Study Notes
Pressure Systems and Aviation Weather
- High-pressure systems (anticyclones) have higher atmospheric pressure than their surroundings, associated with calmer weather conditions, clear skies, and lighter winds.
- High-pressure systems can lead to potential hazards like temperature inversions, which trap pollutants and lead to poor visibility conditions.
- Low-pressure systems (cyclones) have lower atmospheric pressure than their surroundings, associated with bad weather, overcast skies, stronger winds, and precipitation.
- Low-pressure systems can pose significant flight safety challenges.
Impact of Pressure Systems on Flight
- High-pressure systems can stir up clear air turbulence, an invisible threat that can occur in cloudless regions under high pressure.
- Low-pressure systems are associated with wind shear, a rapid change in wind direction or speed over a short distance, which can be particularly hazardous during takeoff or landing.
Coriolis Effect
- The Coriolis effect is a force that steers winds and storms around the planet, caused by the Earth's rotation.
- It diverts moving air to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
- The Coriolis effect shapes global wind patterns, including trade winds, jet streams, and hurricanes.
Impact of Coriolis Effect on High and Low-Pressure Systems
- In the Northern Hemisphere, high-pressure systems spin clockwise, and low-pressure systems spin counter-clockwise.
- These rotations direct the weather conditions associated with each system.
Coriolis Effect in Aviation
- Understanding the Coriolis effect is important for flight planning, as it affects fuel management and route safety.
- It helps pilots anticipate weather patterns and make decisions that keep passengers and crew safe.
Atmospheric Circulation and Weather Patterns
- Atmospheric circulation is a key determinant of the world's climate and weather patterns.
- Pressure systems, created by the unequal heating of the Earth's surface, play a crucial role in shaping these patterns.
- The rotation of the Earth introduces the Coriolis effect, causing winds to curve and shaping global wind patterns.
