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 protect
The reading and the lecture are both about cloud seeding which is a method for reducing problems from Hail. The author of reading believes that this method can be effective to prevent damage made by hail pellets. However, the lecturer casts doubt on the claims made in the article. She think that the effectiveness of this method is unclear.
First of all, the reading posits that laboratory experiments shows that cloud seeding is a useful way to change hail to light snow. Nevertheless, this point is challenged by the professor. She mentions this may be happen under laboratory condition but in real world this could be prevent producing of snow and rain. Furthermore, the professor states that this could be led to drought and as a result of this method water shortage can cause more damage to crops.
Second, the author claims that cloud seeding method used in several countries and the result was positive. It is argued that in some Asian countries cloud seeding has been applied to control precipitation in urban regions. This argument is rebutted by the lecturer. She claims in urban areas air pollotin is responsable for positive result of using this method. She states that cars and industries in urban area are the reason for air pollotion but in rural and farmland the air is clear and without air pollotion this is not possible to have same result as urban regions.
Finally, the author mentions that local studies also suggest that cloud seeding is valuble method. The author gives an example of a study which conducted in farming region in the central United stated and the study support the efectivness of cloud seeding method. The lecturer, on the other hand, refuses this claim bay saying that the local studies result is not convincing. She says that decrese in the damage from hail is not becuase of cloud seeding method. She puts forth the idea that reduction of hail is because of natural variation of climate which also happened in other regions.
In sum, all three reasons mentioned in the reading are effectivelly challenged by the lecturer.
