  1. MET 2204METEOROLOGY Presentation 2: Introduction to Meteorology Presented by Mohd Amirul for AMC

  2. Learning Outcomes • At the end of this session, student should be able to: • Appreciate the significance of meteorology in the world of aviation. • Get some idea and overview regarding meteorology. Presented by Mohd Amirul for AMC

  3. What is METEOROLOGY?? Presented by Mohd Amirul for AMC

  4. Definition of Meteorology Derived from Greek words: Meteoron – ‘high in the sky’ Logos – ‘knowledge’ • The branch of science dealing with the earth’s atmosphere and the physical process occurring in it. • Its Including moisture, temperature, cloud coverage, pressure, and other meteorological conditions. Presented by Mohd Amirul for AMC

  5. Cont. • Meteorologist: Scientists who study the atmosphere. They examine its effects on the environment, predict the weather, or investigate climate trends. Presented by Mohd Amirul for AMC

  6. So what is the atmosphere?? Presented by Mohd Amirul for AMC

  7. The Atmosphere • layer of gases surrounding the planet Earth that is retained by Earth's gravity. • The earth’s atmosphere • variesvertically and • Horizontally in: • Pressure • Temperature • Density • Humidity Presented by Mohd Amirul for AMC

  8. Is air the same as atmosphere? Presented by Mohd Amirul for AMC

  9. air usually refers to atmosphere that is breathable to us, while atmosphere is any pressurized gas environment. So is there any air and/or atmosphere in other planet?? Presented by Mohd Amirul for AMC

  10. Presented by Mohd Amirul for AMC

  11. Importance of Meteorology in Aviation • Aviation meteorology deals with the impact of weather on air traffic management. • Overall climatic weather conditions to be faced by an aviator with changing of seasons. • Knowing the potential weather to ensure flight journey safely. Presented by Mohd Amirul for AMC

  12. What’s the difference between weather and climate? Presented by Mohd Amirul for AMC

  13. Presented by Mohd Amirul for AMC

  14. Basic concept of Weather • Why there are variation in temperature for every regions? • Earth’s equatorreceived more solar radiation than earth’s poles. So it warmer than poles. • Why there are variation in weather? • Temperature difference results because land and water (different medium) don’t absorb solar radiation equally. • So, warm air and cold air mixing in atmosphere result changing of weather. Presented by Mohd Amirul for AMC

  15. Cont. • What caused of wind flow? • Difference in pressure in atmosphere. • Air tend to move from area of high pressure to low pressure. Presented by Mohd Amirul for AMC

  16. How Weather can be Hazardous to Aviation? 1. Turbulence/Windshear - bumpiness in flight - structural damage to an aircraft - lose of altitude 2. Icing - change in flight performance - increase in weight and uneven loading. - engineintakes become blocked - control surfaces jam Presented by Mohd Amirul for AMC

  17. Cont. 3. Thunderstorms / lightning - Can caused electrical/electronic systems failure - Affect radio communications and navigation equipment 4. Heavy rain / hail - reduction of visibility - affect braking and possible sliding off the runway -hail can affect the aircraft’s aerodynamics - hail can damage propeller and engine blades Presented by Mohd Amirul for AMC

  18. Cont. 5. Snow - affect the airflow into the engines - affect braking action - disturbing the aerodynamics & weight of the aircraft - resultant error of the airspeed and altitude indication -visibility 6. Fog/Mist - degrade the visibility that affected the landing. 7. Low cloud/Poor visibility - can caused collision Presented by Mohd Amirul for AMC

  19. Statistics of Air Disaster caused by Weather Problem Presented by Mohd Amirul for AMC

  20. Causes of Fatal Accidents by Decade (percentage) Presented by Mohd Amirul for AMC

  21. Percent ofAccidentswith Known Causes Presented by Mohd Amirul for AMC

  22. Example of Air Disaster Caused by Weather Presented by Mohd Amirul for AMC

  23. Pan Am Flight 759July 9th , 1982 • Encountered severe windshear and descended into a residential area. • The aircraft crashed on takeoff from runway 10 at New Orleans International Airport • 153 people were killed (145 passengers and crew on board and 8 on the ground) Boeing 727 Presented by Mohd Amirul for AMC

  24. Buffalo Air CrashFebruary 12th , 2009 • The aircraft, on a scheduled passenger flight from Newark, crashed while on approach to the Buffalo/Niagara International Airport • Snow and haze conditions, and ice on the windshield and leading edge of the wings. • All 49 persons aboard the plane were killed, as well as one man on the ground Bombardier Dash 8Q-400 N200WQ Presented by Mohd Amirul for AMC

  25. Conclusion • Meteorology is the scientific study of the atmosphere that focuses on weatherprocesses and forecasting. • Meteorology has application in many diverse fields such as the military, energy production, transport, agriculture and construction. Presented by Mohd Amirul for AMC

  26. Cont. • FOO should have sufficient knowledge and skill to interpret and predict meteorological information efficiently. • They must use this information to ensure flight journey safety. Presented by Mohd Amirul for AMC

  27. Key Points • Definition of Meteorology • Different between weather and climate • Importance of Meteorological in Aviation Presented by Mohd Amirul for AMC

  28. End of Presentation #2 5 Minutes for Q/A session Presented by Mohd Amirul for AMC

  29. Task: • Do some research and study regarding next topic: Atmosphere Presented by Mohd Amirul for AMC

  30. Quote of the Day • Sunshine is delicious, rain is refreshing, wind braces us up, snow is exhilarating; there is really no such thing as bad weather, only different kinds of good weather =) ~John Ruskin Presented by Mohd Amirul for AMC
