1BL 1 Which environment most likely to form radiation fog?
Clear sky, little or no wind, small temperature/dew point spread, and over a land surface.
2LV If the temperature/dew point spread is 4 degree and decreasing, and the temperature is 62°F, what type weather is most likely to develop?
Fog or low clouds.
3BL 3 Which environment most likely to form advection fog?
The movement of warm moist air over colder ground
4BL. 4 When moist air flows from a relatively warm surface to a colder surface, which condition will be likely happen?
Fog.
5BL 5 where advection fog most likely to form?
Coastal region
6BL 6 What types of fog form with a wind?
Advection fog and up slope fog.
7BL 7 In which case advection fog dissipate or lifted to become low stratus clouds?
Wind 15 knots or more
8BL 8 What is the difference advection fog, radiation fog, and steam fog?
Radiation fog is located on land areas; advection fog is most common along coastal areas; steam fog over a water surface.
9BL 9 Select correct statement about advection fog
It can appear suddenly anytime, and remain over the water for weeks, advancing over the land during night and retreating back over the water the next morning.
10Bl 10 Low-level turbulence and icing may be associated in which type of fog?
Steam fog.
11BLM 11 Fog associated with frontal activity is due to the saturation caused by;
evaporation of precipitation.
12BLM 12 Warm fronts can commonly cause which in flight hazard?
Precipitation-induced fog.
13BL 13. Fog in industrial areas usually caused by?
an abundance of condensation nuclei from industrial combustion
1414 BL Precipitation induced fog
result from warm rain or drizzle falling through cooler air.
1515 BLM On the lee side of a large lake which weather condition may be prevailing?
Warm air flowing over a colder lake may produce fog
1616 BL A flight is scheduled at sunrise. It is rainy now, but are expected to clear soon. The forecast temperature is 8 degree C, dew point 8 degree C, with wind will be calm. What would you expect?
radiation fog.
