This overview discusses various aviation hazards related to slant visibility and haze as reported by the Met Office. As visibility decreases, particularly when haze layers extend above 2500 meters, pilots must be vigilant about potential challenges like severe turbulence, icing, and strong winds. The phenomenon known as the "Goldfish Bowl Effect" illustrates how higher altitudes can improve visibility but also presents new dangers, such as thunderstorms and variable winds. Enhanced awareness of these conditions is crucial for flight safety.
