What causes the plane to be turbulent in the air?

In recent years, airplanes have become one of people's favorite ways to travel, airplanes are very convenient, fast, and very safe, generally speaking, civil aviation.

The passenger planes are very stable, and passengers can also enjoy the joy of travel in the process, but sometimes the plane will be turbulent, what is the reason for this?

With the rise of the altitude of the aircraft, you will see many different landforms, such as plateaus and deserts, the climatic characteristics of these terrains are different, and because of the different landforms, the resistance in the air is also different, so the air will move vertically, affecting the stable situation of the aircraft in the air.

Frequent flyers know that when the weather changes, the flight will be delayed or the flight will be cancelled, especially during thunderstorms and windy weather or typhoons. Especially in the summer, there are more thunderstorms, and in the autumn, the wind is stronger, so during these two seasons, the plane is very prone to turbulence during the journey. And in the process of the plane, due to the sunlight.

The air on the ground will be heated and expand, so the cold air will fall, and the convection will be formed in the air, which will cause the aircraft to turbulence. This symptom is very noticeable in many planes when they fly at noon.

When the weather is bad, such as a thunderstorm.

Both cold fronts and hot thunderstorms cause air to move up and down the air, also known as wind shear.

When the plane passes by, it will produce very strong turbulence, and in severe cases, there may be flight accidents. But the pilot is not ignorant of the upcoming aircraft turbulence, in all flight plans, the turbulence index near the waypoint will be displayed, and the flight technicians will also prepare accordingly in advance, and the crew members of the aircraft will also be the first to remind passengers through the radio for the first time, and will slow down, so you don't have to worry.

It is because the airflow is unstable, the speed and intensity of the aircraft have changed, the airflow in the air is unevenly distributed, and the turbulence of the small airflow of the aircraft is a very normal phenomenon, which does not affect the flight, and passengers need to fasten their seat belts.

Under the influence of the air, the higher the plane flies, the greater the air flow will be, and the aircraft may be delayed in bad weather.

I feel that it has to do with air reasons, environmental reasons, temperature reasons, geographical location reasons, and operational reasons. So when we encounter this situation, don't be afraid.

The reason why the plane will be bumpy during the flight is actually that it has encountered a turbulent area, and these situations will also make people feel more frightened. Airplanes have become a very common mode of transportation by now, but there are still people who are particularly afraid of flying. In order not to be scared, there is really no need to fly.

The climate is smooth, and the flight of the aircraft is also stable

If it is in a place where the climate is relatively stable, the aircraft is still flying in a particularly stable state, so there is no serious turbulence in the aircraft at this time, if the aircraft flies to some places where the air flow is particularly chaotic, the air flow will drive, so the aircraft will suddenly flutter at this time, which affects everyone's balance system. At this time, you will feel that the plane is jolting very strongly, which is also relatively common.

There are three types of turbulence that cause the aircraft to turbulent

This situation is particularly complicated, after all, there are many types of turbulence, which can be affected by the terrain, climate, and even the seasons, and once these three conditions occur, they will also lead to turbulence. Turbulence can even vary in magnitude, as can be the case when an aircraft enters a plateau. Especially in the summer, there are more turbulence than in the winter.

Encountered in the summerThunderstorms, the plane was heavily turbulent

Because thunderstorms are often encountered in summer, this kind of weather itself is particularly complicated, and aircraft flying at high altitudes are particularly susceptible to these air currents, and we will feel strong turbulence when sitting in the plane. Once you encounter such a situation, it will make everyone feel that the atmosphere in the plane is more tense, and it is indeed related to everyone's life, our life is closely related to this plane, and no one wants to encounter such a thing when taking a plane.

However, don't be nervous when the plane is turbulent, and act according to the instructions of the flight attendants, who are professionally trained and know what to do to keep everyone from harming themselves.

It may be because of the air current, there will be this kind of turbulence, or it may be because of the wind, so it will cause turbulence, which is a normal situation and we don't need to worry.

Aircraft may be affected by the weather, the atmosphere, the terrain or the season.

This is due to air convection, which is caused by the air entering the troposphere during flight, which is why there is turbulence.

Because there are a lot of air currents in the sky, these air currents will affect the normal flight of the aircraft, so there will be turbulence.

