Answer

A westerly jet stream at low latitudes in the summer

Answer

A jet stream, with great spacing between the isotherms

Question 5

Answer

Drizzle

Answer

Haze

Answer

Low stratus

Question 9

An isohypse (contour)

Accepted Answer

Indicates the true altitude of a pressure level

Answer

Indicates the altitude of the zero degree isotherm

Answer

Is the limit between two air masses of different temperature

Answer

Is the longest slope line of a frontal surface

Question 10

An aircraft is flying over the sea at FL 120, with a true altitude of 12000 feet

Accepted Answer

Local QNH is 1013 hPa. What assumption, if any, can be made about the air mass in which the aircraft is flying ?

Answer

Its average temperature is the same as ISA

Answer

There is insufficient information to come to any conclusion

Answer

It is warmer than ISA
