: 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 .
: A striking fact for flight planning is that 50% of the atmosphere's total mass is concentrated within the first 5 km (approx. 18,000 ft) of the Earth's surface. 050 Meteorology (JAA ATPL theory).pdf

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 18,000 ft) of the Earth's surface
