"Walking into Meteorological Experience and Wisdom" —— Four essays on the theme of World Meteorological Day

? Integrating meteorological experience and wisdom? Four papers on the theme of World Meteorological Day

0 1 changing with each passing day.

March 23rd is World Meteorological Day. At noon on March 2 1, the teacher led some fifth-grade students to visit xx Meteorological Bureau.

I will never forget the two hours I visited the Meteorological Bureau, because in these two short hours, I really felt how extensive my knowledge was and the infinite fun that technology brought us.

That morning, we went to xx Meteorological Bureau by bus, and there was a lot of traffic along the way. The students were in high spirits, talking and laughing on the road. The wild flowers on the roadside can't help but nod, as if they know that we are going to the meteorological bureau. Congratulations! The tree is also erect, showing a majestic look. Unconsciously, the xx Meteorological Bureau appeared before our eyes.

? Ah, here we are, here we are! ? We shouted excitedly. Walking into the Meteorological Bureau, a gentle breeze brushed my face, and I felt very comfortable. The fatigue along the way seemed to disappear in the clouds.

An uncle took us to the meteorological station and introduced us to meteorological instruments. The first thing that caught our eye was a big iron shelf. My uncle introduced us: "What's the name of this big iron shelf? Wind tower? From which direction the wind blows, the arrow will point in that direction, and we will know the direction of the wind. " The students listened and nodded again and again.

A classmate next to my uncle pointed to something that looked like a box and asked curiously, what is this? Uncle. ? Uncle smiled and said: It's called. Shutters? . ? I watched carefully. Shutters? It's like a small air conditioner. Uncle went on to say: blinds? The effect is great! It can prevent the direct radiation of the sun to the instrument and protect the instrument from the influence of wind, rain and snow. Besides, it has many vents, which can be properly ventilated and can accurately sense the changes of air temperature and humidity?

? Wow! ? The students shouted in surprise. It's not a box, it's just a box! ?

Later, my uncle gave us a detailed introduction of rainfall sensors, surface measuring instruments and other meteorological instruments.

This activity made me know some magical instruments, which opened my eyes, increased my knowledge, gained happiness and appreciated the infinite mystery of nature!

Students, do you know what day is March 23rd every year? Yes, today is World Meteorological Day. The day before yesterday, in order to let us know some scientific knowledge about meteorology, the school organized dozens of students from our school to visit the Municipal Meteorological Bureau under the guidance of teachers.

What did you see when you came to the Meteorological Bureau? Xx meteorological bureau? These big characters are very imposing. Walking into the gate, I was both nervous and excited. I'm nervous, afraid I'll be embarrassed when I'm asked questions in the future. I am very excited. This is my first time to the Meteorological Bureau. It was organized by the school, so I feel a little proud.

First of all, the uncles of the Meteorological Bureau took us to a survey site, divided them into two groups, patiently explained them to us, and some even drew pictures. I found that there are not only wind vanes and rain gauges that we are familiar with, but also shallow low-temperature sensors, heliometers and deep low-temperature sensors that we are not familiar with. Even the thermometers we are familiar with are divided into several types. That alone opened my eyes.

Then we came to the office building of the Meteorological Bureau. Graffiti cards with meteorological knowledge on both sides seemed to welcome us in the aisle. There are all kinds of scientific knowledge in Du Pai, and uncles will patiently explain it to us if some students don't understand it. Just give meteorological science this course? Live broadcast? Yes We also visited the office area, where it was so quiet that we could hear a pin drop.

Then we went to Huzhou Meteorological Exhibition Hall and learned about the history and honor of xx Meteorological Bureau. I even went to the conference hall and had a knowledge quiz with my uncles from the Meteorological Bureau. The atmosphere is very pleasant. But the most exciting thing is to record the weather forecast. Everyone watches the weather forecast every day, and may not know how it was recorded! . Two lucky students recorded a weather forecast under the demonstration of the host, which should feel very good. I found that the pictures we saw in the weather forecast were not there, but there was a green screen behind the host, and those pictures were post-processed. I used to feel proud to be a host. Just stand up and point to the picture and recite the lines. I didn't expect them to record with this skill of both mouth and hand. My respect for their dedicated work spirit arises spontaneously.

Finally, everyone took a group photo together and set foot on the return bus. During this visit to the Meteorological Bureau, I not only learned some meteorological equipment, but also learned a lot of meteorological knowledge, which really benefited me a lot!

Birds are singing and flowers are fragrant in spring. On March 2 1 day, under the leadership of the teacher, 60 students of our fifth grade got on the bus excitedly. We are going to the Municipal Meteorological Bureau to appreciate the charm of smart weather.

Sitting in the car, looking at the beautiful scenery outside the window, the car is driving on the wide road, the tall buildings are strewn at random, patches of green grass are rippling in the breeze, and a few small flowers are proudly holding their heads high, which is particularly eye-catching.

