In the subject for the JAA ATPL theory, one of the most interesting and critical concepts is the relationship between temperature and the height of the tropopause . While it might seem counterintuitive, the tropopause is significantly higher and much colder over the equator than it is over the poles. Key Atmospheric Highlights
: Virtually all significant weather, including 90% of all water vapor, is contained within the troposphere , the lowest layer of the atmosphere. 050 Meteorology (JAA ATPL theory).pdf
: Over the equator, the tropopause can reach heights of approximately 16 km with temperatures as low as -75°C to -80°C . In contrast, over the poles, it may be as low as 8 km with temperatures around -40°C to -45°C . In the subject for the JAA ATPL theory,
