Contrails and Induced Cirrus
C loud radiative forcing, the difference between the top-of-atmosphere radiative fluxes for all sky and clear skies, is a straightforward metric to gauge the climate impacts of contrails and contrail cirrus, which constitute a potentially serious long-term environmental issue associated with aviation (Minnis et al. 2004; Wuebbles et al. 2010). The Intergovernmental Panel on Climate Change (IPCC...
متن کاملCirrus, contrails, and ice supersaturated regions in high pressure systems at northern mid latitudes
During the European heat wave summer 2003 with predominant high pressure conditions we performed a detailed study of upper tropospheric humidity and ice particles which yielded striking results concerning the occurrence of ice supersaturated regions (ISSR), cirrus, and contrails. Our study is based on lidar observations and meteorological data obtained at Lindenberg/Germany (52.2 N, 14.1 E) as ...
متن کاملSolution coating around ice particles of incipient cirrus clouds.
Kuhs et al. (1) report on the nanometer-scale roughness on the surface of laboratory vapordeposited cubic ice, Ic, and state that such roughness on the surface of cirrus Ic ice particles can influence the surface reactivity, radiative properties, and water vapor uptake coefficient of incipient cirrus clouds. This assumes that the ice surface of cirrus particles is exposed to air. However, this ...
متن کاملPersistent Contrails and Contrail Cirrus. Part II: Full Lifetime Behavior
More than 200 large-eddy simulations of long-lived contrails from several-seconds age until their demise have been performed and their lifetime-integrated behavior has been analyzed. The simulations employ sizeresolved microphysics and include variations of effective ice crystal number emission index, temperature, relative humidity with respect to ice, stratification, shear, supersaturated-laye...
متن کاملLaser vaporization of cirrus-like ice particles with secondary ice multiplication
We investigate the interaction of ultrashort laser filaments with individual 90-μm ice particles, representative of cirrus particles. The ice particles fragment under laser illumination. By monitoring the evolution of the corresponding ice/vapor system at up to 140,000 frames per second over 30 ms, we conclude that a shockwave vaporization supersaturates the neighboring region relative to ice, ...
