A Plan for the next phase in Weather Modification Science and Technology Development (PDF)
Technological and scientific advances have recently yielded new seeding material,polarimetric radar, Doppler radar and software, and enhanced computational resources. Hence, an impetus for developing systems that monitor and manage atmospheric events.
[As such,] atmospheric events are treatable using proven and some new modern weather modification technologies, and they include hurricanes, tornadoes, and pollutant transport.
Consequently, the next phase in weather modification science and technology development is to outline a high level national program plan for developing modern weather modification science and technologies, that takes advantage of lessons learned, recent science and technological advances for more effectively benefiting society.
There is a need to develop the ability to better simulate, and thereby, identify and monitor atmospheric events, airborne pollutants, and select inadvertent weather modification signatures.
This ability combined with improved seeding
technologies will maximize the benefit and success of this program since they contribute to the resolution of water-related issues (especially water scarcity).
combined with improved scientific understanding, provide a more useful tool for determining when and where the atmosphere or cloud can most likely benefit from implementing the improved or new technologies.
Developing improved dispersion techniques and higher yield cloud seeding agents are needed for obvious reasons. The development of technologies to ‘treat’ hazardous weather systems (e.g. freezing rain, hail formation, tornadoes, hurricanes) are more critically needed, and will benefit from past and ongoing research results, especially research using ground-, air-, and
satellite-based remote sensing devices (radars including Doppler, lidars,
radiometers, and others).
The aforementioned need is rather ominous, but necessary and attainable in time.
Initial efforts to develop an understanding of how present-day cloud seeding technologies can be applied and modified to lessen the socioeconomic impacts of hazardous weather events and materials might begin with the information gained from simulating these systems, then with these models modify them to include the results from applying various seeding technologies.
The modeling of seeding agent tracer study results would greatly improve seeding agent placement within cloud systems, and they could form the basis for Homeland Security needs.
The existing cloud seeding technologies are operationally used to reduce hailstone size, and may possibly be used to reduce the intensity of rotational hurricane winds.
The reductions in hurricane rotational wind speeds following cloud seeding (“Esther” in 1961, “Beulah” in 1963, and 30% for“Debbie” in 1969), were not statistically distinguishable from the range of natural
variability, and is not yet scientifically accepted.
Consequently, modeling studies should dominate these efforts, initially.
Inadvertant modification studies need to be increased, and not solely from a climate change point-of-view.
For example, a land cover change from agricultural to urban over a modest area can introduce a climatic forcing similar in magnitude and direction to that from carbon dioxide
Here initial efforts should at least focus on strategies for (a) minimizing the effect from inadvertent modifications to the atmosphere, and (b) neutralizing airborne pollutants within cloud systems or redirecting their air trajectories to settle on ‘safe surfaces’.
