Brisbane Microclimate Science Fair Projects

Objectives/Goals

The objective of this project is to determine if microclimates occur in the city of Brisbane and if the topography of the mountain causes these microclimates to occur. Brisbane is confined on the northeastern slope of San Bruno Mountain with a geographic boundary of about 2 miles.

Methods/Materials

I selected six sites in which to collect my data, which were divided into two grids. The sites represent a variety of altitudes and locations in proximity to the mountain and the nearby San Francisco Bay. These sites are within a radius zone of about 1-2 miles. I conducted my experiment by measuring barometric pressure, wind speed, and temperature for fifteen days at 8:00am and at 3:00pm each day. The data was added and averages were calculated for each site in each category.

Results

Microclimates do exist in Brisbane. Sometimes the temperature would vary from 2-10 degrees between sites and the wind speed would vary from 0-20 mph between sites. The location closest to the mountain was shielded by the wind but cast in its shadow, and the locations further away were windier but had warmer temperatuures The results of the warmest, coldest, windiest and calmest location varied slightly from my prediction.

Conclusions/Discussion

My conclusion is that the topography of the mountain creates microclimates within the city of Brisbane. I learned that our town is located on an amazing mountain with a variety of climates in a very small geographic area. original abstract: http://www.usc.edu/CSSF/History/2004/Projects/J0604.pdf
