(a) Why do frosts in China mostly occur on clear nights?
In China's four seasons in the mid-latitudes, late fall to the next year's early spring season, just before the beginning of winter and after the end of the time, the temperature at night can generally be reduced by less than 0 ℃. In the clear night, because there is no cloud, the ground heat is emitted very quickly, in the first half of the night due to the ground during the day to store more heat, the temperature is generally not easy to drop to below 0 ℃. Especially in the second half of the night and before dawn, the ground has a lot of heat emitted, and access to the atmosphere to compensate for the heat of radiation is very little, the temperature drops very quickly, when the temperature drops to below 0 ℃, near the ground air in the water vapor attached to the ground in the earth, stone, leaves, grass, low house tiles and other objects, it condenses into a white frost of ice crystals. Therefore, China has "frost see sunny day" proverb. If the temperature drops to below 0 ℃, and the lack of water vapor near the ground, the condensation is not frost, but the crops are still subject to frost damage, farmers call this "black frost". If the night is cloudy, the cloud's counter-radiation effect can more constantly compensate for the loss of heat on the ground, the temperature is not easy to fall below 0 ℃, so there will be no frost. So frost generally appear in the clear night.
(B) what kind of weather to see the fireworks is the most wonderful
Every "National Day", "May Day" such a grand festival, people always hope that it does not rain, the sky cloudless best. Because the night of this day, there are often eagerly awaited fireworks event. In fact, a cloudless sky is not the best weather conditions for fireworks, a cloudless sky is like a black hole, it is difficult to set off a strong fireworks effect. The best meteorological conditions for fireworks are: more scattered low clouds, broken cumulus clouds, the height of the bottom of the clouds is about 1,000 meters, the relative humidity is more than 70%, there is more water vapor, the wind is less than 3, the visibility is more than 6 kilometers. It is okay to have drizzle and mist.
In the above meteorological background of the fireworks, through the clouds in the small droplets of particles scattered and refraction, can create an unexpected brilliant background, to achieve a dream-like hazy realm. Coupled with the multiple reflections of the clouds on the sound waves to extend the symphony time, heaven and earth *** sound, more momentum of the swallowing of mountains and rivers.
Geography is a comprehensive discipline, in the production of life in a wide range of applications.
Such as: topography, climate, water, soil, biology (plants, animals)
Industry, agriculture, and other industries and the layout of the city.
What are the common natural geographic phenomena in life Geographic phenomena include whata lot, the sun, moon and stars rise in the east and fall in the west, changes in the length of day and night, changes in the four seasons, rain, snow, hail, changes in the length of the shadow of an object, solar eclipses, lunar eclipses, the temperature, a lot of
What are the common natural geographic phenomena in life
rain, snow, frost, frost, and other freezing fog.
The most common natural phenomenon in life is precipitation, which is divided into two kinds: one is liquid precipitation, which is rain, and the other is solid precipitation, which is snow or hail, etc.Snow is one of the most widespread, most common and most dominant forms of atmospheric solid precipitation. Atmospheric solid precipitation is diverse, in addition to the beautiful snowflakes, but also includes hail that can cause great harm, and we do not often see the snow shrapnel and ice particles.
Atmospheric solid precipitation is divided into ten kinds: snow flakes, star-shaped snowflakes, columnar snow crystals, needle-shaped snow crystals, multi-dendritic snow crystals, axial snow crystals, irregular snow crystals, shrapnel, ice and hail. The first seven are collectively called snow. Why the last three can not be called snow? It turns out that by the gaseous water vapor into solid water there are two processes, one is the first water vapor into water, and then water and then condensed into ice crystals; there is also a kind of water vapor does not go through the water, directly into ice crystals, this process is called water condensation. So the snow is the water vapor in the sky by condensation of solid precipitation.
shotgun: in summer, in high mountain areas, the sky is often a lot of cold water droplets around the crystallization nuclei freeze, the formation of a white, no glossy doughnut-shaped particles, meteorology, this thing is called shrapnel, and many local colloquialisms called it for the rice snow or snow shrapnel. Aragon is generally between 0.3 and 2.5 millimeters in diameter, and is brittle and easily crushed. Shrapnel does not belong to the category of snow, but it is also a kind of atmospheric solid precipitation.
