A Parameterization of Cirrus Cloud Formation: Revisiting Competing Ice Nucleation
This study develops an advanced physically‐based parameterization of heterogeneous ice nucleation in cirrus clouds that includes an updated parameterization of stochastic homogeneous freezing of supercooled solution droplets. ... -
A Stochastic Representation of Temperature Fluctuations Induced by Mesoscale Gravity Waves
Ubiquitous mesoscale gravity waves generate high cooling rates important for cirrus formation. We make use of long-duration balloon observations to devise a probabilistic model describing mesoscale temperature uctuations ... -
Process-Based Simulation of Aerosol-Cloud Interactions in a One-Dimensional Cirrus Model
A new microphysical cirrus model to simulate ice crystal nucleation, depositional growth, and gravitational settling is described. The model tracks individual simulation ice particles in a vertical column of air and allows ... -
The Role of Mineral Dust Aerosol Particles in Aviation Soot‐Cirrus Interactions
Predicting cirrus cloud properties with confidence requires a sound understanding of the relative roles of homogeneous and heterogeneous ice formation. This study explores the effect of mineral dust and contrail‐processed ...
