Météo fondamentale : master class pour pilotes

Fundamental Meteorology: Masterclass for Pilots By Aldo Sterone ParcoursTech #Meteo #Weather #aviation Meteorology Masterclass — The Energy of the Air: Finally Understanding the Weather for Pilots Many student pilots get stuck on meteorology. Not because it's complicated, but because they skip the fundamental building block that almost no one talks about: the energy of the air. Once this concept is understood, everything else falls into place naturally. In this video, I revisit meteorology from its physical foundations, building each idea on the previous one: → Why air energy depends on both temperature AND humidity → Latent heat, and why a tropical thunderstorm is much more violent than a storm in cold air → Absolute humidity vs. relative humidity: which to look at, and when → The dew point and reading the temperature/dew point difference → Cooling gradients: 10°C/1000 m in dry air, sometimes 4°C in saturated air → Stability, instability, and conditional instability, with their concrete effects on visibility, turbulence, and cloud formation → Adiabatic expansion, illustrated by the story of a submarine A deliberately physical and intuitive approach, without indigestible formulas—designed to help those intimidated by meteorology. ⚠️ This video may require multiple viewings: each piece of information is useful later.
