What s going on with airplane turbulence? What causes the plane to be turbulent in the air?

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.

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.

China's top 10 bumpy routes: Shanghai - Chengdu, Chengdu - Kunming, Chengdu - Lhasa, Xi'an - Kunming, Kunming - Lincang, Mianyang - Shanghai, Chengdu - Jiuzhaigou, Kunming - Chongsui Bench Qing, Chengdu - Chongqing, Urumqi - Yili.

Airplanes will always experience turbulence from take-off to landing, and when turbulence is unavoidable, fastening a seatbelt is the safest way to prevent it. Some bumps can be avoided in conjunction with weather phenomena, but others are simply unpredictable.

The most effective way to prevent bumps is to avoid them, rather than slowing them down. According to the principle of meteorology, many weather phenomena such as thunderstorms, wind shear, and cumulonimbus clouds will produce strong turbulence, and when the flight encounters these weather, the pilot can appropriately yaw or change the route to avoid these weather, so as to prevent the harm caused by turbulence.

If all the people on the plane are wearing seat belts, then even in the event of sudden turbulence, the hazards caused by the turbulence can be minimized and the personal safety of passengers can be ensured.

Therefore, the crew should be prepared for cooperation before the flight, and the air should make timely passenger announcements according to the flight conditions and weather conditions, reminding all the personnel on the plane to fasten their seat belts is very important.

The main causes of aircraft turbulence are as follows:

1.Health Impacts: Prolonged jolting can have adverse effects on the body, such as dizziness, headache, nausea, vomiting, etc., especially for passengers with high blood pressure, cardiovascular disease or other health problems.

2.Psychological stress: The turbulence of the aircraft can make passengers feel panicked, anxious and uncomfortable, which can bring great inconvenience and psychological stress to the trip, and even cause psychological trauma.

3.Airborne injuries: Prolonged jolting may cause body injuries, such as cervical and lumbar spine injuries, so passengers need to use seat belts correctly, and at the same time, it is recommended that passengers do proper warm-up exercises before take-off and after landing.

4.Damage to the aircraft itself: Severe turbulence can adversely affect the aircraft or equipment, which may cause machine failure and hail, affecting flight safety.

5.Delayed or cancelled flights: If the aircraft is heavily turbulent, it may result in grounding, delaying or cancelling flights, causing great inconvenience and financial loss to passengers.

Therefore, when flying, passengers should follow the crew and safety instructions, fasten their seat belts properly, and follow the flight regulations to reduce the adverse effects of turbulence on the body and mind.

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.
