AVSC 1100 QUESTIONS AND VERIFIED ANSWERS
What three factors affect the amount of deflection caused by Coriolis force? - Answers -
distance traveled, latitude, speed of the object
Which of the following are true of the atmospheric convection process. - Answers - cool,
heavy air tends to sink and replace warmer, rising air
as air is heated, it expands and becomes less dense than the surrounding air
as air cools, its molecules become packed more closely together, making it denser and
heavier than warm air
Closely spaced isobars on a weather map is an indicator of light surface winds -
Answers - FALSE
What is the average rate of temperature change associated with a change in altitude? -
Answers - 2 degrees C (3.5 degrees F) per 1,000 feet
At what height above the ground would you expect to find the base of the clouds if the
surface temperature is 65 degrees F and the surface dew point is 56 degrees F? -
Answers - 2,000 feet AGL
Which of the following are true about precipitation? - Answers - precipitation can occur
when water or ice particles grow in size until they can no longer be supported by the
atmosphere
coalescence occurs when initial cloud water droplets are of different sizes and larger
drops fall faster, growing as they collide and capture the smaller ones
precipitation is defined as any form of particles, whether liquid or solid, that fall from the
atmosphere
Stratus clouds, fog, light-to-moderate rain, poor visibility, steadily rising dewpoint -
Answers - Warm front
Towering cumulus clouds, short periods of showers, fair visibility in haze, high dewpoint
- Answers - Cold front
Nimbostratus clouds, light-to-heavy precipitation, poor visibility in precipitation, steady
dewpoint - Answers - Occuluded Font
What kind of turbulence is indicated by the presence of rotor, cap, and lenticular
clouds? - Answers - mountain wave turbulence
What is the most dangerous condition for landing with respect to wingtip vortices? -
Answers - in a light, quartering tailwind
