Temperature Flashcards
The presence of wet snow at your flight altitude indicates the freezing level is
above you
If you encounter wet snow at your altitude, this is an indication that the temperature is
above freezing at your altitude.
How much colder than standard temperature is the forecast temperature at 9,000 feet, as indicated in the following excerpt from the Winds and Temperature Aloft Forecast?
7*C
The most frequent type of ground- or surface-based temperature inversion is that produced by
radiation on a clear, relatively still night.
If the air temperature is +8*C at an elevation of 1,350 feet and a standard (average) temperature lapse rate exists, what will be the approximate freezing level?
5,350 feet MSL.
Which weather conditions should be expected beneath a low-level temperature inversion layer when the relative humidity is high?
Smooth air and poor visibility due to fog, haze, or low clouds
Weather variation results from
heating over the earth’s surface
What would the temperature be at 8,000 feet MSL under standard conditions?
-1*C.
When departing from an airport at sea level on a standard day, what temperature would you expect at 9,000 feet MSL?
-3*.
A temperature inversion will normally form only
In stable air.
If the forecast is for a temperature of -2C and a dew point of -3C, what weather can you expect?
Formation of Frost.
You are cruising in rain, with a flight level temperature a few degrees above freezing. You can expect
possible structural icing.
After takeoff, you encounter warmer outside air temperature at 2,000 feet AGL and some turbulence. What is a possible cause of the turbulence?
Temperature inversion.
During climb out after takeoff, you encounter light turbulence at 3,000 feet AGL before entering smooth air. You notice the OAT is warmer than it was at ground level. This indicates
a Temperature inversion.
Which is a characteristic of low-level wind shear as it relates to low level temperature inversions?
Allow airspeed to go above normal climb and approach speed.
