# Singapore Airlines Flight: Turbulence Incident Analysis
Written on
Chapter 1: Overview of the Incident
On May 20th, a Singapore Airlines flight traveling from London to Singapore encountered severe turbulence approximately one hour before its scheduled arrival. The aircraft was over the Andaman Sea or Bay of Bengal when it experienced extreme turbulence, leading to significant internal disarray. Tragically, one passenger lost their life, and numerous others sustained injuries, requiring hospitalization. The flight was ultimately diverted to Thailand instead of landing in Singapore, prompting extensive investigations into the circumstances surrounding the event.
This episode serves as a reminder that turbulence is a common occurrence in air travel. Frequent flyers are likely aware that turbulence can happen on both domestic and international flights, particularly over large bodies of water. Various factors contribute to turbulence, with jet streams being one of the most significant. Additionally, entering large cloud formations can exacerbate turbulence.
Section 1.1: Understanding Turbulence
While turbulence cannot be entirely avoided, pilots receive essential data regarding potential turbulence along their flight path before departure. Announcements regarding expected turbulence are based on this information. Although it is impossible to eliminate turbulence entirely, flight routes can often be adjusted to minimize its impact.
For instance, if forecasters predict severe turbulence in a specific area, like the Andaman Sea, it may be prudent to alter the flight path. Airlines typically strive for the shortest route to conserve fuel and time; however, safety should always take precedence.
Subsection 1.1.1: The Incident's Details
Reports indicate that the aircraft experienced a rapid descent from an altitude of 37,000 feet to approximately 31,000 feet—a drop of about 6,000 feet (or roughly 2 kilometers). Such a sudden change in altitude can trigger emergency protocols, including the deployment of oxygen masks, and can induce panic among passengers.
Section 1.2: Causes of Turbulence
Turbulence is a well-documented atmospheric phenomenon resulting from varying air speeds at different altitudes. Friction between airflows in diverse directions leads to turbulence, which can primarily manifest in two forms:
- Clear Air Turbulence: Often associated with jet streams.
- Cloud-Induced Turbulence: Typically occurs in cumulonimbus clouds, which can generate powerful upward and downward air currents, creating a jarring experience for passengers.
Chapter 2: The Role of Jet Streams
Jet streams, which are high-altitude winds flowing from west to east, significantly contribute to turbulence. These winds, found in the upper troposphere at altitudes between 20,000 and 50,000 feet, develop when air masses of varying temperatures interact. The greater the temperature difference, the more intense the jet stream winds.
There are various types of jet streams, including:
- Subtropical Jet Streams: Common in winter and early spring.
- Tropical Easterly Jet Streams: Found near the tropopause in regions like Southeast Asia, India, and Africa.
- Polar Night Jet Streams: Occurring in polar regions.
Climate Change Impact
Recent studies have shown a correlation between climate change and increased turbulence. Current evidence suggests that instances of severe turbulence in the North Atlantic have risen by 55% since 1979. Projections indicate that turbulence could double or even triple in frequency as climate change continues to escalate.

The second video provides an analysis of what transpired during the Singapore Airlines flight, exploring the causes of the turbulence and its effects.
Technology and Flight Planning
While eliminating turbulence entirely is impossible, advancements in technology allow for better forecasting of turbulent areas. This information can help pilots and dispatchers devise safer flight routes. Dispatchers play a crucial role in gathering data and coordinating flight plans, ensuring the chosen route is both efficient and safe.
