Is the continuous snowfall caused by a warming climate?

There are two reasons for the continuous snow:

The first reason is that we are in a La Niña state this year, that is, the sea surface temperature in the eastern equatorial Pacific is lower than normal and below the negative degree, and the impact of this phenomenon on China's climate is very obvious. It's going to have a cold winter, so we can see that this cold winter is coming this year.

The second reason is that the two conditions that must be met for snow or rain are 1Warm and humid air currents from the tropics. 2.

There is cold air from the alpine regions. Areas of winter snowfall (the same is true for areas of summer rainfall) are located near fronts, i.e. at the junction of warm and cold air masses. This position is not fixed, it is determined by the strength of the forces of the two natures.

The cold air mass is weak, and the front and precipitation area are higher latitudes, and the cold air mass is stronger, and the front and precipitation areas are lower latitudes. The land cold high that affects China in winter is the Asian high (also known as the Mongolian and Siberian high pressure) centered in Mongolia and Siberia, and its sphere of influence is very large, which has a great impact on the weather in China, especially in the northern region. The cold air that affected our country in the early part of midwinter this year is relatively weak, and the number of times is not much, even with the cooperation of warm and humid airflow, it is not easy to snow without cold air.

However, since 2008, the Asian high pressure is very active, and the cold air mass continues to form southward to affect our country, resulting in a wide range of windy cooling weather, but because the warm air mass in the south this year is also very active, a large number of warm and humid air currents from the Pacific Ocean and the Indian Ocean frequently visit the southern region, when the strong cold air mass from Siberia, Mongolia quickly moves south to the southern region, and meets with the warm and humid air mass, the cold, warm two just combined. Affected by the combination of these two airflows, there has been a lot of rain and snow in recent times, especially in the Yangtze River basin, and the weather has been maintained at low temperatures for a long time. If there is only a strong cold air mass, and there is no large amount of water vapor provided by the warm and humid air mass, there will only be strong winds and cooling weather in the south; If there is only a large amount of water vapor provided by the warm and humid air mass, and no cold air mass is present, there is no catastrophic weather at all.

And when both are in place, disaster strikes.

It has a certain relationship, because the warming of the climate has changed the shape of the earth's climate, and the ocean currents have changed, so this kind of snowy weather has occurred for days.

It is related to the La Niña climate phenomenon, which is similar to El Niño.

According to scientists, it is caused by climate warming

A warming climate changes the North Pacific Current, which in turn makes cold places colder and hot places hotter.

Yes, a warming climate will make it snowfall less often, I remember when I was a child, the Sichuan-Chongqing region had to snow a few times a year in winter, but in the last few years, it has been more than ten years. It rarely snows in winter.

Why hasn't the north liked snow so much in recent years? This is mainly due to global warming, but why does it cause global warming? It is due to the continuous accumulation of the greenhouse effect, carbon dioxide and other gases are also constantly accumulating in the earth, which constantly leads to the rise of temperature, and finally causes global warming, and now the harm caused by global warming is increasing day by day, the impact on our country is that the winter in the north often does not snow, there will be a lot of bacteria or something, people will be very serious once they get sick, and there is no resistance.

At the same time, icebergs in the Antarctic and Arctic are melting, and some animals, such as polar bears, are on the verge of extinction. Many countries are already in danger, such as Tulua, which is located in the Pacific Ocean, next to the Pacific Ocean, due to global warming, the sea is becoming more and more popular, and many residential areas in Tulua have been flooded, and even more than 10,000 people have already done it elsewhere.

Global warming has not only caused the erosion of many countries near the sea, but it has also had a great impact on our lives, such as some coastal cities that have to move to other places due to the impact of sea level rise.

So now we have to start taking this seriously, and we have to protect the environment, starting with me. Control the trend of global warming, can not let it worsen, for example, we can take the bus in the case of the bus, as much as possible to reduce driving, freon in the refrigerator is one of the main causes of global warming, then we can buy a refrigerator without freon when we buy a refrigerator, protect the environment, everyone is responsible, for our homeland, everyone work together!

Because people do not pay attention to environmental protection, the temperature of the earth is getting higher and higher, which affects people's production and life, and will affect people's living environment, and will also make the number of snowfalls become less and less.

The global climate issue has become the focus of attention of all countries in the world, and climate change will directly affect the future of mankind. However, among the many news we often see, there are reports that the earth will usher in the Quaternary ice age, the global average temperature will fall, and the weather will become colder; It is also said that global warming is caused by the greenhouse effect, and that the average global temperature increases, and the weather becomes hotter.

It's a completely different statement, but people are talking about them, so the question comes up. Which claim is reliable?

Will the future be cold or hot? The answer may disappoint you because both statements are true. They just seem contradictory, but in reality they are not.

What the hell is going on? The Quaternary Ice Age, which began with our home planet. The Earth is said to have been born 4.6 billion years ago.

