Turbulence Scale And Types!!!
Are you someone who gets nervous when there is even slight turbulence on the plane? Or are you curious to know more about different types of turbulence that can occur during a flight?
Either way, this blog post is for you. In this article, we will delve deeper into the world of turbulence and explore its various types while also discussing the scale used to measure it. So buckle up and get ready to learn more about this fascinating aspect of flying!
The 4 Grades Of Turbulence
Turbulence is classified into four grades, according to the severity of the conditions: light, moderate, severe, and extreme.
Light turbulence is usually just a little bumpy and doesn’t last long. It’s often caused by thermal currents rising from the ground on hot days. Moderate turbulence is more intense and can last for several minutes. It’s often caused by thunderstorms or by jet streams.
Severe turbulence can be very intense and can last for several hours. It can cause aircraft to lose altitude and can be dangerous for passengers and crew alike. Extreme turbulence is the most intense kind of turbulence and can last for days or even weeks. It’s often caused by hurricanes or other large weather systems.
Light Turbulence
Turbulence Scale And Types!
Light turbulence refers to slight bumps and jolts during a flight. This type of turbulence is usually caused by atmospheric conditions such as wind shear, thermal updrafts, or thunderstorms. While it can be jarring, light turbulence is generally not dangerous.
Moderate Turbulence
Turbulence is classified into five categories, ranging from light to severe. Moderate turbulence is the third level and is characterized by large bumps or jolts. This type of turbulence can occur without warning and can make it difficult to walk or stand. The seat belt sign will usually be turned on during moderate turbulence.
Severe Turbulence
Turbulence can be classified into different categories depending on its severity. The most common classification is the turbulence intensity scale, which rates turbulence on a scale from 1 to 6, with 1 being light turbulence and 6 being severe.
Severe turbulence is the most dangerous type of turbulence and can often lead to injuries or even fatalities. It is important to remain calm and follow the safety procedures during these times. If you are ever in doubt, always ask a flight attendant for help.
Extreme Turbulence
What is turbulence? In fluid dynamics, turbulence or turbulent flow is fluid motion characterized by chaotic changes in pressure and flow velocity. It is in contrast to a laminar flow, which occurs when a fluid flows in parallel layers with little mixing between them. Turbulence is caused by excessive kinetic energy in the fluid and typically exists at high velocities and/or low viscosities.
As turbulent flow occurs, pockets of low-pressure regions form amidst the high-pressure regions. These low-pressure regions are responsible for the chaotic nature of turbulence. Because of the way that they interact with the surrounding fluid, these low-pressure regions cause turbulence to exhibit a number of strange properties:
Turbulent flow is incoherent – that is, it lacks pattern or structure. This makes it difficult to predict and difficult to control.
Turbulent flow is unpredictable – because it lacks pattern or structure, it is very difficult to predict how a turbulent flow will evolve over time. This makes it challenging for engineers to design systems that can withstand or take advantage of turbulence.
Turbulent flow is unstable – because it lacks pattern or structure, turbulent flow can be easily disturbed by external forces such as wind gusts or obstacles in the environment. This can lead to dangerous situations for both people and objects within a turbulent flow field.
Turbulent flow is dissipative – because of the way that low-pressure regions interact with the surrounding fluid, energy
Types Of Turbulence
Turbulence Scale And Types!
Turbulence can be classified into several types, each with its own characteristics. The most common types of turbulence are:
-Convective turbulence: This is caused by thermal updrafts and downdrafts in the atmosphere. It is usually found in the daytime over landmasses and is the type of turbulence most often encountered by airline passengers.
-Mechanical turbulence: This is caused by wind blowing over obstacles such as mountains or buildings. It is more common at night and over water and can be more severe than convective turbulence.
-Jet stream turbulence: This is caused by strong winds flowing through narrow channels in the atmosphere, such as jet streams. It can be severe and is most common at high altitudes where jets fly.
-Clear air turbulence: This is caused by small-scale disturbances in the atmosphere that are not associated with any visible weather phenomenon. It can occur anywhere, at any time, and can be severe.
Clean Air Turbulence
Turbulence is one of the most common causes of flight delays and cancellations. It can be caused by a number of factors, including weather, aircraft type, and runway length. Turbulence can be classified into two types: clear air turbulence (CAT) and mechanical turbulence (MT).
CAT is the most common type of turbulence and is caused by atmospheric conditions such as air pressure, temperature, and humidity. CAT can be further divided into three categories: light, moderate, and severe. Light CAT is generally not dangerous and only causes minor discomfort to passengers. Moderate CAT can cause significant discomfort and may even injure passengers if they are not properly secured. Severe CAT can cause damage to the aircraft and serious injury or death to passengers.
MT is less common than CAT but can be more dangerous since it is caused by the aircraft itself. MT can be caused by a number of factors, including wake vortexes from other aircraft, engine failure, or mechanical problems with the aircraft. It can be further divided into three categories: light, moderate, and severe. Light MT generally only causes minor discomfort to passengers. Moderate MT can cause significant discomfort and may even injure passengers if they are not properly secured. Severe MT can cause damage to the aircraft and serious injury or death to passengers.
Thermal Turbulence
Thermal turbulence is a type of fluid instability that is caused by temperature differences within the fluid. This can lead to convective motions which can be either laminar or turbulent. The onset of thermal turbulence can be predicted by the Rayleigh-Bénard instability criterion. Turbulence can also be created artificially by heaters placed in a fluid.
