After a Singapore Airlines flight from London to Singapore was hit by sudden and severe turbulence over Myanmar, a Qatar Airways flight from Doha to Dublin encountered severe turbulence over Turkey. The recent incidents highlight the impact of explosive growth in air traffic and climate change on the occurrence of serious turbulence

Flight-Turbulence: Types and Causes

  • Meaning of Flight-Turbulence:
  • Turbulence is an irregular motion of the air resulting from eddies and vertical currents. It can range from minor bumps to severe disturbances that can affect aircraft control and structure. Turbulence is often associated with fronts, wind shear, and thunderstorms.
  • Effects of Flight-Turbulence:
  • There are different types of turbulence with varying effects:
    • Light turbulence: Causes slight bumps and minor altitude changes.
    • Moderate turbulence: Results in more noticeable altitude and attitude changes but the aircraft remains under control.
    • Severe turbulence: Involves significant and sudden altitude and attitude changes, potentially leading to temporary loss of control.
    • Extreme turbulence: Causes violent aircraft movements and is nearly impossible to control.
  • Causes of Flight-Turbulence:
    • Mechanical turbulence: Arises from friction between air and irregular ground surfaces or man-made structures, creating eddies.
    • Convective or thermal turbulence: Occurs due to rapid rising of hot air and descending of cooler air, generating convective air currents.
    • Frontal turbulence: Results from friction between opposing air masses and warm air lifting along frontal surfaces.
    • Wind shear: Involves changes in wind direction or speed over a distance, such as in temperature inversions or near jet streams.
    • Clear air turbulence (CAT): Sudden and severe turbulence that is challenging to predict or detect, sometimes considered a type of wind shear turbulence.

Impact of Climate Change on Flight-Turbulence

  • Findings of the study:
    • Research suggests that climate change could increase the frequency and severity of turbulence.
  • How can this be claimed?
    • Climate change is strengthening jet streams, leading to more turbulence occurrences.
    • There has been a significant increase in clear air turbulence (CAT) between 1979 and 2020, especially at mid-altitudes.
    • Severe CAT durations over the North Atlantic have risen by over 55% during this period.
  • Future predictions:
    • It is anticipated that severe turbulence will become more common compared to light or moderate turbulence.
    • Not only CAT but other forms of turbulence like mountain wave turbulence and near-cloud turbulence are expected to intensify due to climate change.
