Hail—pieces of ice that form and fall from clouds instead of snow or rain—has always been a problem for farmers in some areas of the United States. Hail pellets can fall with great force and destroy crops in the field. Over the last few decades, a method of reducing hail, called "cloud seeding," has been tried. In cloud seeding, the chemical silver iodide is sprayed on storm clouds from an airplane. This makes the clouds produce harmless rain or snow instead of hail. Several pieces of evidence suggest that cloud seeding has been effective in protecting crops from hail.
Laboratory experiments
Experiments in the laboratory support the idea that cloud seeding is effective. Hail usually forms water vapor that is close to the freezing point However, when experimenters added silver iodide to cold water vapor in the laboratory, they often observed light snow forming instead of hail pellets.
Evidence from Asia
There is evidence about the effectiveness of cloud seeding from several countries around the world. In some Asian countries, for example, cloud seeding has been successfully used to control precipitation in urban areas. These positive results suggest that cloud seeding should also be effective in protecting fields and farms in the United States.
Local studies
A few local studies also support the value of cloud seeding. One study conducted in a farming region in the central United States, for example, directly monitored crop damage due to hail. The study found that in an area where cloud seeding was used there was reduced hail damage compared to previous years.
The reading passage and the lecture both discuss the effect of 'cloud seeding' in reducing the harmful effect of hail. In the reading part, the author mentions that there are several fact that shows cloud seeding would be impact in this issue. In the listening part, however, the speaker challenges what the author ststes and rebuts the reasons.
To begin with, as mentioned in the article, the author suggest that based on the laboratory experiments, it means that adding silver to cold water, can be effective; nevertheless, in the listening part, the speaker rebuts the reasons asserting that silver can actually effect on the quantity of the rain, resulting in lack of water and indeed cause drought. it has negative effect on raising crops.
Secondly, the author sets forth that evidences from asian countries indicate that they can use to control the damages in urban arias. Nonetheless, the lecturer flatly contradicts the the reasons and contends that it might not repeated in the us; urban regions are highly polluted and in the asian countries they have used it on urban aria not in its rural. In hence, it cannot be effective on unpolluted regions such as the place of farm lands.
Finally, the author claims that local studies improved the fact that the places, which in clouds seeding was there, the damages was less that others places. In contrasts, the professor is off the opinion that the results of the reduction in hail were because of the natural variation weathers on that region; it was not just the reason of the cloud seeding.
