Evaluating Winter Orographic Cloud Seeding: Design of the Wyoming Weather Modification Pilot Project (WWMPP)

Design and Preliminary Results of the Wyoming Weather Modification Pilot Program Randomized Seeding Experiment

The Wyoming Weather Modification Pilot Program (WWMPP) is funded by the State of Wyoming through the Wyoming Water Development Commission (WWDC), and is unique among statesponsored programs in the USA in that it includes a substantial evaluation component. The main purposes of the WWMPP are to establish an orographic cloud seeding program in three target areas (the Medicine Bow Range, Sierra Ma...

A Numerical Model to Investigate Optimum Liquid Carbon Dioxide Seeding Rate in Weather Modification Projects

Sulfur dioxide oxidation in winter orographic clouds

The production of sulfate in cloud droplets, and the attendant depletion of sulfur dioxide (SO2) oxidants were studied in wintertime orographic louds over southeastern Wyoming. By periodic (5-20 min) releases of SO 2 into the cloud the mixing ratio of SO 2 was raised to about double its background value of 0.7 parts per billion by volume (ppbv). Average values of the in-cloud reaction time, pse...

Evaluating the Effectiveness of the Courseware Development Project: Pilot studies

This project involves a comprehensive generalizable and transferable evaluation of the Courseware Development Project (CDP) at Dalhousie University's School of Business Administration. This C$3 million, three-year project is divided into four levels over three time phases. The results of the study of the impact of this unique project are expected to be both relevant and applicable to other univ...

Evaluating the Seeding Genetic Algorithm

In this paper, we present experimental results supporting early work on the Seeding Genetic Algorithm. We evaluate the algorithm’s performance with various parameterisations, making comparisons to the Canonical Genetic Algorithm, and use these as guidelines as we establish reasonable parameters for the seeding algorithm. We discuss how experimental results complement and confirm aspects of the ...
