Abstract: A special method has been developed for the study of cells that are embedded in convective rain systems. This method consists of a package of computer programs that use pattern recognition techniques on three-dimensional ...

Abstract: Rangno and Hobbs?s (RH) paper is a scattergun attack on the Israeli rain enhancement experiments that has no basis, as shown in this comment. This approach, unfortunately, has served to complicate rather than clear up ...

Abstract: Analyses of trends of the orographic winter precipitation enhancement factor Ro along the coastal mountain ranges of the west coast of the United States show a pattern of decreasing Ro during the last century by as much ...

Abstract: Alpert et al. in a recent paper challenged the quantification of the suppression of orographic precipitation that was shown in two recent papers by Givati and Rosenfeld to occur in Israel. Their main claim was that the ...

Abstract: Enhancement of precipitation by cloud-seeding operations has been reported in many studies around the world in the last several decades. On the other hand, suppression of rain and snow by urban and industrial air pollution ...

Abstract: The rainshafts of about 3000 summer afternoon convective rain cells in the semiarid region of central south Africa were tracked and measured with a volume scanning radar. The area and time integrated rain volume of each ...

Abstract: Experimental and operational cloud seeding in Israel has been conducted since 1961 by aircraft seeding of silver iodide (AgI) at cloud-base level along a line upwind of target areas. The first experiment, Israeli-1 (1961?67), ...

Abstract: Several important factors that govern the total rainfall from continental convective clouds were investigated by tracking thousands of convective cells in Israel and South Africa. The rainfall volume yield (Rvol) of the ...

Abstract: During the period 1961?75, two cloud seeding experiments were carried out in Israel. The first Israeli experiment had a two-target crossover design. The results indicated a positive seeding effect of 15%, significant at ...
