QUESTIONS AND ANSWERS RATED A+
✔✔Select incorrect statement
-Warm fronts typically have a gentle slope
-Cold fronts have a steep slope
-Typically warm front move faster than cold front and catch up to form a occluded front
-Cold front often forms a narrow band of showers just ahead of or along the front -
✔✔Typically warm front move faster than cold front and catch up to form a occluded
front
✔✔In which meteorological conditions can frontal waves and low pressure area form? -
✔✔Slow-moving cold fronts or stationary fronts.
✔✔At approximately what altitude above the surface would be pilot expect the base of
cumuliform clouds if the surface air temperature is 82F and the dew point is 38F -
✔✔10,000FT
✔✔What is Moist adiabatic lapse rate ? - ✔✔varies between 1.2 to 3 degree C per 1000
feet
✔✔what are the characteristics of a moist, unstable air mass? - ✔✔Cumuliform cloud
and showery precipitation.
✔✔A stable air mass is most likely to have which characteristic? - ✔✔Poor surface
visibility
✔✔If an unstable air mass is forced upward, what type clouds can be expected? -
✔✔Clouds with considerable vertical development and associated turbulence.
✔✔What is average dry adiabatic lapse rate? - ✔✔3 degree C/ 1000 feet
✔✔What measurement can be used to determine the stability of the atmosphere? -
✔✔Actual lapse rate
✔✔What would decrease the stability of an air mass? - ✔✔Warming from below
✔✔What determines the structure or type of clouds which will form as a result of air
being forced to ascend? - ✔✔The stability of the air before lifting occurs
✔✔The formation of either predominantly stratiform or predominantly cumuliform clouds
is dependent upon the - ✔✔stability of air being lifted
, ✔✔When conditionally unstable air with high-moisture content and very warm surface
temperature is forecast, one can expect what type of weather? - ✔✔Strong updrafts and
cumulonimbus clouds
✔✔If clouds form as a result of very stable, most air being forced to ascend a mountain
slope, the clouds will be - ✔✔Stratus type with little vertical development and little or no
turbulence
✔✔Stratus type with little vertical development and little or no turbulence - ✔✔towering
cumulus clouds
✔✔When do Ice pellet (sleet) occur? - ✔✔when there is a shallow layer aloft with above
freezing temperatures and with a deep layer of below freezing air based at the surface.
✔✔When does freezing rain occur? - ✔✔when there is a deep layer aloft with above
freezing temperatures and with a shallow layer of below freezing air at the surface.
✔✔Why do you have to avoid tailwind on take off? - ✔✔to avoid longer take off distance
✔✔What is an important characteristic of wind shear? - ✔✔it can be present at any level
and can exist in both a horizontal and vertical direction
✔✔Hazardous wind shear is commonly encountered in - ✔✔areas of temperature
inversion and near thunderstorms.
✔✔A strong wind shear can be expected - ✔✔On the low-pressure side of a Jetstream
core where the speed at the core is stronger than 110 knots
✔✔Precipitation induced fog - ✔✔Result from relatively warm rain or drizzle falling
through cooler air
✔✔Which condition produces weather on the Lee side of a large lake - ✔✔Warm air
flowing over a colder lake may produce fog
✔✔Flight is scheduled at daybreak. Forecast temperature and dew point is 10 degrees
C. What conditions can you expect - ✔✔Favorable for radiation fog
✔✔Type of turbulence that causes slight, rapid, somewhat rhythmic bumpiness without
changes in altitude or attitude - ✔✔Occasional light chop
✔✔Icing associated with the smallest size of water droplet similar to that found in low
level stratus clouds - ✔✔Rime ice
