WMO

Background from CAS-16

More than 42 countries have active weather modification projects to enhance rainfall, to suppress hail, and to disperse fog and haze.

The updated document of the “WMO Statement on Weather Modification” prepared by the Expert Team on Weather Modification (ETWM) in 2010.

The lack of contributions to the Weather Modification Research Trust Fund from Members. This holds a considerable risk to future activities, including the quadrennial organization of the International Conference on Weather Modification Research and the review of the scientific status and guidance material on weather modification.

WMO

Background from CAS-16

The activity on weather modification be considered to continue for another two years with limited financial support from the trust fund, followed by a final review on its future

Encouraged Members with an interest in this activity to contribute to the Trust Fund for Weather Modification to sustain and continue the activities in advancing the practice of sound science in weather modification.

WMO

The way forward

Suggest a (final) meeting of the ET on Weather Modification in 2015 to review the statement on weather modification

At 17th session of WMO Congress in 2015:

Give clear indication that the quadrennial WMO Scientific Conference of Weather Modification will not be continued (last one in 2011)

Request a decision that the work of the ET on Weather

Modification be concluded.