Ice and hail, summer, in the northern plains, often encounter two other atmospheric solid precipitation, which is ice and hail. Ice particles and hail is relatively large can flow droplets around the condensation nucleus layer after layer to freeze and the formation of translucent ice beads. Meteorology on the particle size of not more than 5 millimeters is called ice particles, the particle size of more than 5 millimeters is called hail. Hail brings great harm to agricultural production. According to records, the world's largest hail, bigger than a fist, more than ten centimeters in diameter, weighing more than a kilogram.
Frost, rain and fog, in addition to atmospheric solid precipitation, the ground also often appear another we "surface growth type" of solid precipitation, which is frost, rain and fog. These solid precipitation, although does not belong to the atmosphere solid precipitation, just water vapor in the surface condensation crystallization and freezing and formation. But these solid precipitation, human production activities also have a greater impact.
Frost is more familiar, and it often reduces agricultural yields. In order to avoid frost damage, people put in hard labor. Rainsongs and fogsongs are also not very friendly to humans, and they are usually found in high mountainous areas. They are usually found in high mountainous regions. In excessively cold weather, they form when tiny raindrops or mist droplets hit the surface of an object that has cooled dramatically.
Terrain: The movement of the earth's crust has resulted in a variety of surface features, such as mountains, plains, canyons, and fracture zones.
Climate: Monsoon winds blowing from the South Pacific Ocean bring rain to too many parts of China. If there is a cold front from Siberia, the climate is high pressure and subtropical.
Weather: Strong convective weather causes widespread rainfall.
Rivers: creating delta zones.

Is a cold wave a geographical phenomenon Request some common geographical phenomena in life similar to typhoonsWell, it is a meteorological disaster. Cold wave is a kind of disastrous weather in winter, the masses used to call the cold wave as cold flow. The so-called cold wave, refers to the cold air from high latitudes, in a particular weather situation quickly strengthened and to the middle and low latitudes invasion, resulting in severe cooling along the way, gusty winds and rainy and snowy weather. This cold air southward invasion reaches a certain standard is called a cold wave. (From Baidu Encyclopedia)
Common geographic phenomena: dust storms, dry morning, blizzards, landslides, mudslides, typhoons, floods and so on.

In life, what are the common psychological phenomenaPsychological effect one: the super-limit effect
The famous American writer Mark Twain once listened to the pastor's speech in church. Initially, he felt that the pastor spoke well and moved people to make donations. After 10 minutes, the pastor hadn't finished his speech, so he got a little impatient and decided to donate only some change. After another 10 minutes, the pastor hadn't finished his sermon, so he decided not to donate even a penny. When the pastor finally finished his long speech and began to collect donations, Mark Twain, out of anger, not only did not donate money, but also stole 2 dollars from the plate.
This *** too much, too strong and the effect of too long and cause psychological impatience or resistance to the psychological phenomenon, known as the "overload effect".
The overload effect is often seen in home schooling. For example, when a child makes a mistake, the parents will once, twice, three times, or even four times, five times to repeat the same criticism of a thing, so that the child from the guilt of uneasiness to impatience and even resentment hate. The "forced", there will be "I want this" resistance to the psychology and behavior.
It can be seen that the mother of the child's criticism can not exceed the limit, the child should "make a mistake, only once criticized". If you have to criticize again, it should not simply repeat, to a different angle, a different way of saying. This way, the child will not feel the same error is "grabbed not to let go", boredom, reverse psychology will also be reduced.
Psychological effect two: Rosenthal effect
The famous American psychologist Rosenthal has done such a test:
He put a group of mice randomly divided into two groups: group A and group B, and told the keepers of group A that this group of mice is very smart; at the same time, told the keepers of group B that he said that a group of mice intelligence general. A few months later, the professor tested the two groups of rats through the maze, and found that the rats in group A were really smarter than the rats in group B, and they were able to get out of the maze and find food first.
