ART has also funded the development of a new statistical analysis methodology that enables the results of trials, or commercial applications, to be evaluated in an effective time frame, something that has eluded and disadvantaged the application of cloud seeding in Australia for decades. Explain why Argentina has great potential for economic growth. A rain shadow effect is the term used to describe the situation whereby a dry, often desert-like, side of a mountain rarely receives wind and rain. The trade winds tend to favour an easterly direction (especially in summer and autumn) over eastern Australia and therefore moist winds are forced to rise up the mountains.
