TPO 36- 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.
The reading and lecture are both about cloud seeding. The article states that cloud seeding is an effective method in protecting crops from hail. However, the lecturer casts doubts about the claims made in the article, saying that cloud seeding is not useful.
First of all, the author points out that in conducting laboratory experiment cloud seeding is effective. The article notes that when silver iodide is added to cold water vapor then light snow will form instead of hail. Conversely, the point is challenged by the lecturer. She says that silver iodide combined with cold water vapor has negative effect because it prevent any precipitation in clouds. Furthermore, she argues that when cloud seeding is conducted in areas where there are limited rainfall, thus, there will be risk for drought and crops will die due to lack of water.
Secondly, the author contends that cloud seeding is effective in urban areas in Asian countries. The article establishes that cloud seeding will also have favorable results in farm lands in the United States. On the contrary, the lecturer rebuts this argument. He suggests that cloud seeding only works in an environment where there are air pollution, car traffic and congestion. Moreover, he elaborates on this by mentioning that cloud seeding will not possibly work in farm area in the U.S because it has clean and fresh air, so precipitation will not occur.
Finally, the author states that in a local study in farm region in central United states they monitored crop damage due to hail. The article denotes damaged to the area where hail occurs drastically dropped when the method of cloud seeding was used. The lecturer, on the other hand, posits that the study is not convincing. In addition, the study in hail damage did not just dropped in area where cloud seeding took place. He puts forth the idea that the whole region has decrease hail storm in that year resulted in natural variation in local weather and nothing to do with cloud seeding.
