In a previous post, we talked about the city of Wichita Falls and how bad the drought has gotten in this part of Texas. They are so desperate for rain that they took a vote last week on using cloud seeding to help make it rain. This process involves spraying silver iodine and dry ice from an airplane into clouds. The particles then bond with moisture in the cloud, creating bigger, heavier rain drops. Thus more rain reaches the ground. They voted yes to try cloud seeding.
Since the 90s, there have been other communities in Texas who have used cloud seeding to help with drought conditions. Results showed a 10-20 percent increase in rainfall, which sounds good, but it really isn’t. To prove that extra amount came from cloud seeding alone would be hard to show, and other meteorological factors would have to come into play.
The only way to drastically improve a drought is to go through a flood. You need the overall weather pattern to become favorable for rain, whether from a tropical system or a slow, moving storm system that dumps a lot of rain over time. Quick moving, storm events will not cut it because it will not fill up lakes or rivers. By Spring, if the dry line sets up east of Wichita Falls, there will never be a decent chance for cloud seeding to work.
I understand that drastic times call for drastic measures. However, I feel cloud seeding will not work to lift the drought in northwest Texas, or in any other part of the state. The weather works in cycles. We go through dry periods, wet periods, and everything in between. Sometimes you just have to try and survive and keep praying for rain.
