Study Notes
TAF and Weather Conditions
- TAF indicates weather forecasting with specific details on wind direction and visibility.
- Example: Wind direction at 240T and visibility of 3 statute miles (SM).
- Temporary conditions (Tempo) are essential to consider in TAF reports.
Coriolis Effect
- The Coriolis effect results from the Earth's rotation around its axis.
- It influences weather patterns and atmospheric circulation.
Thunderstorm Dynamics
- In the disappearing stage of a thunderstorm, down drafts begin to spread out.
- This stage indicates a weakening storm as it loses its updraft strength.
Condensation Process
- Condensation occurs when water vapor in the air cools and transforms into liquid, releasing latent heat.
- Latent heat release plays a crucial role in driving atmospheric processes.
Air Cooling Mechanism
- The primary mechanism for cooling in the atmosphere is adiabatic expansion.
- As air rises, it expands and cools without heat exchange with the environment.
Instrument Landing System (ILS)
- ILS guidance typically moves from full left to full right through an angle of 5 degrees.
- Precision in navigation is necessary for safe landing procedures.
Thunderstorm Conditions
- Severe conditions, including icing and turbulence, increase away from the wave crest during thunderstorms.
- Understanding these conditions is vital for flight safety in stormy weather.
Cold Front Characteristics
- Within a 50 nautical mile (nm) radius ahead of a cold front, expect cloud types such as cumulonimbus (CB) and cumulonimbus scattered (Cu).
- These cloud formations align parallel to the advancing cold front, indicating potential weather changes.
