

Weather forecast is a forecast science

The basic meteorological observation station in Wuhan is basically no one. "At present, the only personnel need to be high -altitude class. Put the empty hydrogen balloon every day and make high -altitude observations to achieve the collection and observation of high -altitude weather data. If you need someone to do it, the other work is automatic observation. "

As the chief forecaster of the Wuhan Meteorological Bureau, Wu Wei's main battlefield is in the Wuhan Meteorological Bureau on the West Lake Lake Ring Road. Enter the model for weather prediction. " There are some weather proverbs in the folk, such as "Chaoxia does not go out, and the sunset is thousands of miles". Wu Wei said that this kind of folk wisdom can only speculate in the short time weather and cannot meet the refined standards. A forecast science. " Links >>>

Tomorrow Summer Weekend Weekend must prevent strong convection

Tomorrow (23rd) welcoming the hot summer soil, the last solar term in summer.

The heat of the heat is hotter than Xiaoshu. It is the most violent and hottest season of the sun in the year. The climate of the summer summer is high temperature and heat, thunderstorms, and typhoon frequent.

It is said that it is more hot, but according to scientific predictions, two days after the Ming Dynasty, due to the influence of high -altitude and low tanks and low -level layers, the city will have precipitation, and the temperature will fall slightly and return to the high temperature line. From the 25th, under the control of the auxiliary high, there will be a period of sunny and hot weather in our city. Tomorrow to the day after night, with the rain, the city may be accompanied by thunderstorms, short -term heavy precipitation and other strong convective weather. Everyone should pay attention to preventive measures.
