Changes in wind direction are extremely important in competitive sailing. For my Measurement and Instrumentation class, I set out to quantify these changes in direction, and determine how they were affected by the geography of the area. I found that 79.5% of gusts were short lived when they were close to upwind obstructions such as buildings. Meanwhile, only 62.5% of gusts were short lived ~0.5 mile away on the other side of the river. This result told us that the wind becomes less steady as you approach upwind obstructions, confirming what we had been seeing on the water.
NOTE: This project could be significantly improved by increased control and standardization in the experimental procedure. Factors such as building height, different sensor properties, and proper downwind alignment were not considered. This project was also conducted before I had completed a fluid dynamics course. Much of the theory is based on an experiential understanding of fluid mechanics derived from sailing experience.
