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 mentons 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 athour sets forth that labratory experiences indecate that by adding silver iodide to the cloulds, we can control hail and produce harmless rains or snows; nevertheless, in the listening part the lecturer refutes the reasons asserting that the reasons just mentioend are not clear enough, for example adding silver have any prosipitations such as in the reigon that there is no rain enough, it causes drough and lack of water for growing crops.

Secondly, the author points out that in the Asian countries, this method workes well and control hail in urban cities. Nonetheless, the professor flatly contradicts the reason and contends that it migh have work in urban earies that has varies pollution in the air, but in the rural eiria whish is emthy of pollution may not work and cannot reapet in us, becouse of the favorable sitiation for cloud seeding is in the urban riegon.

Finally, the author claims that few studies in local airia in us indicate that clould seeding causes reduce the hail damages. In contrast, the professor is of the opinion that studies illustrated that it workes not becouse of the cloud seeding, while, the reasons was natural weather which reduces the hail.
