Convert 15 degree Celsius to Fahrenheit temperature. - Answer- 59F Standard lapse rate is about ______ degrees C per 1000 feet. - Answer- 2 The most frequent type of ground or surface based temperature inversion is that which is produced by - Answer- the movement of colder air under warm air, or the movement of warm air over cold air Moisture is added to air by - Answer- Evaporation and sublimation T/F Relative humidity indicate the actual water contents instead of how close the air is to saturation, so relative humidity is always constant regardless of temperature. - Answer- FALSE T/F The higher the air parcel's temperature is, the greater the air parcel's capacity of holding water will be. - Answer- TRUE Assuming constant pressure, temperature, and volume, which statement is correct? -air with greater amount of water vapor is more dense (weigh more) than air with lesser amount of water vapor. -air with greater amount of water vapor is less dense (weigh less) than air with lesser amount of water vapor -air with greater amount of water vapor has same density (weigh same) as air with lesser amount water vapor. - Answer- air with greater amount of water vapor is less dense (weigh less) than air with lesser amount of water vapor A temperature inversion would most likely result in which weather condition ? - Answer- An increase in temperature as altitude is increased The difference between an air parcel's temperature and its dewpoint is the dewpoint depression, or commonly referred to as the spread. When the spread decreases to zero : - Answer- relative humidity is 100 percent Select the phase transition that is not associated with the absorption of latent heat: melting evaporation sublimation freezing - Answer- FREEZING What is incorrect statements about density -Assuming equal mass, an air parcel with a higher density has a smaller volume than an air parcel with a lower density -Assuming constant mass and temperature, an air parcel with a higher pressure is denser than an air parcel with a lower pressure. -Assuming constant mass and pressure, an air parcel with a higher temperature is less dense than an air parcel with a lower temperature -Assuming constant pressure, temperature, and volume, air with a greater amount of water vapor is more dense than air with a lesser amount of water vapor. - Answer- Assuming constant pressure, temperature, and volume, air with a greater amount of water vapor is more dense than air with a lesser amount of water vapor. T/F In the cold air column, the pilot would fly at an altitude lower than the indicated altitude. - Answer- TRUE Every physical process of weather is accompanied by, or is the result of, a - Answer- Heat exchange Clouds, fog, or dew will always form when - Answer- water vapor condenses Which is true regarding actual air temperature and dewpoint temperature spread? the temperature spread - Answer- decreases as the relative humidity increases. T/F On Density altitude - dewpoint (water vapor) is also contributing factor, but its effects are generally negligible. - Answer- FALSE The wind at 5,000 feet AGL is southwesterly while the surface wind is southerly. The difference in direction is primarily due to - Answer- friction between the wind and the surface The performance table of an aircraft for takeoff and climb are based on - Answer- pressure/density altitude Convective circulation patterns associated with sea breezes are caused by - Answer- Cool, dense air moving inland from over the water Select incorrect statement. -Cold Front - colder air replace warm air -Warm Front - warmer air is replaced by colder air -Stationary Front - a front which is stationary or near so -Occluded Front - A composite of two front as a cold front takes a warm front or stationary front - Answer- Warm Front - warmer air is replaced by colder air One weather phenomenon which will always occur when flying across a front is a change in the - Answer- PRESSURE 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 - Answer- 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? - Answer- 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 - Answer- 10,000FT What is Moist adiabatic lapse rate ? - Answer- varies between 1.2 to 3 degree C per 1000 feet what are the characteristics of a moist, unstable air mass? - Answer- Cumuliform cloud and showery precipitation. A stable air mass is most likely to have which characteristic? - Answer- Poor surface visibility If an unstable air mass is forced upward, what type clouds can be expected? - Answer- Clouds with considerable vertical development and associated turbulence. What is average dry adiabatic lapse rate? - Answer- 3 degree C/ 1000 feet What measurement can be used to determine the stability of the atmosphere? - Answer- Actual lapse rate What would decrease the stability of an air mass? - Answer- Warming from below