We arrived at the meteorological bureau soon. Led by an uncle, we crossed a small bridge and came to a meadow. I looked up and saw an arrow-like coordinate swaying in the wind. According to the description in the science book, I'm sure it is? Wind vane? . Look, it's still swaying in the wind. It is north today. Suddenly, a louver box in the middle of the lawn attracted us, and the students gathered in unison. My uncle introduced us. In this shutter, there are wet bulb thermometer, dry bulb thermometer, highest thermometer and lowest thermometer. ? The working principles of temperature and humidity sensor, heliograph, freezer, electric energy meter and precipitation weather phenomenon observation instrument are introduced in detail, and how to measure rainfall, temperature and humidity is explained in plain language. Students are eager to ask questions and have a strong interest in meteorological knowledge. We observe carefully. Although there are no desks and chairs, this does not reduce our thirst for knowledge at all. Some students squatted down and put the paper on their knees to record, some took the paper in their left hand and recorded it in their right hand, and some were more exciting. Putting paper on someone else's back to record is really different. It also restored students' thirst for scientific knowledge. If they don't understand, they will ask their uncle for help.

Following my uncle, we walked into the meteorological building, and various meteorological beauty were playing on the big screen. Smart weather? Eyes are more prominent. ? Wow! ? When the video shows strange weather phenomena around the world, the students can't help but exclaim. Often used in weather forecast? Light rain? 、? Moderate rain or heavy rain? The popular science exhibition hall is interpreting this knowledge: light rain precipitation is less than 10mm, moderate rain precipitation is 10 ~ 24.9 mm, heavy rain precipitation is 25 mm ~ 49.9 mm, heavy rain precipitation is 50 mm ~ 99.9 mm, and heavy rain precipitation is 100 mm ~ 25mm~49.9mm, which is extremely great. Also, the time points of words such as day, midnight, morning, around noon, afternoon and evening. It turns out that the weather forecast has such a wide range of knowledge that the uncles and aunts of the Meteorological Bureau are all versatile. I told myself to study hard. Then we went to the exhibition hall, and the students were full of praise for the development and achievements of the Meteorological Bureau.

What impressed me the most was the film and television center. It's surprisingly quiet here. My uncles and aunts all work hard. An uncle came out of a room with a green wall. We are curious. My uncle seemed to read our minds and said, this is the TV wall, and the weather forecast you see every day is here! ? I see, but we ask loudly: then why is it a green wall? Why are there no patterns on the wall? Uncle said: We took photos in it before adding images. ? I really admire the weatherman for pointing it out so accurately on the TV screen. My uncle gave us a chance, and two students showed it? Little forecaster? Elegant manners. In the meteorological knowledge prize-winning competition, students are eager to try, raise their hands and answer first.

We reluctantly left the meteorological bureau. You not only got a gift, but also brought back a wealth of meteorological knowledge. Through this activity, I was deeply moved and realized how shallow my meteorological knowledge is and how profound my wisdom is! This kind of activity is so meaningful.

Great, I was chosen to visit the Meteorological Bureau! It happened to rain lightly on the day we went. We took the bus and went to the destination xx Meteorological Bureau with excitement.

Hehe, the meteorological bureau is full of high-tech and developed working equipment and beautiful scenery. As soon as I entered the gate, the willow stood gracefully on both sides of the gate, like a spring girl combing her long green hair by the stream, which was very beautiful. Sixty of our friends, arranged in six rows orderly, followed the staff to the outdoor investigation site. Walking, we saw the unique scenery. The stream flows slowly and makes a clatter. The crisp and pleasant sound is like the wonderful piano sound, which makes people seem to have come to the world of music. There are many green plants on both sides of the stream, just like pieces of jade that are about to drip, flashing the light of nature before our eyes. We walked on the wooden bridge that perfectly matched the stream and came to the era of science and technology.

We saw many scientific instruments, which opened my eyes. The first stop is the artificial thermometer station. There are four thermometers in the louver, all of which are fixed at about.

1.5 meters. Looking up, there is the highest thermometer. You may think that the lowest thermometer is at the bottom, right? Oh, no, the lowest thermometer is almost parallel to the highest thermometer, but lower, like two good friends looking at each other. Dry and wet bulb thermometers lie like two sleeping beauties. Have fun! The next stop is the electronic thermometer. The electronic thermometer looks at the temperature through the thermal expansion and cold contraction of the electronic metal sheet. It gets longer when it is hot and shorter when it is cold. Electronic hygrometer is a machine with fluff inside. The higher the humidity in the air, the bigger the hair. On the contrary, the lower the humidity, the smaller the hair. These two stops are my favorite stops in the outdoor work area. There are many other stations, such as artificial rainfall counter station, rainfall sensor station and bare temperature station. Yes, there is another interesting station, which can fully reflect the enthusiasm of meteorologists. As soon as you enter the outdoor work area, you can see two anemometers, which are equipped with wind vane, wind cup and lightning rod respectively. An anemometer is no longer used. Although its scientific value has disappeared, it has become the home of birds and is still very valuable.

Entering the indoor work area, I not only saw a lot of weather forecasts about Huzhou, but also learned about meteorological measuring instruments. Fortunately, when the staff interacted with us, I also got a parasol, which was a prize I won by answering the question correctly. There are 10 good partners and compatriots with umbrellas in our class, and only Dr. Xiaozhuang and I have them, which makes me very proud. On the weather forecast screen, I saw that the air quality in Wuxing District was green, but there was a yellow warning or even a red warning in some places!

This activity, I saw a lot of meteorological instruments, meteorological early warning, but also learned a lot of meteorological knowledge. I said to myself, write it down! In this way, I wrote a travel note and a weather trip.

I meditated, wrote slowly, and recalled the experience of going to the Meteorological Bureau. Meteorology, these two words, are displayed in front of me again. I want to be a volunteer to protect the environment. Let's work together to protect the environment, paint the weather in Huzhou green, make the sky bluer, the air fresher and the home better.
