Chapter 508 Controlling the Celestial Phenomenon
Population is an important parameter to measure the potential of a nation.
Among the world's seven continents, Asia accounts for approximately 60% of the world's total population, ranking first in the world.
Africa accounts for approximately 12.3% of the world's total population, Europe accounts for approximately 10.4% of the world's total population, North America accounts for approximately 8.1% of the world's total population, South America accounts for approximately 5.6% of the world's total population, and Oceania accounts for approximately 0.5% of the world's total population. %, Antarctica belongs to the polar ice and snow world, where only penguins live.
The entire planet Lancang River has extremely uneven population distribution.
East and Southeast Asia are the most densely populated, with more people than the rest of the planet combined.
In addition, Asia feeds 60% of the world's population with 29.4% of its land area.
The reason for this is closely related to the snowy plateau at the foot of Yuezhen Mountain.
If we change our perspective and observe the Earth from space, we will find that near 30 degrees north latitude, most of the land shows an arid yellow landform. This scene is closely related to the Earth's planetary wind belt.
Regardless of topography, the atmosphere in the equatorial region is heated and rises to high altitudes, then sinks from high altitudes near 30 degrees north and south latitude, forming the subtropical high pressure belts in the northern and southern hemispheres, which we often call the subtropical high belts.
This air then returns to the equatorial convergence zone through the northeast trade winds and southeast trade winds, and rises again to form the so-called Hadley cell.
As the air sinks, the temperature rises and it becomes difficult for water vapor to condense into precipitation.
In this case, this circulation creates the wet equatorial convergence zone and two dry subtropical highs.
Seen from space, the colors are distinct.
Under the control of the Northern Hemisphere subtropical high, the largest arid area with an east-west span of more than 7,000 kilometers is formed from North Africa to West Asia, including the Sahara Desert, the Arabian Peninsula and the Iranian Plateau.
This span is equivalent to the distance from the northernmost point of Neon to the southernmost point of India.
Although both are in the Northern Hemisphere subtropical high zone, they are completely different.
Although this arc-shaped area extending from East Asia to South Asia is also cut through by 30 degrees north latitude, it is a green area with lush vegetation and abundant rainfall, and has nurtured more than half of the human race.
This arc-shaped area is the Asian monsoon belt.
It is the power of the monsoon that reverses the force of the planet's wind belts.
The so-called monsoon is naturally closely related to the changes in the four seasons.
As mentioned earlier, the circulation between the equatorial convergence zone and the subtropical high forms precipitation areas and dry areas.
However, the equatorial composite bag may not stay at the equator and will change in different seasons.
Every summer, the direct point of the sun moves north from the equator to near the Tropic of Cancer.
At the same time, the global pressure belt and wind belt also move northward.
As the equatorial convergence zone advances northward, the southeast trade wind belt also crosses the equator.
Under the action of the geostrophic deflection force, it is deflected into the southwest monsoon, which also carries abundant water vapor from the Indian Ocean and the South China Sea, transforming the dry season of the Indian Peninsula and Indochina into the rainy season.
If it were just like this, it would still be far from forming a huge Asian monsoon area.
If we look at the distribution of major monsoon areas around the world, we will find that the southeastern part of Asia is particularly large, and extends all the way north to the HLJ area outside the Great Wall, far beyond the Tropic of Cancer in latitude.
The key factor behind this is the snowy plateau at the foot of Yuezhen Mountain.
In summer, the towering Qinghai-Tibet Plateau receives more solar radiation than plain areas, and the surface temperature rises, forming a strong thermal difference between land and sea. At the same time, the atmosphere is heated and the surface pressure continues to decrease.
This low-pressure area is like an air pump, continuously sucking up the surrounding low-altitude atmosphere.
This greatly strengthened the South Asian monsoon on the Indian Peninsula, and also pulled the equatorial convergence zone to southern China and southwest China. The moist airflow from the South China Sea and the Pacific Ocean also rapidly advanced northward, forming a strong East Asian monsoon, sweeping across eastern China, Niu Hong, Korea Peninsula and the northern region of HLJ.
These warm and moist airflows either encounter terrain or come into contact with cold air, forming precipitation.
Precipitation intensity is particularly high around the tall Tibetan Plateau.
For example, Cherrapunji at the southern foot of the Himalayas has an annual rainfall of more than 10,000 millimeters, which is equivalent to a three-story building. It is truly the rainiest place in the world.
The snowy plateau is like this. By adding buffs to the original monsoon, it has created the largest monsoon system and monsoon area on earth between Asia, the Pacific, and the Indian Ocean.
It is in this vast monsoon area that
Almost all crops can find their own suitable environment,
Only with land suitable for farming can we feed billions of people.
One-third of these billions of people live in the land between the Qinghai-Tibet Plateau and the Pacific Ocean, which is the traditional Chinese region. This area is the birthplace of Chinese civilization.
Eight thousand years ago, the ancestors of China bred millet and rice.
China is a veritable farming school that has accumulated the agricultural wisdom of the 24 solar terms and invented advanced farming methods.
