Effects of cirrus near the tropopause on anvil cirrus dynamics
[1] Recent space and airborne observations have noted tenuous cirrus near the tropopause and above deep convective anvil outflow. We use a cloud-resolving model, initialized with aircraft observations taken during the CRYSTAL-FACE experiment, to explore the effects of such cirrus layers on anvil evolution. Numerical simulations demonstrate that anvil cirrus spreads because strong absorption of ...
متن کاملConvective generation of cirrus near the tropopause
[1] During the July 2002 CRYSTAL-FACE field program based from Key West, Florida, aircraft measurements showed that long-lived thin tropopause cirrus (TTC) layers were often present above thunderstorm anvils. This paper describes these clouds and explores their possible origins. Measurements showed that the horizontal dimensions of TTC layers were nearly identical to convectively formed anvils ...
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 کاملMaintenance of tropical tropopause layer cirrus
5 [1] A two-dimensional cloud resolving model with explicit bin microphysics is used to 6 study the maintenance of tropical tropopause layer (TTL) cirrus. Numerical simulations 7 using this model show that a TTL cirrus with a maximum radiative heating rate of 3 K/day 8 is able to self-maintain for as long as 2 days if it contains ice crystals whose initial 9 mean radius is smaller than about 5 ...
متن کاملSatellite observations of cirrus clouds in the Northern Hemisphere lowermost stratosphere
Here we present observations of the Cryogenic Infrared Spectrometers and Telescopes for the Atmosphere (CRISTA) of cirrus cloud and water vapour in August 1997 in the upper troposphere and lower stratosphere (UTLS). The observations indicate a considerable flux of moisture from the upper tropical troposphere into the extratropical lowermost stratosphere (LMS), resulting in the occurrence of hig...
