Light turbulence always has to be expected... above cumulus clouds due to thermal convection. below stratiform clouds in medium layers. when entering inversions. below cumulus clouds due to thermal convection.
Moderate to severe turbulence has to be expected... with the appearance of extended low stratus clouds (high fog). overhead unbroken cloud layers. below thick cloud layers on the windward side of a mountain range. on the lee side of a mountain range when rotor clouds are present.
Which answer contains every state of water found in the atmosphere? Liquid and solid Liquid, solid, and gaseous Gaseous and liquid Liquid
.
How do dew point and relative humidity change with decreasing temperature? Dew point remains constant, relative humidity decreases Dew point decreases, relative humidity increases Dew point increases, relative humidity decreases Dew point remains constant, relative humidity increases.
How do spread and relative humidity change with increasing temperature? Spread increases, relative humidity decreases Spread remains constant, relative humidity decreases Spread increases, relative humidity increases Spread remains constant, relative humidity increases.
The "spread" is defined as... relation of actual to maximum possible humidity of air. maximum amount of water vapour that can be contained in air. difference between dew point and condensation point. difference between actual temperature and dew point.
With other factors remaining constant, decreasing temperature results in... decreasing spread and decreasing relative humidity. increasing spread and decreasing relative humidity. increasing spread and increasing relative humidity. decreasing spread and increasing relative humidity.
What process causes latent heat being released into the upper troposphere? Descending air across widespread areas Stabilisation of inflowing air masses Cloud forming due to condensation Evaporation over widespread water areas.
The saturated adiabatic lapse rate is... lower than the dry adiabatic lapse rate. proportional to the dry adiabatic lapse rate. higher than the dry adiabatic lapse rate. equal to the dry adiabatic lapse rate.
The dry adiabatic lapse rate has a value of... 1,0° C / 100 m. 2° / 1000 ft. 0,6° C / 100 m. 0,65° C / 100 m.
The saturated adiabatic lapse rate should be assumed with a mean value of: 1,0° C / 100 m. 0° C / 100 m. 0,6° C / 100 m. 2° C / 1000 ft.
