The Blanket Effect is intended for others to learn about weather modification and its related subjects in an easy to understand way. Started in 2005, this blog is a work in progress as the technology advances

WMO Toots Its' Own Horn

Physics and Chemistry of Clouds and Weather Modification Research Programme

In 1975, the Seventh World Meteorological Congress adopted a Weather Modification Programme.

Since then WMO has been recognized as the international body with the necessary scientific and technical expertise to respond to requests concerning weather modification.

The name of the programme was later changed to include the physics and chemistry of clouds.

WMO stimulates collaboration and participation in basic research on clouds processes, the Physics and Chemistry of Clouds and Weather Modification Research Programme, and focuses upon the interaction of clouds with the atmosphere.

The focal point of the programme is the WMO Executive Council Panel of Experts/ Commission for Atmospheric Sciences (CAS) Working Group on Physics and Chemistry of Clouds and Weather Modification Research.

The Panel/Working Group keeps under review relevant research and provides advice to the WMO Executive Council, CAS and other bodies on urgent problems related to physics and chemistry of clouds and weather modification research.

The main objective of the Programme on Physics and Chemistry of Clouds and Weather Modification Research is to provide guidance to Members on the rationale underlying all aspects of weather modification and on the promotion of research of the physics and chemistry of clouds and of their applications to all fields of atmospheric sciences.

Research focuses upon the physics and chemistry of clouds with reference to weather prediction, weather modification and atmospheric composition and pollution.

Research into the role of clouds in chemical transportation of pollutants, as well as their precipitation processes is also featured in the programme.

Between 1979-1981 field studies of a WMO-managed Precipitation Enhancement Project (PEP) were conducted, which contributed significantly to the development of an international consensus on precipitation enhancement.

The 34 reports published regarding PEP are sought-after references for the scientific basis upon which activities and decisions concerning weather modification are based today.

WMO also organizes and conducts at approximately four-year intervals Scientific Conferences on Weather Modification that are recognized as significant dates in the international calendar of weather modification events.

The Programme is also active in promoting research on the better understanding of cloud processes and their representation in numerical models.

Several cloud modelling workshops have been organized in collaboration with the scientific community.

Recently, a major scientific workshop on new cloud seeding techniques using hygroscopic flares was held in Mazlatan, Mexico.

This new technique already provided very encouraging results for precipitation enhancement in South Africa, Thailand and Mexico.

The promotion of research on physics and chemistry of clouds is the focal point of activities in the programme.

Current activities also center around guiding Member countries on all aspects of weather modification.

In addition, WMO compiles information from Members on their activities and publishes an annual Register of National Weather Modification Projects, the only publication of its kind containing such information.
