Why is understanding local weather conditions vital for aerial application?

Understanding local weather conditions is essential for aerial application primarily because weather influences drift, evaporation, and the effectiveness of chemicals used in the process. Weather factors like wind speed and direction play a significant role in the potential for chemical drift, which is when applied substances move away from the target area, potentially affecting nearby crops, water sources, or even human populations.

Additionally, temperature and humidity can impact the rate of evaporation of the chemicals, determining how long they remain effective once released into the atmosphere. High temperatures and low humidity can lead to quicker evaporation, rendering the application less effective and possibly requiring reapplication to achieve the desired results.

By having a solid understanding of these weather influences, an aerial applicator can make informed decisions that maximize the efficacy of their applications while minimizing potential negative impacts on surrounding areas.
