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 in 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 lecture have a conflicting opinions about whether or not the cloud seeding is an sufficient approach to preserve the crops from hail. The article strongly postulates that many data and experiments from researching in areas propose that adding silver iodide to the clouds has been effective in protecting crops from hail. On the other hand, the listening adamantly delinates that it has been clear that the cloud seeding can't benefit crops by protecting it from hail.
First and foremost, according to the author of the excerpt, in laboratory experiment snow was created instead of hail. Furthermore, adding silver iodide to water vapor that is close to the freezing point resulted in forming snow. Nonetheless, the lecture offsets these points by declaring that it maybe right in the laboratory experiment the snow will be formed. However, in real life it could be snow, rain, or hail. Also, using cloud seeding in areas where there are no much water in the cloulds will result in drought. As a result, lack of water in that area.
The speaker in the lecture further points out that the could seeding was used in urban areas. which have hight air pollution. In other words, pollution can result in favorable coditions. As a result, the cloud seeding can't be used in farming region in usa. These claims refute the writer implications of how cloud seeding method is an effective method to be used in several countries despite considering pollutin factor.
The article lastly asserts that the cloud seeding was used in a couple of local areas. one was used in farming region. Subsequently, the crops damage were reduced despite the other areas around. The speaker in the lecture counters these points by insisting that this experiment is not convincing because of the decline in the natural weather in that year.
