Quick Answer. According to a Texas A&M University website, the Mexican flag stands for Mexican values and historical tradition. The three colors of the flag were the colors of the Army of the Three Guarantees, which fought for independence from Spain.
This image explaining cloud seeding shows the chemical either silver iodide or dry ice being dumped onto the cloud, which then becomes a rain shower. The process shown in the upper-right is what is happening in the cloud and the process of condensation to the introduced chemicals.loud seeding has been shown to be effective in altering cloud structure and size and in converting supercooled liquid water to ice particles. The amount of precipitation due to seeding is difficult to quantify. A key challenge is in discerning how much precipitation would have occurred had clouds not been seeded.
But how do they work? And can you really claim that cloud seeding caused a particular storm? We asked cloud-seeding expert Arlen Huggins, associate research scientist in the division of atmospheric sciences at the Desert Research Institute in Reno, Nev., to give us some answers. [An edited transcript of the interview follows.] Tell us a little about the basics of cloud seeding. Clouds, whether in summer or winter, are not perfectly efficient at producing precipitation. There's some part of a storm that's much less than 100 percent efficient in turning clouds into precipitation.
