Composition of qianxi county No.3 Primary School Visiting Meteorological Observatory 100 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 to know the meteorological knowledge of Songyang.

Along the way, flowers smiled at us, birds greeted us and trees waved to us. Soon, we arrived at the Meteorological Bureau. My uncle 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 we entered the small door, we went straight to the most eye-catching wind tower. There are five or six students there. They are full of curiosity. They touch this, look at that, and talk about something. 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 knows that he can accurately measure the wind direction. The wind cup above is very small, like three small spoons.

You see, three ivory louver boxes are lined up like soldiers waiting in line for inspection. Let's first come to the first louver next to it, which has a manual measuring instrument that can draw the changes of different temperatures and humidity in a day. Then we came to the second shutter box, and the teacher opened it. There was a stick-shaped thing inside. Don't underestimate it, it is the most advanced meteorological monitoring equipment in the world at present. 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 come to the third shutter, which contains four temperature measuring tubes. 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 one is the solar charging board, which provides power for this visibility meter. While we are happy, we even step 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!
