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 کاملAtmospheric Electricity and Cloud Microphysics
The terrestrial atmospheric electrical system covers a range of dimensional scales, from charged molecular clusters to convective cloud systems. Charge-exchange associated with thunderclouds leads to positive charge in the upper conductive regions of the atmosphere and a net negative charge on the planetary surface. In non-thunderstorm regions, a vertical ionic current flows, replenishing the a...
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)...
متن کاملGround-Based Cirrus Observation in the Japanese Cloud and Climate Study: A Sonde System for Radiation and Cloud Microphysics Measurement
Clouds play a crucial role in radiative energy budget and water cycle in the earth-atmosphere system. In order to understand processes such as global warming and to improve assessment of climate change, it is necessary to develop climate models which properly take into account radiation and cloud processes. In addition, it is also important to improve satellite monitoring systems for measuring ...
متن کاملEffects of Cloud Parameterization on Radiation and Precipitation: A Comparison Between Single-Moment Microphysics and Double-Moment Microphysics
This study compares a single-moment microphysics scheme to a double-moment microphysics scheme using four observed cases of a mesoscale cloud system. Previous studies comparing a single-moment microphysics scheme to a doublemoment microphysics scheme have focused on microphysical processes or overall dynamics, precipitation and morphology of cloud systems. However, they have not focused on how ...
