SUMMARY:Influences of microphysical processes on atmospheric humidity: obs
 ervations and model results - Dr Jonathon Wright\, University of Cambridge
DTSTART:20110131T141500Z
DTEND:20110131T151500Z
UID:TALK29535@talks.cam.ac.uk
CONTACT:Dr Alex Archibald
DESCRIPTION:The success of simple advection-condensation models at simulat
 ing the distribution of atmospheric water vapor indicates that that distri
 bution is primarily controlled by the large-scale temperature and circulat
 ion. This suggests in turn that the influence of microphysical effects is 
 small - but how small? In particular\, can condensate evaporation be safel
 y neglected\, and in what circumstances? Do local effects such as supersat
 uration play an important role globally? This talk will summarize three pr
 ojects aimed at providing additional constraints on these problems\, using
  both satellite observations and model results. Particular attention will 
 be paid to the tropical upper troposphere\, subtropical dry zones\, and tr
 oposphere-to-stratosphere transport.