Before understanding the causes of aircraft turbulence, it is necessary to understand the troposphere and stratosphere. The troposphere is a layer of the earth's atmosphere close to the ground, which is greatly affected by the surface, not only the regular vertical movement of the air and the irregular turbulence are quite strong, clouds, fog, rain, snow and many other weather phenomena occur in the troposphere, while the stratosphere is above the troposphere. Relatively speaking, the air is thin, the visibility is high, the atmosphere is convection, and birds cannot fly to the stratosphere, so the stratosphere is most suitable for aircraft flight.

However, the cruising altitude of the aircraft is more, most of them are at the top of the troposphere to the bottom of the stratosphere, and they also have to pass through the troposphere when they climb and fall, so most flights are affected by the weather, as long as there is air flow in motion, just like when driving can not touch the flat ground, bumps are inevitable. Therefore, the basic cause of aircraft turbulence is the presence of turbulence in the atmosphere. These unstable air currents range in a wide range and vary in direction and velocity.

When the aircraft enters a turbulent vortex similar to the size of the fuselage, all parts of the aircraft will be affected by the airflow in different directions and speeds, and the original aerodynamic force and the balance of torque will be destroyed, resulting in irregular motion. The passage of an airplane from one vortex to another causes vibrations. When the natural vibration cycle of the aircraft is comparable to the turbulent pulsation cycle, the turbulence of the aircraft becomes very intense.

Both vertical and horizontal gusts of air present in turbulence can cause aircraft turbulence.

Bumps are related to weather, wind speed, etc.; It is normal for an airflow to fluctuate when an aircraft passes over an area, which can also cause the aircraft to jolt.

Airplanes generally fly in the troposphere below 10,000 meters, and due to air convection, the aircraft will be turbulent. Generally speaking, it is mainly affected by the following factors:

1) Affected by the terrain: flying in mountainous areas, plateaus and desert areas, the terrain makes the air resist, causing the vertical movement of the air;

2) Affected by the season: due to more thunderstorms in summer and stronger winds in autumn, there will be more bumps in these two seasons.

The reason for the turbulence of the aircraft is due to the turbulence in the atmosphere, and these unstable air currents can vary in scope and direction, and speed. When the aircraft enters the turbulent vortex similar to the size of the fuselage, all parts of the aircraft will be affected by the airflow in different directions and speeds, and the original balance of aerodynamic force and torque will be destroyed, resulting in irregular motion and turbulence.

Turbulence

Both vertical and horizontal gusts of air present in turbulence can cause aircraft turbulence, and vertical air flow plays a greater role than horizontal air flow. According to the causes of turbulence, it can be divided into: thermal turbulence, dynamic turbulence, emptying turbulence and track turbulence.

Thermal turbulence is mainly caused by the uneven horizontal distribution of air temperature caused by surface heating, which often occurs in the lower troposphere and at low latitudes, mostly in the noon and early afternoon of summer.

Dynamic turbulence refers to the turbulence caused by the obstruction of air movement near the surface and the obvious shear of the spatial distribution of wind.

Clear sky turbulence, also known as upper-air turbulence, is related to the thermal and dynamic factors of the atmosphere in the upper air, and strong turbulence occurs when the temperature field and wind field change sharply. Clear sky turbulence mostly occurs in the upper troposphere and stratosphere, which is an important factor causing high-altitude flight turbulence.

The plane was jolting

Aircraft turbulence refers to the phenomenon of sudden up and down, left and right shaking and fuselage flutter in the flight of the aircraft, and the aircraft turbulence is mainly caused by the aircraft flying into the disturbed airflow area, and the disturbed airflow makes the aerodynamic force and torque acting on the aircraft unbalanced, and the flight altitude, flight speed and aircraft attitude are suddenly changed.

The turbulence intensity of the aircraft is related to the intensity of the disturbance airflow, flight speed, wing load, etc., and is usually divided into three levels: weak, medium and strong. Moderate or above turbulence will make the aircraft instrument indication abnormal, difficult to maneuver, and affect air formation, shooting, bomb dropping, refueling and aerial photography.

Airplanes generally fly in the troposphere below 10,000 meters, and due to air convection, the aircraft will be turbulent. Generally speaking, it is mainly affected by the following factors: (1) Affected by the topography:

Flying in mountainous areas, plateaus, desert areas, the terrain puts the air in drag, causing the air to move straight. (2) Affected by the season: due to more thunderstorms in summer and stronger winds in autumn, the bumps in these two seasons will seep more limbs.
