Yuncheng Salt Insurance Center launched the Salt Lake Water System Survey on the 318th day

In order to better understand the impact of regional climate on the salt pond in Yuncheng and understand the important role of meteorological monitoring on the protection of salt ponds, under the leadership of Lu Guoyu, director of the central office, the research team came to the Meteorological Bureau of Yanhu District. Li Yan, deputy director of the bureau, conducted a detailed introduction and guided everyone to investigate some meteorological observation sites in the urban area.

According to reports, the Meteorological Observation Station set in the Yanhu District Meteorological Bureau belongs to the national basic meteorological station, covering an area of ​​23 acres, and the observation elements are relatively complete. There are many weather elements such as temperature, deep ground temperature, shallow ground temperature, sunlight and so on. These data are transmitted in real time, and all data need to be updated and uploaded every minute.

Temperature, humidity, air pressure, precipitation, evaporation ... In front of the computer monitor of the East Garden Meteorological Observation Station (Basic Station), we see dense real -time observation data on the screen.

Li Yan said that the observation data will be updated every minute, and when it changes from blue to green, it proves the "message" (including all observation data). "The papers are like the secrets sent by the reporting aircraft in the war, but the electrical text here is about meteorological. You see, it is clear that it can be seen that yesterday's 24 -hour precipitation was 13.5 mm."

According to reports, all the data here have special computers for backup. Observation objects at the observation station are all instruments in the meteorological observation field.

Meteorological observation field

Meteorological observation field, as the name suggests, is a venue for installing meteorological instruments for ground meteorological observation. In the observation field in the East Garden Meteorological Observation Station, the standard area is 25 meters by 25 meters, and there are more than 20 equipment in it.

Meteorological observation field

We saw at this meteorological observation field that above a high platform, various instruments with various shapes were distributed in an orderly manner, including precipitation phenomena, weather phenomenon video intelligent observations, automatic meteorological stations, etc. Specific observation goals.

On a sign at the entrance of the observation site, the blue -bottomed white word reads several large characters "Salt Lake National Basic Meteorological Station". Li Yan said that in fact, there was a record of meteorological data as early as 1954 in the salt lake area. It is said that the observation point is on a farm.

Judging from the observation of the Donghuayuan site, as of now, the highest temperature in this area this year is 39.9 ° C (the temperature in the area of ​​the East Garden is lower than that of the urban area).

Under the guidance of Li Yan, we learned about the operation methods of the observation field equipment one by one, and felt the advanced level of meteorological automation observation:

Fighting rainfall sensor

The rainfall barrel is used to collect rainwater, which is 70cm from the ground. Earlier, a scaling cup must be placed next to the rainfall barrel during artificial measurement, and now it is fully automatic. Today, this artificial rainfall barrel is the main function of the snowfall in winter.

The visibility instrument, as the name suggests, is used to observe visibility, and visibility is the longest distance that can be seen at the horizontal position.

DSG1 precipitation phenomenon

The precipitation phenomenon instrument is used to observe the precipitation phenomenon such as rain, snow, hairy rain, and rain. The lens of this instrument is very intelligent.

Weather phenomenon video intelligent observation

The video intelligent instrument observes weather phenomena, including dew, frost, icing, etc. There is a fish eye on the round lens.

Instrument dedicated to measuring the icing of the wires

Measure the instrument of snow depth

Weighing snowfall (specifically used to measure winter snowfall, use it in summer to back up measurement of rainfall)

In addition, there are many observation elements here, some are used to measure the freezing situation (there are also measuring the icing of the wire), and some of which measure the snow depth. Among them, weighing snowfallers are specifically used to measure snowfall in winter, but in summer, it is used to back up to measure the rainfall.

According to reports, for the accuracy of the data, some observation instruments are set up at the same time, and then the average value of the observation data is taken.

Instruments with thickness of frozen soil (soil under the ground can frozen) thickness)

For the situation of the land, there are detailed measurement in the observation field.

For example, measuring frozen soil (how deep the soil can be frozen under the ground) is of great value for agricultural production and construction projects.

The frozen soil manually needs to be irrigated in a rubber tube of about 1.5 meters in length, and then put it into the land for measurement.

Sensor that measures grass temperature

For another example, measuring deep ground temperature, four tubes with different lengths need to be used (40cm, 80cm, 160cm, and 320cm) to measure the temperature under different depths. The shallow floor temperature instrument is arranged in a 2 meter width and 4 -meter -long ground temperature field, which measures the ground temperature of the ground temperature, 5cm, 10cm, 15cm, and 20cm. In addition, there is a sensor that measures grass temperature next to it, with 20cm from the ground.

"Spiders need to pay special attention to our daily protection, because the spider's net is most likely to block the rainfall barrel, so sometimes we put some wind oil essence and camphor pills ..." Li Yan said.

Wind tower with wind direction and wind speed

The tall long rod is a wind tower, which is specifically measured by the wind. The top is like a air vane to measure the wind direction; the wind cup is used to measure the wind speed.

Automatic weather station

Li Yan said that since 2003, the automatic station has been opened, and there have been many years of manual observation data comparison. The observation room of gas -soluble gum (the content of PM2.5 and PM10 in the atmosphere)

The left side of the computer is PM2.5, and the right side is PM10

Observation data curve change diagram

Entering the observation room of the gas solution (the content of PM2.5 and PM10 in the atmosphere), we immediately felt the coolness inside, which was a special requirement for room temperature. The left side of the computer is PM2.5, and the PM10 is displayed on the right. After some operations, the observation data curve changes in a certain period of time came out.

Instrument on the roof of the gas solution observation room

The instrument is on the roof. It is connected to the computer with a dedicated paper belt (filter paper) with an oval shape surrounded by a small point. The deeper proof of pollution is more serious. Through the computer, we can understand the specific values ​​of real -time air quality -PM2.5 and PM10.

For some visit, we have a deep understanding of the meteorological observation field. As a "onlooker", it kept closely examining the weather conditions here. So, what are the effects of meteorological observation on the protection of salt ponds? We will focus on the next issue.
