Visiting Meteorological Bureau: My Mood Composition

I will never forget the half-day I visited the Meteorological Bureau, because in this short half-day, I really felt how broad my knowledge is and the endless fun brought by science and technology! That afternoon, we walked to Yangzhong Meteorological Bureau, and the scenery was beautiful all the way. The students were in high spirits on the road, talking and laughing, and the grass on the roadside kept nodding, as if to congratulate us on knowing that we had gone to the Meteorological Bureau! The tree stands erect, showing its majestic appearance. Even the river is crystal clear, and the fish in the river are constantly playing, which is so uncomfortable!

Unconsciously, Yangzhong Meteorological Bureau appeared before our eyes. So Mr. Chen of the brigade invited Uncle Leng from the Meteorological Bureau to explain the knowledge of meteorological instruments to us. Uncle Leng took us to the place where we put the instruments. First, he explained the shutter box. He said, "The louver is a protective device for measuring temperature and temperature instruments. There are two kinds of instruments in it, one is a thermometer and the other is a hair hygrometer. " So Uncle Leng opened the shutter box, only to find that the contents were varied and looked like high technology. Take the hair hygrometer as an example. The temperature is mainly measured by the female hair of a minor (15~ 18 years old), because the female hair is more sensitive and the measured temperature is more accurate. Speaking of which, it reminds me of the thick fog and haze that enveloped the whole city a few days ago. Uncle Leng replied: "This is because there are two possibilities. The first is automobile exhaust emissions, and the second is that farmers burn straw seriously. " Oh, I see. Then Uncle Leng introduced the measuring cylinder, which was used to measure the degree of rain. There is a funnel-shaped reservoir in the middle, and there is a ruler of several millimeters outside the measuring cylinder, so that when it rains, the rain drops down along the funnel-shaped reservoir. On the second day, the staff can accurately measure the degree of rain as long as they watch the rainfall reach several millimeters. Finally, Uncle Leng introduced the evaporating dish and the sunshine meter to us in turn. . .

At this point, we visited the staff's studio again, which really opened my eyes! Then we say goodbye to the staff.

Although the visit of the Meteorological Bureau is over, I will never forget it! Also let us benefit a lot, we must redouble our efforts in future study!