So Prof. Rosenthal was inspired, and he wondered if this effect could happen to people as well. He went to an ordinary high school, walked casually in a class, and then circled a few names on the list of students and told their teachers that these students had high IQs and were very smart. After some time, the professor came back to this middle school, and the miracle happened again; those few students he had selected were now really at the top of their class.
Why did this happen? It is the magic of suggestion that works.
Everyone in life will accept this or that psychological hints, these hints are positive and negative. The mother is the person whom the child loves, trusts and relies on the most, and at the same time is also the one who imposes the psychological suggestion. If it is a long-term negative and bad psychological hints, it will make the child's mood affected, and even affect its mental health. On the contrary, if the mother has high hopes for the child, positive affirmation, through the eyes of anticipation, approving smile, motivational language to nourish the child's heart, so that the child more self-esteem, self-love, self-confidence, self-improvement, then, how high your expectations, the child's future results will be how great!
Psychological effect three: the barrel effect
"Barrel" effect means: a barrel along the mouth is not flush, it holds the amount of water, not in the barrel on the longest plank, but in the barrel on the shortest piece of wood.
A child's academic performance is like a large barrel, each subject is composed of a large barrel of indispensable planks. The stable formation of the child's good academic performance can not rely on the outstanding performance of a few subjects, but should depend on its overall situation, especially depending on some of its weak links. Therefore, when you find that some of the child's subject deficiencies, you should remind your child to spend more time on this subject, so as to "make up for the shortcomings".
Psychology effect 4: Desi effect
The psychologist Desi once told a fable:
A group of children in front of an old man's house play, screaming all the time. A few days passed and the old man could hardly stand it. So he came out and gave each of the children 10 cents, saying to them, "You have made the place so lively that I feel quite young, and this is a token of my appreciation." The children were delighted, and still came the next day, frolicking as usual. The old man came out again and gave each child five cents, which was not bad, but the children went away happy. On the third day, the old man gave each child only 2 cents, and the children were furious, "2 cents a day, do you know how hard we work!" They swore to the old man that they would never play for him again!
In this parable, the old man's method was simple: he turned the children's internal motivation to play for their own pleasure into an external motivation to play for cents, and by manipulating the external factor of cents, he manipulated the children's behavior. He manipulated the cents as an external factor, and therefore manipulated the behavior of the children.
The Desi effect is often seen in life. For example, parents often say to their children, "If you get 100 points on this test, I'll reward you with 100 dollars", "If you get into the top 5, I'll reward you with a new toy", and so on. Parents may not have thought that it is this improper reward mechanism, the child's interest in learning a little bit of abatement.
In terms of learning, parents should guide their children to set up ambitious ideals, promote their children's emotions and interest in learning, increase their children's motivation for learning itself, and help their children reap the benefits of learning. Parents' rewards can be some things that are helpful for learning, such as books and learning appliances, while some rewards that have nothing to do with learning are best avoided.
Psychology effect five: the south wind effect
The "south wind" effect, also known as the "warmth" effect, originated from the French writer La Fontaine wrote a fable:
The north wind and the south wind than the power to see who can put the pedestrian body coat off. The north wind first came a cold wind, cold, bone-chilling, the result is that pedestrians in order to resist the attack of the north wind, they wrapped the coat tightly. The south wind is blowing slowly, then the wind and sunshine, pedestrians feel the spring warmth on the body, began to unbutton, and then take off the coat, the south wind won the victory.
The reason why the south wind achieves its goal in the story is that it responds to the inner needs of people. This kind of psychological reaction is the "south wind effect", which is the result of inspiring self-reflection and satisfying the needs of the self.
From this, we can see that the use of "sticks", "intimidation" and other "north wind" type of education in the family education is not desirable. The implementation of the warmth of education, more "humane" type of praise, cultivate the child consciously upward, in order to achieve twice the result with half the effort.
Psychological effect of six: Hawthorne effect
The United States outside of Chicago, Hawthorne factory is a manufacturing telephone exchange factories, there are better recreational facilities, health care system and pension system, etc., but the workers are still angry, the production situation is very unsatisfactory. Later, psychology experts specialize in a test, that is, with two years, experts to find workers to talk individually more than 20,000 times, the provisions of the conversation process, to patiently listen to the workers of the factory's various views and dissatisfaction.
