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 main idea of both the passage and the lecture is about the effects of cloud seeding to prevent damaging the seed land with hail. In this line of thought, the reading states that using cloud seeding is useful and cites some reasons which cloud seeding is employed and reaching the good results. The lecturer, on the other hand, casts doubt on all of the three episodes of arguments mentioned in the passage, believing that none of these strategies are practical and lead to the real world. In the rest of the passage, a comparison between them is provided.
First of all, the reading and the listening materials talk about laboratory experiment which efficiently of the cloud seeding has been check. The author explains that 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. Thus, the author contends that Experiments in the laboratory support the idea that cloud seeding is effective. On the contrary, the lecturer believes that laboratory experiment is different from real conditions. Although, laboratory experiment may prevent hail to damage seed or agricultural lands in the real case may prevent any preoccupations and not only seeds but also lands may damage. This directly contradicts what the passage indicates.
Second, both the text and the talk discuss evidence of the Asia cloud seeding employment. The author points out that in some Asian countries, for example, cloud seeding has been successfully used to control precipitation in urban areas. Therefore, the author elaborates that these positive results suggest that cloud seeding should also be effective in protecting fields and farms in the United States. However, the lecture notes that the cloud seeding procedure is done in the urban area in Asia which has a good condition for cloud seeding because air is polluted; while, the cloud seeding procedure will be done in the unpolluted area in the United State. This was another place where experience contradicted the theory.
Eventually, local studies in the United State farmlands which are discussed by both the passage and the lecture. The author mentions that 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. Hence, the author suggests that the study found that in an area where cloud seeding was used there was reduced hail damage compared to previous years. The lecturer rebuts this argument. The lecturer states that local experience is done in the special area of the United State, so it isn’t very reliable. The professor thinks that this experiment should be done in the whole of the universe and then the reliability of the cloud seeding could be check. This opinion directly contradicts the passage presented and making it infeasible.
Sum up, although the passage provides some reasons to the usefulness of the cloud seeding in dealing with the hail, the lecture opposes about the effectiveness and possibility of those reasons.
