Continuous updraft. Frequent lightning. Beginning of rain at the surface. 2 / 10 Convective clouds which penetrate a stratus layer can produce which threat to instrument flight? Clear air turbulence. Embedded thunderstorms. Freezing rain. 3 / 10 If the ambient temperature is colder than standard at FL 310, what is the relationship between true altitude and pressure altitude? They are both the same, 31,000 feet. True altitude is lower than 31,000 feet. Pressure altitude is lower than true altitude. 4 / 10 What characterizes a ground-based inversion? Poor visibility. Cold temperatures. Convection currents at the surface. 5 / 10 What condition produces the most frequent type of ground- or surface-based temperature inversion? Terrestrial radiation on a clear, relatively calm night. The movement of colder air under warm air or the movement of warm air over cold air. Widespread sinking of air within a thick layer aloft resulting in heating by compression. 6 / 10 How can the stability of the atmosphere be determined? Surface temperature/dewpoint spread. Ambient temperature lapse rate. Atmospheric pressure at various levels. 7 / 10 What weather condition occurs at the altitude where the dewpoint lapse rate and the dry adiabatic lapse rate converge? Stable air changes to unstable air. Precipitation starts. Cloud bases form. 8 / 10 Which event usually occurs after an aircraft passes through a front into the colder air? Temperature/dewpoint spread decreases. Atmospheric pressure increases. Wind direction shifts to the left. 9 / 10 What is a characteristic of the troposphere? There is an overall decrease of temperature with an increase of altitude. It contains all the moisture of the atmosphere. The average altitude of the top of the troposphere is about 6 miles. 10 / 10 What is the primary cause of all changes in the Earth’s weather? Movement of air masses from moist areas to dry areas. Variations of solar energy at the Earth’s surface. Changes in air pressure over the Earth’s surface.

Indicated airspeed decreases, aircraft pitches down, and altitude decreases. Indicated airspeed decreases, aircraft pitches up, and altitude decreases. Indicated airspeed increases, aircraft pitches down, and altitude increases. 2 / 10 What is an important characteristic of wind shear? It usually exists only in the vicinity of thunderstorms, but may be found near a strong temperature inversion. It may be associated with either a wind shift or a windspeed gradient at any level in the atmosphere. It is primarily associated with the lateral vortices generated by thunderstorms. 3 / 10 Which type precipitation is an indication that supercooled water is present? Wet snow. Freezing rain. Ice pellets. 4 / 10 What is a feature of supercooled water? The temperature of the water drop remains at 0°C until it impacts a part of the airframe, then clear ice accumulates. The unstable water drop freezes upon striking an exposed object. The water drop sublimates to an ice particle upon impact. 5 / 10 Which conditions result in the formation of frost? The temperature of the collecting surface is at or below freezing and small droplets of moisture are falling. Temperature of the collecting surface is below the dewpoint and the dewpoint is also below freezing. Dew collects on the surface and then freezes because the surface temperature is lower than the air temperature. 6 / 10 What temperature condition is indicated if precipitation in the form of wet snow occurs during flight? The temperature is above freezing at flight altitude. The temperature is above freezing at higher altitudes. There is an inversion with colder air below. 7 / 10 Freezing rain encountered during climb is normally evidence that a layer of warmer air exists above. ice pellets at higher altitudes have changed to rain in the warmer air below. a climb can be made to a higher altitude without encountering more than light icing. 8 / 10 Where can the maximum hazard zone caused by wind shear associated with a thunderstorm be found? In front of the thunderstorm cell (anvil side) and on the southwest side of the cell. Ahead of the roll cloud or gust front and directly under the anvil cloud. On all sides and directly under the thunderstorm cell. 9 / 10 Where do squall lines most often develop? Behind a stationary front. In an occluded front. Ahead of a cold front. 10 / 10 Which weather phenomenon signals the beginning of the mature stage of a thunderstorm? The appearance of an anvil top. The start of rain at the surface. Growth rate of the cloud is at its maximum. Your score isThe average score is 0% 0% Restart quiz
