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 is about the effectiveness of cloud seeding. It provides three supporting ideas in order to bolster its position. However, the professor says, the idea is not clearly depicts any feasibility. She refutes each of the passage claim.
First, the article states that in laboratory examination it was observed light snow instead of hail pellets because of the silver iodide treatment. But, the narrator denies this idea. She says, although it was possible to create an environment where the action of silver iodide was proven but in real life the feasibility is questionable because the there is a chance of drought where lack of water can causes the more harm for the crop.
Second, the reading asserts that the proof from Asia was also applicable for the United States. Apart from that, the lecturer refutes this claim. She describes, the feasibility of one thing in Asia may not same for the United States. Moreover, she says, in Asia the urban and polluted environments posed benefits for cloud seeding but that did not ensure the same benefits for the unpolluted areas in the United States.
Third, the written excerpt claims that the regional hail driven damaged provoked the cloud seeding method. The point is quite unconvincing with the narrator. The professor elaborates that the reduction of hail cut the chances of crops in east, north and south. In addition, it downgrade the urge to implement the cloud seeding method.
