This final report includes five reprints and preprints of papers associated with the modeling of cloud/radiation processes for large-scale clouds and tropical anvils. These papers present (1) a three-dimensional large-scale cloud model for testing the role of radiative heating and ice phase processes, (2) parameterization of the radiative properties of cirrus clouds, (3) discussion of the scattering and absorption properties of ice crystals in relation to numerical modeling, (4) improvements ...
Satellite imagery suggests that large portions of the tropics are covered by extensive cirrus cloud systems. Tropical cirrus clouds evolve during the life cycle of the mesoscale convective systems and are modulated by large- scale disturbances. Outflow cirrus clouds from tropical cumulonimbi appear to be maintained in a convectively active state by radiative flux gradients within the clouds, as suggested by Danielson (1982). Extensive anvils are likely to become radiatively ...
