likely find favorable winds associated with high- and low-pressure systems by flying to the -
Answer south of a high and to the north of a low
The general circulation of air associated with a high-pressure area in the Northern Hemisphere
is - Answer outward, downward, and clockwise
Which is an operational consideration regarding actual air temperature and dewpoint
temperature spread? - Answer The temperature spread decreases as the relative humidity
increases
The ratio of the existing water vapor in the air, as compared to the maximum amount that could
exist at a given temperature, is called - Answer relative humidity
What is the process by which ice can form on a surface directly from water vapor on a cold,
clear night? - Answer Sublimation

6,500 feet to 23,000 feet
Which middle level clouds are characterized by rain, snow, or ice pellets posing a serious icing
problem if temperature are near or below freezing? - Answer Nimbostratus
Frontal waves normally form on - Answer slow-moving cold fronts or stationary fronts
Cool air moving over a warm surface is generally characterized by - Answer instability and
showers
Which statement is true regarding a cold front occlusion? - Answer The air ahead of the
warm front is warmer than the air behind the overtaking cold front
Tornadoes are most likely to occur with which type of thunderstorms? - Answer Steady-state
thunderstorms associated with cold fronts or squall lines
Which type of cloud is associated with violent turbulence and a tendency toward the
production of funnel clouds? - Answer Cumulonimbus mamma
Radiation fog is most likely to occur under what conditions? - Answer High humidity during
the early evening, cool cloudless night with light winds, and favorable topography
Advection fog is formed as a result of - Answer moist air moving over a colder surface
Fog associated with a warm front is a result of saturation due to - Answer evaporation of
precipitation
