Turbulence in the skies is a phenomenon that can turn a smooth flight into a bumpy ride, causing concern for both air crew and passengers. This informative blog post probes into the various levels of turbulence, the potential risks it poses, and the factors that contribute to its occurrence. From light turbulence causing seatbelt strain to extreme turbulence leading to structural damage, the dangers of air turbulence are explained to help readers understand and navigate this unpredictable aspect of air travel.
What is Turbulence and What Causes It?
Definition of Turbulence
Any air traveler knows the sensation – the sudden jolts, the unexpected bumps, the feeling of being tossed around in your seat. This phenomenon is known as turbulence. But what exactly is turbulence, and what causes it?
Four Main Levels of Turbulence
Definition: Turbulence in the skies can be categorized into four main levels – light, moderate, severe, and extreme. While light and moderate turbulence may simply result in some strain against your seatbelt, severe turbulence can lead to passengers being thrown around the cabin, potentially causing serious injuries or even fatalities.
This classification of turbulence levels helps air crews and passengers understand the potential impact of turbulence during flights, allowing for better preparation and safety measures.
Causes of Turbulence
To comprehend turbulence, it’s important to explore its root causes. Turbulence on flights can be triggered by various factors like storms, mountains, and strong air currents known as jet streams. One common form, clear-air turbulence, can be particularly dangerous as it doesn’t show up on weather radar, making it challenging to anticipate.
Four air movement drivers, including atmospheric pressure, jet streams, air around mountains, and weather fronts, can lead to turbulence. Pilots receive warnings about potential turbulence, but instances can still arise unexpectedly, highlighting the unpredictability and risk turbulence poses to air travel.
How Turbulence Affects Flights