If you look at the 4.6 billion years of the earth's history, it is a day. The emergence of humanity will only occur at the last minute of the year, while the emergence of human civilization will last until the last second of the year. <>

In other words, compared to the Earth, humanity is only fleeting, and in the past 4.6 billion years, the Earth has undergone tremendous changes. The earth has experienced tens of millions of years of heavy rain, sometimes when it almost melts, when it freezes into snowballs, and when it is full of ** and volcanic eruptions. Overall, the Earth's temperature changes periodically.

According to scientists, temperatures have been relatively high for most of Earth's 4.6 billion years of history. The Earth's surface is not covered by continental glaciers or ice sheets, which can be called the warm period (greenhouse period). <

The proportion of warm periods can reach 85%, and there are some episodes in the warm periods, which are relatively low ice ages, accounting for about 15%. Generally speaking, if the earth's surface is in a state of extremely low temperature for a long time, causing the entire earth's surface to be covered with ice and snow, we call it a glacial age. For example, about 100 million to 100 million years ago, the Earth suffered a severe freeze, historically known as the Snowball Earth.

According to the analysis of scientists, the average temperature of the Earth may have dropped to about minus 50 degrees Celsius during this period. <>

It's not a lack of time, global warming is relative to the past, it doesn't mean that there is no snow, snow is a normal natural phenomenon, and warming does not mean that winter will not come, but that winter may be shortened, snow may be reduced and the temperature in summer is higher.

The argument of global warming is not false. Although it snows in many places, it cannot be said that the earth's environment is normal, and there are many places in the Antarctic and the North Pole where the ice and snow have melted.

I don't think the idea of global warming is wrong, because it's backed by science.

After snowfall, the weather is sunny and warm, and the melting of snow is a physical change. When the snow melts, no new matter is created, but the state of the substance changes, so it is a physical change.

Physical change refers to the fact that although the state of matter has changed, generally speaking, the composition of the substance itself has not changed. For example, changes in position, volume, shape, temperature, pressure, and conversion between gaseous, liquid, and solid states.

A chemical change is a change that creates a new substance. Such as the rust of iron, the fireworks of festivals, the neutralization of acid and alkali, the burning of magnesium strips, and so on. On a macroscopic scale, it can be seen that various chemical changes produce new substances, which is characteristic of chemical changes.

Summary: A change in a new substance is a chemical change.

Physical changes, and no new matter is created.

Rainy seasonRain, on February 18 or 19 or 20 every year, means that the temperature rises, the ice and snow melt, and the precipitation increases, so it is named rain.

The rainy solar term generally starts from February 18 to 20 and ends on March 4 or 5 in the Gregorian calendar. At this time, in the northern hemisphere, the sunshine hours and intensity are increasing, the temperature rises rapidly, and the warm and moist air from the ocean begins to be active, and gradually advances northward to meet the cold air to form rainfall. During the rainy season, the weather is unpredictable, and it is one of the most frequent seasons in the cold wave process throughout the year.

Rain three timesThere are three waits for rain, one is for otters to sacrifice fish, two is for the wild geese to come, and three is for the plants and trees to sprout. It is said that when the rain season comes, the ice on the surface of the water melts, and the otters begin to fish. Otters like to bite fish to death and put them on the shore in order, as if they were sacrificial, so there is a saying that "otters sacrifice fish".

After five days of rain, geese began to fly back from the south to the north. After another five days, the grass and trees began to sprout as the yang energy in the ground rose. Since then, the earth has gradually begun to show a thriving scene.

Light snow.

Light snow is the 20th of the 24 solar terms. The time is on November 22 or 23 of the Gregorian calendar every year, when the sun reaches 240° of ecliptic longitude. Light snow is a solar term that reflects the characteristics of the climate.

The light snow in the solar term is not necessarily related to the light snow in the weather, and the light snow in the light snow solar term is different from the light snow in the daily weather forecast, and the light snow solar term is a climate concept, which represents the climate characteristics during the light snow solar term; Whereas, light snow in the weather forecast refers to snow with less snowfall intensity.

In the ancient book "Qunfang Spectrum", it says:"The light snow is cold and the snow will be heavy, and the ground is not cold and the snow is not big. That is to say, due to the cold weather, the form of precipitation changes from rain to snow, but at this time, because the ground is not cold, the number of snow falls is small, and the amount of snow is not large, so it is called light snow.

Light snow is a season that reflects weather phenomena. The snow is small, and there is no snow on the ground, which is the original meaning of the solar term "light snow". Light snow, like rain and valley rain, is a solar term that directly reflects precipitation.

The light snow season does not mean that it will snow, but that during the light snow season, the temperature drops, and the temperature drops to the point where it can snow, but because the surface temperature is not low enough, even if it falls, the amount of snow will be very small or even none. Therefore, whether it will snow on this day depends on the current weather conditions.

Actually, there is still a period of winter, but it is slowly starting to enter winter. It doesn't seem to feel like autumn right now.

Yes, the cold dew has passed, the temperature is dropping significantly, and winter is about to begin.

Because the cold air is approaching now, it is the early winter season, so be sure to keep warm in the morning and evening.