This conversation experiment received unexpected results: Hawthorne factory output increased dramatically.
Children in the process of learning and growing up are inevitably confused or dissatisfied, but they can not fully express themselves. As a mother, we should try to make time to talk with our children, and in the process of talking, we should patiently guide our children to speak freely, to say that they are confused about their lives and studies, and to say that they are dissatisfied with their parents, their schools, their teachers, their classmates, and so on.
After the child "said", there will be a kind of venting satisfaction, they will feel relaxed, comfortable. They will then work harder in their studies and be more confident in their lives!
Psychological effect seven: butterfly effect
According to research, a butterfly in the southern hemisphere occasionally flaps its wings to bring up the weak airflow, due to a variety of other factors involved, a few weeks later, it will become a tornado sweeping the United States of America in Texas! Disorder scientists refer to this phenomenon as the "butterfly effect", and made a theoretical expression: a very small cause, after a certain period of time and other factors involved in the role, can be developed into an extremely large and complex influence.
The Butterfly Effect tells us that educating children is no small matter. A correct and appropriate expression of a sentence or a handling of a matter can influence a child's life, while an incorrect and arbitrary one can make the child suffer for the rest of his or her life.
Psychological effect 8: the effect of increasing and decreasing
The "effect of increasing and decreasing" in interpersonal communication refers to the fact that everyone hopes that the other party's liking for him or her will "keep increasing" rather than "keep decreasing". ". For example, many salesmen is to seize the people of this psychological, in weighing goods to the customer is always the first to grasp a small pile in the weighing disk and then a little bit of add into, rather than the first to grasp a large pile in the weighing disk and then a little bit of out.
When we evaluate the child, it is inevitable that his shortcomings and strengths have to be told a lot, and often use the "first praise after the depreciation" method. In fact, this is a very undesirable evaluation method. When evaluating a child, we may want to use the "additive and subtractive effects", such as first saying that the child has some minor faults that do not hurt his dignity, and then giving praise to the appropriate ......
Psychological effect of the ninth: the effect of the doorstep
In daily life, there is often such a phenomenon: in your request for help, if you start to put forward higher requirements, it is easy to be rejected; and if you first put forward smaller requirements, others agree to increase the weight of the requirements, it is easier to achieve the goal, this phenomenon is known to psychologists as the "threshold effect".
In home education, we can also use the "threshold effect". For example, we can put forward lower requirements for the children, and when they are done according to the requirements, they will be recognized, praised and even rewarded, and then gradually increase the requirements, so that the children will be happy to endless positive upward.
Psychological effect ten: labeling effect
During the Second World War, the United States due to the lack of troops, and the war does require a number of soldiers. Therefore, the U.S. military decided to organize the prisoners locked up in the prison to fight on the front line. To this end, the U.S. military sent a few psychological experts to the prisoners to carry out pre-war training and mobilization, and go with them to the front line of combat.
During the training period, the psychologists did not preach too much to them, but especially emphasized the prisoners to write a letter to their closest relatives every week. The content of the letter is standardized by the psychologists and describes how well the prisoners are doing in prison and how they have changed. The experts asked the prisoners to copy the letter carefully and send it to their dearest ones. Three months later, the prisoners went to the front, and the experts asked the prisoners to write in their letters to their loved ones how they obeyed the command and how brave they were. As a result, the performance of the prisoners on the battlefield was no less than that of the regular army, and they obeyed the command and fought bravely in the battle just as they had said in their letters. Later, psychologists called this phenomenon "labeling effect", also known as the psychological effect of suggestion.
This psychological effect has an extremely important role in family education. For example, if we are always yelling at the child "stupid", "pig head", "how so stupid", "even such a simple topic can not do "
This is the first time I've ever seen a child in the world who has been in the same boat as me, and I've never seen a child in the same boat before.
So, shouldn't moms consider quitting mocking and humiliating, blaming and complaining, threatening and intimidating language, and using more motivational language and positive labels for their kids
