Frozen dew is. White and opaque. Hard and opaque. Hard and transparent.

What will be the wind and temperature trend for an STL MEM MSY flight at FL 330. Windspeed decrease. Wind shift from west to north. Temperature increase 5°C.

Data that may be added (manual weather augmentation) to the Automated Weather Observing System (AWOS) report is limited to. The precipitation accumulation report, an automated variable visibility, and wind direction remark. Thunderstorms (intensity and direction), precipitation (type and intensity), and obstructions to visibility (dependent on the visibility being 3 miles or less). Density Altitude, Notams, and reported slant range visibility.

At lower levels of the atmosphere, friction causes the wind to flow across isobars into a low because the friction. Decreases windspeed and Coriolis force. Decreases pressure gradient force. Creates air turbulence and raises atmospheric pressure.

What is indicated about an air mass if the temperature remains unchanged or decreases slightly as altitude is increased?. The air is unstable. A temperature inversion exists. The air is stable.

Which term applies when the temperature of the air changes by compression or expansion with no heat added or removed?. Katabatic. Advection. Adiabatic.

What weather improvement was reported al Lubbock (KLBB) between 1750 and 1818 UTC?. The wind shift and frontal passage at 1812z. The vertical visibility improved by 2,000 feet. The temperature and dewpoint spread improved.

Which type wind flows downslope becoming warmer and dryer?. Land breeze. Valley wind. Katabatic wind.

What weather is predicted by the term VCTS in a terminal aerodrome forecast?. Thunderstorms are expected in the vicinity. Thunderstorms may occur over the station and within 50 miles of the station. Thunderstorms are expected between 5 and 25 miles of the runway complex.

Which type cloud is associated with violent turbulence and a tendency toward the production of funnel clouds?. Cumulonimbus mammatus. Standing lenticular. Stratocumulus.

You are approaching an airport to land in 20 minutes. The METAR reports temperature 10 degrees C, winds 310/04, scattered clouds and rain. You expect. Radiation fog. Deepening fog. Clearing conditions.

What will be the wind and temperature trend for an SAT ELP TUS flight at 16,000 feet?. Temperature decrease slightly. Windspeed decrease. Wind direction shift from southwest to east.

If squalls are reported at the destination airport, what wind conditions exist?. Sudden increases in windspeed of at least 15 knots, to a sustained wind speed of 20 knots, lasting for at least 1 minute. A sudden increase in wind speed of at least 16 knots, the speed rising to 22 knots or more for 1 minute or longer. Rapid variation in wind direction of at least 20° and changes in speed of at least 10 knots between peaks and lulls.

Which is an effect of ice, snow, or frost formation on an airplane?. Decreased stall speed. Decreased pitchup tendencies. Decreased angle of attack for stalls.

Isobars on a surface weather chart represent lines of equal pressure. at the surface. reduced to sea level. at a given atmospheric pressure altitude.

What method was used to obtain the METAR at Tyler (KTYR) at 1753z?. Automated Surface Observing System (ASOS), having a precipitation discriminator. Automatic Meteorological Observing station (AMOS), with a precipitation discriminator. Automated weather Observing System (AWOS), without a precipitation discriminator.
