Review of Advances in Precipitation Enhancement Research
Résumé
This paper provides a summary of the assessment report of the World
Meteorological Organization (WMO) Expert Team on Weather Modification
that discusses recent progress on precipitation enhancement research.
The progress has been underpinned by advances in our understanding of
cloud processes and interactions between clouds and their environment
which, in turn, have been enabled by substantial developments in
technical capabilities to both observe and simulate clouds from the
microphysical to the mesoscale.
We focus on the two cloud types most seeded in the past: winter
orographic cloud systems and convective cloud systems. A key issue for
cloud seeding is the extension from cloud-scale research to water
catchment-scale impacts on precipitation on the ground. Consequently,
the requirements for the design, implementation and evaluation of a
catchment-scale precipitation enhancement campaign are discussed.
The paper concludes by indicating the most important gaps in our
knowledge. Some recommendations regarding the most urgent research
topics are given to stimulate further research.
