The composition of visiting the meteorological bureau is urgent! (More than 600 words! )

It's sunny and sunny today. The school organized all teachers and students to practice activities together, and went to the Meteorological Bureau in the fourth grade. Hearing this news, we jumped three feet high happily and finally got the meteorological knowledge we wanted to know about Songyang.

Along the way, flowers smiled at us, birds greeted us, trees waved to us, and soon we arrived at the Meteorological Bureau. The uncle there enthusiastically introduced us to the use of various meteorological equipment.

As we stood in an empty place and couldn't hear my uncle's introduction clearly, we lined up in turn to enter the observation site and had close contact with various meteorological equipment.

As soon as you enter the small door, go straight to the most striking wind tower. There are five or six students there. They are full of curiosity. Touch this, look at that and have a chat. The weather vane said in science class before that it was the first time to see the real thing. You see, this guy is like a benchmark and ugly. Who knew he could accurately measure the wind direction? The wind cup above is very small, like three small spoons. It is used to measure wind speed. The stronger the wind, the faster the wind cup turns.

You see, those three ivory louvers are lined up like soldiers waiting for inspection. Let's take a look at the first shutter next to it, which has a manual measuring instrument. This little thing can draw the changes of temperature and humidity in a day. Then we came to the second shutter box. The teacher opened the shutter box and saw a small thing like a stick inside. Don't underestimate it, it is the most advanced weather monitoring equipment in the world at present, and it can transmit every minute of data to the indoor computer in time. By combining computer with human brain analysis, we can understand today's weather. Then we came to the third shutter. There are four thermometers in it. It seems that they are similar to thermometers In fact, they can measure the highest and lowest temperatures in Songyang all day.

Others include heliograph, rain gauge, visibility meter, and the most striking thing is solar charging board, which provides power for this visibility meter. While we were happy, we even stepped on a thermometer to measure the different depths of the surface and underground!

Uncle also said that these meteorological monitoring devices can provide a lot of convenience for people's agricultural production and life!

During this trip to the Meteorological Bureau, we not only learned about the use of meteorological equipment, but also learned a lot of astronomical knowledge, which really benefited a lot!
