Essentials of Meteorology: Becoming an Excellent Weather Forecaster

This lecture focuses on the key components of becoming an excellent meteorologist. It explores the differences between a decoder and an interpreter, highlights the importance of optimizing efficiency, and emphasizes the need for outstanding data interpretation skills. Attendees will learn how to define problems, assess key observations, and analyze weather patterns through various atmospheric concepts such as shortwaves, ascent types, and precipitation relationships. Practical examples and tools will be discussed to enhance forecasting skills.

Presentation Transcript

  1. Meteo 415 The Lecture Component

  2. Today’s Objectives • What makes an excellent forecaster?

  3. Excellent Forecasters, 2008 • Outstanding data interpreter • Decoder vs. interpreter • Stellar tool box • Optimizes efficiency • Defines problem • Looks at Observations!

  4. Decoder vs. Interpreter What are the differences between the two?

  5. Defining the problem http://www.meteo.psu.edu/~nytwx • Where? • Point or region? • When? • Short or long term? • What? • Temp (hi, low?) • Wind (instantaneous, peak gust?) • Humidity • Precip (amount, type, timing?) • Cloud (amount, type, timing?)

  6. Looks at Observations! http://www.meteo.psu.edu/~nytwx Critical clues! • Excellent forecasters find clues • Examples: • Thunderstorm outflows • Lake-effect snow • Daytime high temperatures

  7. “Weather” can be explained by:“w” http://www.meteo.psu.edu/~nytwx • Shortwaves • Ascent (pva) • Descent (nva) • Fronts • Cyclones (lows), anticyclones (highs) • Buoyancy

  8. Dynamic Ascent: Shortwaves Aloft: 500mb Relationship to Surface

  9. Mechanical Ascent: Frontal lift

  10. Buoyant Ascent: Convection Lifted Index Assesses Instability- how?

  11. Relating upper levels to surface: Real case 500mb heights/vorticity 1000-500 thick/SLP How do I rate shortwave intensity ? http://www.meteo.psu.edu/~nytwx

  12. Relating shortwaves to precipitation patterns 500mb heights “Observed” precip

  13. Relating surface fronts to precipitation patterns Observed precip 1000-500 thick/SLP What’s causing Gulf precip?

  14. Relating 500mb to Cloud Patterns 500mb heights Satellite picture What kind of satellite picture is this?
