Last year, our school set up a red scarf weather station, and all the students signed up for it. I was lucky to be admitted. The establishment of this red scarf weather station in the school can not only cultivate students' comprehensive ability, but also cultivate students' good habit of doing things carefully. With this weather station, we small meteorological enthusiasts are not afraid of wind and rain, cold and heat, go to school on time, learn meteorological knowledge together, observe weather changes and record meteorological data.

As soon as I entered the school gate, the most striking thing was a box on a high shelf, all white and very cute. The teacher told me that this is a special box for measuring air temperature and humidity, called the louver box. On the metal shelf in the shutter, two mercury thermometers with the same shape and size are usually used. They are like twin brothers. One is placed in the east of the bracket to measure the air temperature, which is called a dry bulb thermometer, and the other is placed in the west of the bracket. The ball of a watch is wrapped with gauze 10 cm long, and the other end of the gauze should be immersed in a water cup. This is called a wet bulb thermometer.

The hour hand of the watch points to eight o'clock. My partner and I are going to conduct a weather observation. We opened the shutter box, and the teacher told us that each compartment of dry and wet balls was 02 degrees. I did as the teacher said, and I got accurate data as expected. Next, it depends on the humidity of hair. Hair is made of human hair (or cow casing), because these hairs have such a characteristic: they stretch when the air is wet and shorten when the air is dry. These are what the teacher told us. It's time to observe the wind speed and direction. I turned on the wind direction and wind speed switch of the indicator and observed the average position of the wind speed pointer swinging for two minutes. When the wind speed is low, turn the wind speed switch to "20" and read the scale scale of 0-20 m/s; When the wind speed is high, turn the wind speed switch to "40" and read the scale of 0-40m/s ... The direction should also be observed the most in two minutes. If there is no wind, the wind vane does not rotate, the wind speed is 0 and the direction is 0. The clouds in the sky are ever-changing. According to the height of the cloud, it can be divided into three categories: high, medium and low. According to the shapes of clouds, there are nimbostratus, stratocumulus, broken rain clouds and cumulus clouds ... You must be very careful when observing clouds to ensure accuracy. This observation was the one that impressed me the most, because I learned how to observe the weather that day. Studying meteorology means you make a new friend and occasionally guess what God thinks. We record data in a notebook. Every day, we publish the weather forecast on the school website. Every day, a large number of meteorological enthusiasts open our school's website to watch the weather forecast and leave messages on the message bar of the red scarf weather station. It says: Thank you very much. Because your school has a red scarf weather station, it has provided us with a more accurate weather forecast. We don't have to wait in front of the TV on time. We can open the website of your school to watch the weather forecast at any time, which makes me feel good about the weather. Now I watch the weather forecast on your school website every day and tell my relatives and friends the good news so that they can enjoy the convenience together.

The following can let you know the importance of observing the weather. Before I took part in the weather observation. Once, my mother and I went to my grandmother's house to visit her. It was sunny and sunny before we went to grandma's house. The dark blue sky is as blue as washing, the sun shines warmly and the breeze blows gently. But on the way, the sky suddenly turned from sunny to cloudy, and the rainstorm suddenly poured down like a waterfall. My mother and I ran as fast as we could. Although we were out of breath, we were finally "soaked". Hey! It's really "something unexpected happens in the sky." Since I became an observer at the red scarf weather station in my school, I have the ability to know the weather by looking at the clouds.

Dear students, it is really a good thing to learn some meteorological knowledge, which can make you have the function of predicting the future. If you are also interested in meteorological observation, welcome to our red scarf weather station!
