Snowfall consists of a large number of snow crystals of different sizes, and generally there are many smaller ones. In order to describe the particle size distribution characteristics of falling snow crystal population, snow crystal spectrum or solution spectrum after snow crystal melting is often used.
Snow crystals are mainly increased by condensation in clouds. First of all, ice crystals are produced by ice nucleation in cold clouds. They grow into snow crystals through condensation (ice crystal process), and then they can grow by colliding with supercooled water droplets.
Snowflakes are mostly hexagonal, and there are so many patterns because the molecules of ice are mostly hexagonal. For hexagonal flake ice crystals, the curvatures of their surfaces, edges and corners are different.

3. A story about ice and snow, winter is a silent season. Grandpa always sits alone on the wall in winter, silent. The sun caressed his face as old as a walnut with gentle hands, and caressed his beloved child like a kind mother. Winter is the season of falling snow, and snowflakes are like mysterious white butterflies. My grandfather told the story of his childhood on a quiet snowy night. He is as happy as a child's heart. It is full of infinite warmth, just as we suddenly think of the spring outing on a sad day. In fact, no one knows what Grandpa is thinking in winter, but his story tells me that he has been far away from his childhood and hometown. The characters in ................................................................................................................'s plays are also reminiscent of the long loofah figure under the vine. The dozing old man forgot to set up a sentry in the sun. At this moment, you dive into the inland river to catch the sadness on the beating waves. My riverbed is dry and cracked, and it goes deep into the blood of his ancestors. The bell rang, and the dew rolled in the morning was playing. In fact, the lotus leaf is fresh and stretches in the wind. Actually, winter is beautiful. Nature takes off her coat and reveals her naked soul. You can listen to the sound of jointing in early spring. —————————————— Lin Jian published Silent Winter on July 9, 2006 10: 18: 24 Winter is as cold as a patient who has lost his memory.
Still cold, quiet and expressionless, winter is as pure as a white swan in the online game world. Its carefree and wild nature makes sparrows start from dead branches and get into warm clothes. Cold loneliness is another landscape of life. Fortunately, in such a calm season, the wind is full of homesickness and tears begin to crystallize. Winter always reminds people of something, or misses something. The fire is burning, and I always think I can burn out some past events.
Many things need us to warm up. Actually, love and life will calm down day by day. Winter is a snowflake. Let me learn to be grateful.
Thank the breeze for bringing me another kind of beauty in life and gently awakening my sleeping soul. February 3, 2005 ———————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————— Past eyes can't sweep away inner emptiness and anxiety. In the storm, they are getting old and the most corrupt. There is no need to talk about health and achievement. Perhaps it is such a corner, you think it is bright and dazzling, stubborn and contrary to the season, but it still ignites your inner weakness and hopes that you will be strong and as ordinary as a piece of paper flying in front of you. Maybe it doesn't mean anything, but it shows a kind of depression at most. The sight of the countryside can give life and hope to many people —————————————————————————————— The Trak snowflake outside the window is ringing the bell of evening prayer, and the room is getting ready. People wandering around the dining table are preparing a sumptuous feast. From the dark road to the gate, only a few trees are shining with golden light, sucking the cold dew in the soil, and the wanderer has quietly stepped into pain. The threshold has turned to stone. Under the bright light, there are bread and wine on the table ——————————————————————————— Tang I love winter, and that six-petal snowflake is a gift from my grandpa in winter. I love winter. The snowman made by children is the joy brought by Santa Claus. I love winter, and the snowy world is a playground for children. I love winter. Colorful cotton-padded jackets add color to the snowy world. I love winter, that white and flawless winter! ———————————————————————— The first rain in winter gently weaves a picture of a water town in the south of the Yangtze River. A wet poem has disappeared from the bridge in the season, but the misty winter rain still has the beautiful charm of autumn, weaving a gorgeous and dense piece. The misty rain and fog have blurred the mirror, and the moonlight song has penetrated into the spotless green space in the dream. Although the season gradually becomes desolate, depressed and decadent, it is accompanied by the north wind. However, I read a fresh Preface to Winter from this cool winter rain. Supplementary answer: "Qiu Meng" Dai Wangshu's "The Shepherd's Bell" shakes off the light leaves. Qiu Meng is faint, which is the gentle and graceful love of shepherdess.
So my dream came quietly, but it carried a heavy past. Oh, now, I'm a little cold, a little cold and a little depressed.
(193 1 year 1 month) Flowers in first frost Dai Wangshu Flowers in first frost in September, Flowers in first frost in October, Misty Girls Come to My Bones. Decorate you with autumn leaves, decorate charming girls with monotonous death and fog, and send me your plain flowers.
Do you still have tears of pearls? The sun has not been rekindled. I watched my sideburns fall, so I ushered in the autumn decorated by you.
"Autumn" Du even sounded like a mature pigeon whistle, and the noisy summer with showers has passed. No longer think about the severe and sultry test and the detailed memory of dangerous swimming.
After breaking ground in spring buds, twisting and injury in the growth of young buds, these branches are also crazy in the hot sun and almost lost their way in the rainy night. Now, the plain sky is cloudless, the mountains and rivers are clear and clean, and the vision is particularly broad; In the season of wisdom and emotional maturity, the river seems to come from a deeper source.
Turbulent airflow ferments in the valley to form transparent good wine; What autumn is blowing? The intoxicating fragrance has deeply dyed the autumn flowers and leaves. Street trees also imply something in red, and the wheels of bicycles are shining with vitality; The long arm of the tower crane points to the distance at high altitude, and Qiuyang scans the harvest information on it.
"Grass in the South of the Yangtze River" In the autumn when chrysanthemums are in full bloom in Li Ji, I came to Jiangnan for the first time. Although I came in a hurry and went in a hurry, your beauty is beyond my imagination by a thousand times.
Looking at your beautiful city, all the most beautiful pictures are lost.
