The weather is so charming composition

The weather is so beautiful

Date: March 9, 2012

Sunday morning , our whole family mobilized and visited the Kaihua County Meteorological Bureau.

As soon as we arrived at the door of the Meteorological Bureau, a burst of fresh air rushed towards us, making us feel refreshed immediately. Looking around, everything is green. Surrounded by green mountains, shaded by green trees, and the three characters "Weather Bureau" made up of red and green small trees intertwined... everything is refreshing.

Before we could take a closer look, an uncle named Zheng led us into the Meteorological Bureau building. After passing through the hall and turning around the corridor, we came to the ground meteorological observation field. What appeared in front of me were rows of "machines". They seemed to be soldiers on standby at any time, or like a group of mysterious detectives, standing quietly. What is this? What are they used for? Why is the meteorological observation field built here? Questions popped up in my mind like mushrooms after rain. Out of curiosity, I was ready to ask the question.

"There are eight important factors in observing meteorology. They are: temperature, precipitation, wind direction, wind speed, sunshine..." Unexpectedly, before I could ask, Uncle Zheng The conversation started.

"Look, these three are shutters." Uncle Zheng opened the middle shutter and said, "There are four thermometers here, this one is vertical. The thermometer is placed very carefully. It is about one and a half meters above the ground. It records the temperature felt by the human body. The two placed horizontally below record the highest and lowest temperatures of the day respectively. The one next to it is used to record humidity. You see, there is a gauze bag tied under it, which is used to sense the humidity of the air. These four thermometers are fully automatic instruments, and they can directly view the data through the computer. " As Uncle Zheng spoke, he took us to another shutter and continued to introduce: "There are two semi-automatic thermometers here." I followed Uncle Zheng's gestures and saw two strange machines: Chubby Dudu His body is wrapped in a layer of milky white paper material, and many faint horizontal and vertical stripes can be seen on it, as if he were a stocky young man wearing a fine plaid shirt. A thin wire is like a slender hand, drawing a zigzag, up and down purple line on the paper. "Is this also a temperature recorder?" I asked curiously. "Yes, our staff will conduct meteorological analysis based on the above data." Uncle Zheng said proudly.

Time flies. In the blink of an eye, various meteorological instruments such as temperature and humidity sensors, rainfall sensors, rain gauges, measuring evaporators, ground temperature meters, and heliographs, etc., In Uncle Zheng’s enthusiastic introduction, we became our friends one by one.

Uncle Zheng told us that in addition to ground meteorological observations, there are also low-altitude weather observations and high-altitude weather observations. () Our civilization currently does not have weather radar, so information in this area mainly relies on collecting data, sorting it out, and analyzing it. Uncle Zheng also took us to watch the weather cloud images sent by weather radars in surrounding areas, which was an eye-opener for me.

On the way home, I couldn't help but think about it: the unpredictable weather is like a naughty child hiding behind the gauze curtain, making people happy and worrying. And aren't all kinds of strange weather observation instruments and the rapid advancement of science and technology just like a magical big hand, helping us to lift the veil, understand it, study it, and explore the mysteries behind its various expressions?

"Ah, the weather is so beautiful! I also want to be a little weatherman.

"This wish was planted in my heart like a seed and began to take root...