Temperature Inversion Turbulence
Temperature inversion turbulence is a type of turbulence that can occur when the temperature of the air decreases with height. This can happen when warm air is trapped beneath a layer of cooler air. The warmer air is less dense than the cooler air and so it rises. This can cause the formation of eddies and swirls in the atmosphere which can lead to turbulence.
Mechanical Turbulence
Mechanical turbulence is caused by the motion of a fluid over an obstacle. The most common type of mechanical turbulence is flow over a solid object, such as a wing. When the fluid (air) moves around the obstacle (wing), it creates eddies in the flow. These eddies can be large or small, and they can occur on any scale.
Large-scale eddies are created by the overall motion of the fluid, while small-scale eddies are created by local disturbances in the flow. The size and strength of the eddies depend on the speed of the fluid and the size of the obstacle.
The most important factor in creating turbulence is the Reynolds number, which is a measure of the ratio of inertial to viscous forces in a flow. In general, high Reynolds numbers correspond to turbulent flow, while low Reynolds numbers correspond to laminar flow.
There are many different types of turbulent flows, depending on the specific circumstances under which they occur. Some common types include boundary layer turbulence, wake turbulence, and jet turbulence. Each type has its own characteristic features that make it distinct from other types of turbulence.
Frontal Turbulence
Frontal turbulence is caused by a change in the windspeed and direction along a frontal boundary. This type of turbulence is most common in the vicinity of a cold front, where the wind speeds increase and the direction changes from out of the south to out of the northwest. The increased wind speeds lead to an increase in shear, which can cause strong updrafts and downdrafts. These strong updrafts and downdrafts can lead to severe turbulence.
Mountain Wave Turbulence
Mountain wave turbulence is a type of mechanical turbulence that occurs when air flows over mountains. The waves can be either internal (generated within the atmosphere) or external (generated by the interaction of the atmosphere and the solid earth). Mountain waves are a major source of mechanical energy in the atmosphere and can cause significant damage to aircraft and other objects in their path.
Mountain wave turbulence is caused by the interaction of air molecules with mountains. As air molecules flow over the mountain, they are forced to change direction. This change in direction creates a series of waves that can propagate through the atmosphere. These waves can be either internal or external. Internal waves are generated within the atmosphere and are not affected by the solid earth. External waves are generated by the interaction of the atmosphere and the solid earth.
Mountain waves are a major source of mechanical energy in the atmosphere. The energy from these waves can cause significant damage to aircraft and other objects in their path. Turbulence caused by mountain waves is typically classified as moderate or severe depending on its intensity.
Thunderstorm Turbulence
While turbulence is generally safe, it can be a major inconvenience during air travel. There are different types of turbulence, each with its own characteristics.
Thunderstorm turbulence is the most severe type of turbulence. It is caused by strong updrafts and downdrafts within thunderstorms. These updrafts and downdrafts can create strong gusts of wind that can jostle an airplane. Thunderstorm turbulence can also be accompanied by other severe weather conditions, such as lightning, hail, and heavy rain.
Thunderstorm turbulence can be very dangerous for airplanes and their passengers. It is important to avoid flying through thunderstorms whenever possible. If you must fly through a thunderstorm, make sure to buckle your seatbelt and keep your seat in an upright position.
Wake Turbulence
Wake turbulence is turbulence that is created by the passage of an aircraft through the air. It is also known as wake vortex or Wake Vorticity. Turbulence is a chaotic and unpredictable movement of air. The energy of turbulence can be dissipated through various means such as friction, pressure, or heat.
Wake turbulence can be classified into two types: vortices and shear layers. Vortices are areas of rotating air that are caused by the wings of an aircraft. Shear layers are areas where the airflow is disrupted and has abrupt changes in velocity or direction.
Both types of wake turbulence can be dangerous to other aircraft. Vortices can cause a rollover or yawing motion, while shear layers can cause an aircraft to lose lift and crash. Wake turbulence can also damage airplane engines and cause structural damage to an aircraft.
For all these reasons, it is important for pilots to be aware of the potential dangers of wake turbulence and to avoid it when possible.

There are several ways to cope with turbulence while in flight:
1. Use an anti-anxiety medication: If you are prone to anxiety or fear during flights, your doctor may prescribe an anti-anxiety medication to help you cope with turbulence.
2. Distract yourself: If you start to feel anxious during periods of turbulence, try to distract yourself with something else. Listen to music, read a book, or chat with a fellow passenger.
3. Stay hydrated: Drinking plenty of fluids will help keep your body relaxed and may help reduce the effects of motion sickness. Avoid caffeine and alcohol, which can dehydrate you and make symptoms worse.
4. Practice deep breathing: Taking slow, deep breaths will help relax your body and mind.
Final Notes
As we have seen, there are different types of turbulence, each with its own characteristics. The most important thing to remember is that turbulence can be dangerous and even deadly. It is important to be aware of the dangers and be prepared for them.
In general, it is best to avoid flying in areas of known or expected turbulence. If you must fly in turbulent conditions, be sure to buckle your seat belt and remain seated with your seat belt fastened. Keep your seatbelt on at all times during the flight, even if the “fasten seatbelt” sign is not illuminated.
If you are flying in a small aircraft, keep in mind that turbulence can be more severe. Be extra cautious and stay alert for changes in the weather or air conditions.
Listen to the captain’s announcements and follow his or her instructions. If the captain says to brace for impact, do so immediately.
Turbulence can occur at any time during a flight, so always be prepared for it. By following these simple tips, you can make sure that you and your fellow passengers stay safe when flying through turbulent skies.
