met-atmosphere FQ

How does the height of the tropopause normally vary with latitude in the

Northern Hemisphere?

• increases from south to north

• It remains constant throughout the year

• It decreases from south to north

• It remains constant from north to south

A temperature of +15°C is recorded at an altitude of 500 metres above mean

sea level. If the vertical

temperature gradient is that of a standard atmosphere, what will be the

temperature at the summit

of a mountain 2500 metres above mean sea level?

• -2°C

• +4°C

• +2°C

• 0°C

What, approximately, is the average height of the tropopause over the

Equator?

• 8 km

• 16 km

• 11 Km

• 50 Km

In relation to the total weight of the atmosphere, the weight of the

atmosphere

between mean sea level and a height of 5500 m is approximately:

• 99%

• 50%

• 25%

• 1%

In the International Standard Atmosphere the decrease in temperature with

height

below 11 km is:

• 1°C/100 m

• 0.65°/100 m

• 0.6°C/100 m

• 0.5°C/100 m

In the mid-latitudes the stratosphere extends on average from:

• 0 to 11 km

• 11 to 50 km

• 50 to 85 km

• 11 to 20 km

The 200 hPa pressure altitude level can vary in height. In temperate regions

which

of the following average heights is applicable?

• FL300

• FL50

• FL100

• FL390

The international standard atmosphere (ISA) assumes that the temperature

will reduce at a rate of:

• 1.98°C per 1000 feet up to 36 090 feet and then will rise at 0.3°C per 1000

  feet up to 65 617 feet

• 1.98°C per 1000 feet up to 36 090 feet after which it remains constant

  to 65 617 feet

• 2°C per 1000 feet up to 65 617 feet after which it will remain constant to 104

  987 feet

• 2°C per 1000 feet up to 36 090 feet and will then increase at 0.3°C per 1000

  feet up to 65 617 feet

The temperature at FL110 is -12°C. What will the temperature be at FL140 if

the

ICAO standard lapse rate is applied?

• -15°C

• -6°C

• -18°C

• -9°C

Between mean sea level and a height of 20 km the lowest temperature in

the international standard

atmosphere (ISA) is:

• -56.5°C

• -273°C

• -100°C

• -44.7°C