The environment is the deep foundation of culture. It is precisely because of the monsoons and precipitation year after year that the ancestors of China firmly believe that hard work will lead to harvest, and they created a glorious civilization on this land that continues to this day.
Although the monsoon brings vitality and hope, it is also because of the monsoon that it creates unpredictable droughts and floods.
In ancient times when science and technology were underdeveloped, drought and flood disasters were directly related to survival issues.
It is closely related to the change of dynasty and can be described as a major national event.
The East Asian monsoon is the result of the interaction between the planetary wind belt and the Tibetan Plateau. It is said to be very stable.
But in fact, the climate of the entire planet is one.
As the saying goes, a single move affects the whole body, and it is true.
Although the terrain of the snowy plateau creates a powerful East Asian monsoon, it changes the planetary wind belt.
But above the vast Pacific Ocean, there is a force that is difficult to get rid of.
Although the snowy plateau pulls the equatorial convergence zone and the monsoon area north of the Tropic of Cancer, the subtropical high pressure does not disappear, but remains in the cooler Pacific Ocean in the east, forming the subtropical high pressure belt in the western Pacific.
We call it the Western Pacific Deputy High Commissioner for short.
The airflow around the Western Pacific Subtropical High rotates clockwise around the high pressure. This is a typhoon.
It drives up the warm and moist airflow on the southern ocean. When it rotates to the north, it meets the cold and warm air from the south of China to form precipitation. This area is the precipitation rain belt of China.
Therefore, the location and intensity of the western Pacific subtropical high determine the location and intensity of precipitation in eastern China.
Its location varies in different seasons and years. Sometimes it lands in the Guangdong and Guangxi regions, sometimes in the Fujian region, or from the Qilu Peninsula.
Use scientific means to analyze meteorological changes and find the laws, which can be used.
Of course, the above knowledge is accumulated over a lifetime on Yue Zhenshan.
In previous lives, high school geography and geography and climate were all introduced.
Now, Yue Zhenshan is ready to use his extraordinary means to control the weather changes of the planet.
Chapter 509 Dragon Vein Spirit Bead
If you want to control weather changes, you must first find the key factors that affect China's weather.
There are two key factors affecting China's climate.
The first is the snowy plateau. The low-pressure area formed by the snowy plateau is like an air pump, continuously sucking up the surrounding low-altitude atmosphere, which can strengthen the submonsoon.
If a miracle building is built on the snowy plateau, it can be used to strengthen the geographical effect of the snowy plateau.
This allows water vapor from the Indian Ocean to cross the Himalayas and penetrate deep into the hinterland of China. Through the power of miraculous buildings, this water vapor is transformed into ice and snow and deposited on the snowy plateau.
After the ice and snow melted, rivers formed into the arid northwest of China.
Through extraordinary means, the deserts and deserts in the Western Region were transformed into fertile soil.
In this way, the population that China mainland can support will skyrocket again, and population is the foundation of the nation. By then, the disappeared ancient country of Loulan and many areas in the Western Region will revive again and become full of vitality.
This area of the Snowy Plateau seems to be very deserted and difficult to develop.
In fact, it is very important to China.
Since ancient times, Chinese civilization has regarded the Yellow River as the river of civilization's origin. This ancient river, which has nurtured Chinese civilization for five thousand years, has its source in the snow-covered plateau.
Not only does the Yellow River originate from the snowy plateau, but other major rivers also originate from the snowy plateau, including the Yangtze River, Dulong River, Nujiang River, Lancang River, Pearl River, Brahmaputra River, Bhagirati River, Senge Zangbo River, and Yuanjiang River.
The snow-covered plateau is not only very important to the civilization of China, but is also crucial to the satellite countries surrounding China.
The entire snow-covered plateau is equivalent to an Asian water tower.
Now, Yuezhen Mountain is located in the middle section of the Kunlun Mountains, next to the Tanggula Mountains.
This area is the source of the Yangtze River, Yellow River and Lancang River.
This area is the source of the Three Rivers. The source of the Three Rivers is roughly south of the Kunlun Mountains and north of the Tanggula Mountains. The source of the Yellow River is Kariqu, which originates from the Bayan Har Mountains. The source of the Lancang River is Zhaqun, which originates from the Tanggula Mountains. At the northern foot, the source of the Yangtze River is Dangqu, which originates from the swamps at the northern foot of Tanggula Mountain.
It is very rare in the world for three major rivers to originate from one area at the same time.
This does not include the Indian Ocean water system originating from the southern foot of Tanggula Mountain.
The Sanjiangyuan is one of the regions with the richest water resources in the world. 25% of the total water volume of the Yangtze River, 49% of the total water volume of the Yellow River, and 15% of the total water volume of the Lancang River come from this area.
Of course, the further north the river goes, the smaller the proportion of supply in the middle and lower reaches will be.
Especially the Yellow River, which has the smallest water volume, relies on upstream areas for nearly half of its supply.
The Sanjiangyuan region is densely covered with rivers, lakes and swamps, and snow-capped mountains and glaciers are widely distributed. It is the region with the highest altitude, largest area, and most concentrated distribution in the world. The wetland area here is about 73,000 square kilometers.
