Aerodynamic contrails: Microphysics and optical properties
Aerodynamic contrails form when air flows across the wings of subsonic aircraft in cruise. During a short adiabatic expansion phase, high supersaturations trigger burst-like homogeneous ice formation on ambient liquid aerosol particles within a wing depth. Small particles freeze first, because they equilibrate most rapidly. Ambient temperature is the key determinant of nascent aerodynamic contr...

متن کاملOn the regional climatic impact of contrails: microphysical and radiative properties of contrails and natural cirrus clouds
The impact of contrail-induced cirrus clouds on regional climate is estimated for mean atmospheric conditions of southern Germany in the months of July and October. This is done by use of a regionalized onedimensional radiative convective model (RCM). The in ̄uence of an increased ice cloud cover is studied by comparing RCM results representing climatological values with a modi®ed case. In order...
متن کاملA methodology for in-situ and remote sensing of microphysical and radiative properties of contrails as they evolve into cirrus
Contrails and especially their evolution into cirruslike clouds are thought to have very important effects on local and global radiation budgets, though are generally not well represented in global climate models. Lack of contrail parameterisations is due to the limited availability of in situ contrail measurements which are difficult to obtain. Here we present a methodology for successful samp...
متن کاملBlack carbon radiative heating effects on cloud microphysics and implications for the aerosol indirect effect: 2. Cloud microphysics
This work examines the effect of black carbon (BC) radiative heating on cloud droplet formation. Changes in cloud droplet concentration and cloud albedo due to the presence of black carbon are computed for different cases of aerosol size distributions, meteorological conditions, BC mixing state, and aerosol composition. We examine the effect of three new mechanisms (that result from BC heating)...
