40 degrees south latitude and 40 degrees north latitude, 45 degrees north latitude where is China

At 40° north and south, it is in the prevailing westerly wind belt from a global perspective.

The northern hemisphere is southwesterly and the southern hemisphere.

It's a northwesterly wind. The world is divided into 7 pressure zones and 6 wind zones.

From the equator to the two levels, there are the equatorial low pressure belt, the northeast (southeast) trade wind belt, and the subtropical high pressure belt.

It is prevalent in the westerly wind belt, the subpolar low pressure belt, the polar easterly wind belt, and the polar high pressure belt.

Wind belts and direct sun spots.

There is a direct relationship.

The sun shines directly on the equator, which is the hottest at the equator, and the hot air rises, forming an equatorial low pressure zone.

The rising air on the surface, supplemented by air from the north and south sides, is deflected by the geostrophic deflection force.

Under the action, the northeast trade wind belt in the northern hemisphere and the southeast trade wind belt in the southern hemisphere were formed.

The hot air rising from the equator spreads to the north and south, and at the same time is deflected eastward by the geostrophic deflection force, and finally at 30° north and south latitude

The left and right positions become completely west-to-east, and no longer move towards high latitudes.

Move. Air accumulates and then sinks here, forming a subtropical high.

Vice High). The air sinking from the subtropical high moves to both sides on the surface of the earth, and the air moving to high latitudes forms a prevailing westerly wind belt under the action of geostrophic deflection force.

Speaking of the polar regions, the polar regions are cold all year round because the surface of the earth is cold, and the cold air sinks, forming a polar high pressure belt.

The cold air from the polar subsidence moves to low latitudes, forming the polar easterly wind belt under the action of geostrophic deflection force.

The polar easterly wind and the prevailing westerly wind meet at about 60 degrees north and south latitudes, the polar easterly wind sinks coldly, and the prevailing westerly wind is forced to lift warmly, forming a front called the polar front, which provides precipitation all year round. The forced uplift of air forms a subpolar depression band on the surface.

Atmospheric circulation. Air pressure with wind belt.

By the way, this is not an astronomical problem...

The topographic units passing through China at 40 degrees north latitude from west to east mainly include the Tarim Basin, the Taklamakan Desert, the Loess Plateau, the Inner Mongolia Plateau, the Yellow River, the Taihang Mountains, the North China Plain, the Bohai Sea, and the Liaodong Peninsula.

China's topography is high in the west and low in the east, and is distributed in a stepped manner. The terrain is varied, with a vast mountainous area. The terrain is high in the west and low in the east, and it is inclined to the ocean, which is conducive to the moist air flow over the ocean to penetrate deep into the interior and form precipitation. On the other hand, many large rivers have flowed eastward, connecting the east and the west, and facilitating the economic ties between the coastal areas and the interior.

The river descends from west to east, and the river has a large drop, and the water energy is abundant. The diverse terrain has provided favorable conditions for the development of diversified agriculture, forestry, animal husbandry, and sideline operations in accordance with local conditions. Mountainous areas have advantages in the development of forestry, animal husbandry, tourism, mining, etc.; However, the mountainous area has a rugged ground and inconvenient transportation, which is not conducive to the development of planting industry.

Due to the vast area of mountainous areas and the small number of plains, there is a shortage of cultivated land resources.
