What causes wind to flow around high and low pressure systems?
Wind circulates due to pressure gradients and is deflected by the Coriolis effect, resulting in clockwise flow around highs and counterclockwise around lows in the Northern Hemisphere.
What does a METAR report provide to pilots?
METARs are aviation weather observations that provide current conditions such as wind, visibility, temperature, dew point, and cloud cover.
Which weather phenomenon is most hazardous during landing?
Wind shear is a sudden change in wind speed or direction and can significantly affect aircraft performance during takeoff or landing.
What does a SIGMET alert pilots to?
A SIGMET (Significant Meteorological Information) warns pilots of severe weather conditions such as turbulence, icing, and volcanic ash that could affect flight safety.
What indicates potential aircraft icing conditions?
When the aircraft flies through visible moisture and temperatures are at or below freezing, the risk of icing increases.
What causes a temperature inversion in the atmosphere?
A temperature inversion occurs when a layer of warm air traps cooler air near the surface, often leading to poor visibility and stable air.
