Understanding Fog and Precipitation Concepts

The video tutorial from Epic Flight Academy, led by Mike Thompson, covers the topic of fog as part of a private pilot ground school course. It explains how fog forms when temperature and dew point converge, and describes fog as a cloud on the ground. The tutorial discusses four common types of fog: radiation, advection, upslope, and steam fog. Additionally, it touches on types of precipitation, including drizzle, rain, virga, hail, ice pellets, and snow. The video emphasizes the importance of understanding these concepts for successful pilot training.

What does the term 'fog burning off' refer to in aviation?

• Temperature rising and fog dissipating

• Fog being blown away by wind

• Fog turning into rain

• Fog catching fire

Which two factors are necessary for fog to form?

• Wind speed increasing and temperature decreasing

• Temperature decreasing and dew point increasing

• Temperature rising and humidity decreasing

• Humidity decreasing and dew point decreasing

How is fog similar to clouds?

• Fog and clouds both form only at high altitudes

• Fog and clouds are both formed by wind

• Fog is made of ice crystals like clouds

• Fog is a type of cloud that forms on the ground

What is radiation fog and when does it typically occur?

• Fog that forms during heavy rainfall

• Fog that forms on clear, calm, humid nights

• Fog that forms over oceans during storms

• Fog that forms in mountainous regions

Which type of fog is caused by warm moist air moving over cooler land?

• Advection fog

• Radiation fog

• Steam fog

• Upslope fog

What causes upslope fog to form?

• Warm air rising over a mountain

• Moist stable air being forced up a slope

• Cold air descending into a valley

• Dry air moving over a warm surface

What is virga in terms of precipitation?

• Rain that evaporates before reaching the ground

• Snow that melts before hitting the ground

• Hail that forms in warm air

• Drizzle that turns into snow

How do ice pellets differ from hail?

• Ice pellets form from melted snow that refreezes

• Ice pellets are larger than hail

• Ice pellets form in warm clouds

• Ice pellets are softer than hail

What is the primary difference between drizzle and rain?

• Drizzle is heavier than rain

• Drizzle occurs only in winter

• Drizzle is lighter and has smaller droplets than rain

• Drizzle is made of ice, rain is liquid

What are the two main conditions that lead to fog formation?

• Temperature rising and humidity decreasing

• Humidity decreasing and dew point decreasing

• Temperature decreasing and moisture content increasing

• Wind speed increasing and temperature rising
