Some Synoptic Effects Of Long-Wave Radiation From Cloud-Top
Abstract
Calculations with a synoptic case study show that long-wave
radiative cooling tends to reduce the available potential energy,
especially in the upper troposphere. Synoptic-scale precipitation
amounts resulting from destabilization of clouds by long-wave cooling
are computed. These range up to 1.4 mm in 12 hours. This destabilizing
effect may be important in explaining the nocturnal maximum
of precipitation over the sea. It may also contribute significantly to
cyclone development.
