Cloud seeding is a weather modification technique which involves the introduction of a seeding agent into suitable clouds to encourage the formation and growth of ice crystals or raindrops, in turn enhancing the amount of precipitation falling from the cloud. Cloud Seeding Economic Impacts By Aaron Gilstad In previous articles on cloud seeding, I described the inner workings of cloud development, how cloud seeding operations are done, and the reasoning behind targeting as it is done on the North Dakota Cloud Modification Project (NDCMP). In this final article of the series, I will attempt to shed.

If anything, cloud seeding in one place leads to more precipitation downwind, not less, said Darin Langerud, who oversees cloud seeding for the North Dakota Atmospheric Resource Board. Cloud seeding is a type of weather modification that aims to change the amount or type of precipitation that falls from clouds by dispersing substances into the air that serve as cloud condensation or ice nuclei, which alter the microphysical processes within the usual intent is to increase precipitation (rain or snow), but hail and fog suppression are also widely practised in.

The North Dakota Cloud Modification Project (NDCMP) is an operational program that seeds clouds for hail damage reduction and rain enhancement in western North Dakota. Counties currently participating in the program are Bowman, McKenzie, Mountrail, Ward, Williams, and part of Slope.
BISMARCK – Cloud seeding concluded for the District II operations area of the North Dakota Cloud Modification Project on Sept. For the season, there were flight hours flown in the.

Operational cloud seeding has been conducted over parts of western North Dakota since the ’s. Operations began with ground based seeding in the early years, but by the early ’s airborne delivery of seeding agents became the preferred by: 1.
But some North Dakota growers are trying to end a state cloud-seeding program that’s been around for generations, believing it may be making the drought worse. Besides anecdotal accounts from decades of farming, they cite satellite images of clouds dissipating after being seeded and statistics over two decades that they say show less rainfall.

The NDCMP has two objectives for their cloud seeding. The evaluation of the 11 operational cloud seeding programs has led to the following important findings: 1) Operational cloud seeding succeeded in increasing the streamflow in 6 of the 11 major watersheds in the Sierra Nevada Mountains.
There was a statistically significant seeding effect in at least one sub-basin in each of the 6 by: 7. In terms of a statistical test, detailed studies should be conducted on various processes, including design and implementation of cloud seeding experiments and operations, determination of the target area and the control area, judgment of the effect duration, establishment of the evaluation indicators, selection of the covariates, and Cited by: 1.
Cloud seeding, which involves spreading aerosols (silver iodide or sodium chloride) into the upper part of clouds to stimulate the precipitation process to form rains, was last taken up in the Author: DH News Service.

Moen * North Dakota State Water Commission, Bismarck, ND Darin W. Langerud North Dakota Atmospheric Resource Board, Bismarck, ND 1. INTRODUCTION An important aspect of cloud seeding operations is the accurate documentation of seeding activities.
A National Academies panel in determined there was "no convincing scientific proof" that cloud seeding worked, and it called for more rigorous evaluation of cloud seeding's merits.
Today California, Idaho, Nevada, Utah and Wyoming have winter cloud seeding programs, and Texas and North Dakota have summer programs, which aim to increase rain and decrease hail. Cloud seeding machines are nothing like the “snow guns” used to. His primary focus is on the research and operations of cloud seeding in southern Idaho.
He was heavily involved in the success of the SNOWIE (Seeded and Natural Orographic Wintertime Clouds: the Idaho Experiment) research project. Derek has worked on cloud seeding projects in North Dakota, Wyoming, India, Alberta, and Idaho.A major program of the Board was the North Dakota Cloud Modification Project (NDCMP) covering an area of 10, square miles in western North Dakota, including Bowman, McKenzie, Mountrail, Ward, Williams, and part of Slope counties.
Designated aircraft, airports, and staff carried out the goals of NDCMP. County funds came from a mill levy. While there are certainly exciting and important aspects related to the future of winter orographic cloud seeding, challenges remain.
The panelists provided a wide range of issues that still need to be addressed and/or that present challenges to the evaluation of cloud seeding, from measurement and modeling limitations to logistical and public relations by: 4.
