Chapter 497 Controlling the Celestial Phenomena
Population is an important parameter to measure the potential of a nation.

Among the population distribution of the world's seven continents, Asia accounts for about 60% of the world's total population, ranking first in the world.

Africa accounts for about 12.3% of the world's total population, Europe accounts for about 10.4% of the world's total population, North America accounts for about 8.1% of the world's total population, South America accounts for about 5.6% of the world's total population, and Oceania accounts for about 0.5% of the world's total population %, Antarctica belongs to the polar ice and snow world, and only penguins live in this place.

The entire planet Lancang River has an extremely uneven population distribution.

East Asia and Southeast Asia are the most densely populated, more than the rest of the planet combined.

In addition, Asia feeds 29.4% of the world's population with 60.00% of the land area.

The reason for this is inseparable from the snow-covered 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 presents a dry yellow landform, which is closely related to the planetary wind belt of the earth.

Regardless of the terrain, the atmosphere in the equatorial region is heated and rises to the high altitude, and sinks from the high altitude near 30 degrees north and south latitude, forming the subtropical high pressure belt in the northern and southern hemispheres, which is what we often call the subtropical high belt.

The air then passes through the northeast trade winds, and the southeast trade winds back to the equatorial convergence zone, and rises again, forming the so-called Hadley cell.

As the air sinks, the temperature rises, and the water vapor is difficult to condense into precipitation.

In this case, this circulation forms the equatorial convergence belt with abundant rainfall, and two arid subtropical high belts.

Seen from space, it can be said that the colors are distinct.

Under the control of the subtropical high in the northern hemisphere, a landmark arid region spanning more than 7000 kilometers from North Africa to West Asia has been formed, 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 belt, they are completely different.

Although this arc-shaped zone extending from East Asia to South Asia is also cut across by 30 degrees north latitude, it is green with lush vegetation and abundant precipitation, and has raised more than half of human beings.

This arc-shaped area is the Asian monsoon belt.

It is the strength of the monsoon that reverses the strength of the planetary wind belt.

The so-called monsoon is closely related to nature and the change of seasons.

As mentioned earlier, the circulation between the equatorial convergence zone and the subtropical high forms the precipitation area and the arid area.

However, the equatorial composite bag does not necessarily stay at the equator, and it will change in different seasons.

Every summer, the point of direct sunlight will move northward from the equator to near the Tropic of Cancer.

At the same time, the global pressure belt and wind belt also moved northward.

When 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, and at the same time, it carries abundant water vapor from the Indian Ocean and the South China Sea, turning the dry season of the Indian Peninsula and the Indochina Peninsula into a rainy season.

If only this is the case, it is far from being able to form a huge Asian monsoon area.

If we look at the distribution of the main monsoon regions around the world, we will find that the area in southeast Asia is particularly large, and it extends northward to the HLJ region outside the customs, far beyond the Tropic of Cancer in latitude.

The key factor behind this is the snow-covered plateau at the foot of Yuezhen Mountain.

In summer, the towering Qinghai-Tibet Plateau receives more solar radiation than the plains, 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 is continuously reduced.

This low-pressure area is like an air pump, continuously sucking up the surrounding low-altitude atmosphere.

As a result, the South Asian monsoon on the Indian Peninsula was greatly enhanced, and at the same time, the equatorial convergence zone was pulled to the south and southwest of China. The moist air flow from the South China Sea and the Pacific Ocean also quickly moved northward, forming a strong East Asian monsoon, sweeping across the eastern part of China. Rainbow, Koryo Peninsula until the northern part of HLJ.

These warm and humid air flow or encounter terrain, or contact with cold air to form precipitation.

Around the tall Qinghai-Tibet Plateau, the intensity of precipitation is particularly high.

For example, Cherrapunji at the southern foot of the Himalayas has an annual rainfall of more than 1 millimeters, which is equivalent to a three-story building. It is a veritable rain pole 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 Ocean, and the Indian Ocean.

In this vast monsoon region,

Almost all crops can find their own environment,
There must be land suitable for farming to 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, which is the birthplace of Chinese civilization.

Eight thousand years ago, Chinese ancestors bred millet and rice.

Shenzhou is a veritable farmer who 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 believed that only hard work will yield results. A brilliant civilization was created on this land and continues to this day.

Although the monsoon has brought vitality and hope, it is also because of the monsoon that it has created unpredictable droughts and floods.

In ancient times when science and technology were underdeveloped, drought and flood disasters were directly related to survival issues.

Closely related to the change of dynasty, it can be described as a major event of the country.

The East Asian monsoon is the result of the joint action of the planetary wind belt and the Qinghai-Tibet Plateau, so it should be very stable.

But in fact, the climate of the entire planet is one.

As the saying goes, one hair can move the whole body, that's exactly what it is.

Although the terrain of the snow-covered plateau has created a strong East Asian monsoon and changed the planetary wind belt.

But above the vast Pacific Ocean, there is still an inescapable force.

Although the snow-covered plateau pulled the equatorial convergence zone and the monsoon area north of the Tropic of Cancer, the subtropical high pressure did not disappear, but remained in the colder Pacific Ocean in the east, which formed the subtropical high pressure belt in the western Pacific Ocean.

We call it West Pacific Vice High for short.

The airflow around the West Pacific subtropical high rotates clockwise around the high pressure, which is a typhoon.
It drives the warm and humid air over the ocean on the south side, and when it rotates to the north side, it meets the cold and warm air going south in China to form precipitation, and this area is the precipitation rain belt in China.

Therefore, the location and intensity of the West Pacific subtropical high determine the location and intensity of precipitation in eastern China.

Its location is different in different seasons and years. Sometimes it lands in Guangdong and Guangxi, sometimes it lands in Fujian, or it lands from Qilu Peninsula.

Use scientific means to analyze meteorological changes and find out the laws, then you can use them.

Of course, the above knowledge is the accumulation of Yue Zhenshan's previous life.

In the previous high school geography, there were introductions about geography and climate.

Now, Yue Zhenshan is going to use his extraordinary means to manipulate the planet's weather changes.
