Fuzhou meteorological department denied "compressing" high temperature data. Is there a conspiracy in the high temperature data?

Fuzhou meteorological department denied that there was a conspiracy. According to meteorologists, in the past, when measuring with traditional thermometers, it was necessary to copy the temperature manually. But now, the temperature is directly sensed by the sensor, and the data is automatically transmitted to the computer, with higher accuracy, and will be automatically uploaded to realize global enjoyment. Meteorological data of Fuzhou can be seen by meteorological agencies all over the country. "The accuracy of the weather forecast is strictly evaluated, and the deviation cannot be too big. As a meteorological department, we definitely want to be as accurate as possible, and there is no artificial' compression'.

Question 1: Why does the temperature forecast "fight"?

Careful citizens have found that the weather forecast data in Fuzhou is also different from that of Fuzhou Meteorological Observatory.

According to meteorologists, according to the internal process of the meteorological department, the data of weather forecast is produced by the local meteorological station and sent to the meteorological department at the next higher level. There's actually only one version.

For example, the weather forecast of Fuzhou is made by Fuzhou Meteorological Observatory and then sent to the Central Meteorological Observatory. Therefore, if it is the weather forecast at the same time, it must be the same. However, TV, Internet, radio and other media release forecasts often lag behind and the time is not uniform, so there will be differences. As for some mobile phone software for forecasting the weather, it is more difficult to ensure that the data is updated in time because of irregular management.

Question 2: What is the difference between the predicted temperature and the actual temperature?

According to meteorologists, every weather forecast requires cooperation of many people, comprehensive analysis of multiple data and icons, and then consultation with national and municipal meteorological stations and internal personnel. For example, with the recent high temperature in southern China, it is particularly necessary to analyze the intensity, size and control area changes of subtropical high, and also refer to the live data monitored by ground observation fields.

However, even so, the weather forecast cannot be 100% accurate. After all, there are too many factors that affect the weather. Even small changes in wind, wind direction and wind speed will affect the temperature trend. "The actual temperature in Fuzhou two days ago was lower than the predicted temperature, which has a lot to do with the sea breeze."

Question 3: Will the high temperature data be "suppressed"?

These days, when Hangzhou and Shanghai broke through 40℃ easily, Fuzhou was also extremely hot, but it never reached 40℃. Many citizens have suggested that this is not consistent with the heat they feel. Are these high temperature data distorted and artificially depressed?

According to meteorologists, in the past, when measuring with traditional thermometers, it was necessary to copy the temperature manually. But now, the temperature is directly sensed by the sensor, and the data is automatically transmitted to the computer, with higher accuracy, and will be automatically uploaded to realize global enjoyment. Meteorological data of Fuzhou can be seen by meteorological agencies all over the country. "The accuracy of the weather forecast is strictly evaluated, and the deviation cannot be too big. As a meteorological department, we definitely hope to be as accurate as possible, and there is no artificial' compression'. "

Question 4: Why is the data far from the somatosensory feeling?

In this regard, meteorologists explained that the temperature in Fuzhou is the temperature in the louver box on the Wushan observation field. The shutter box has high requirements for setting and good ventilation conditions. From the ground 1.5 meters, the grass under the louver should not exceed 20 cm, which is unified throughout the country. The temperature measured in this way is the closest to the natural real temperature.

When citizens live in cities, the heat island effect is strong and the human body feels hotter.

Question 5: Does Fujian really not exceed 40℃ this year?

At present, Fujian and Jiangsu and Zhejiang provinces are controlled by subtropical high, and the temperature in Fujian is slightly "low-key", mainly due to the high forest coverage rate in our province. Compared with Jiangsu and Zhejiang, Fujian's urban construction scale is not so huge, so the heat island effect is relatively weak.

In addition, since July, the high temperature has continued in Jiangsu and Zhejiang provinces, and the heat has not been exchanged in time. It is difficult for the minimum temperature to drop below 30℃ at night, and the temperature rises faster when heating during the day. However, Fuzhou has never had a record of the lowest temperature exceeding 30℃ at night.

In addition, the statistics of the Provincial Meteorological Observatory show that the temperature in Fuzhou has only exceeded 40℃ twice since 1953, and there has been no high temperature above 40℃ in Fujian this year.

Question 6: Did the two subtropical highs work together to cause the high temperature in the south?

In the past few days, there has been a high-temperature "frenzy" in Jiangsu and Zhejiang provinces, and many historical high-temperature records have been rewritten. In this regard, some meteorologists have analyzed that this is a merger of the Pacific subtropical high and the Arabian subtropical high.

In this regard, climate experts in our province said that there is no such statement. The Arabian subtropical high is mainly controlled in West Asia, and the recent high temperature in the south is mainly affected by the Pacific subtropical high. This year, the Pacific subtropical high controlled Jiangsu and Zhejiang earlier and stronger than normal, which is why it is so hot. Experts also said that even if the two subtropical high merge, the temperature may not be higher.
