Wind Rose Plots

What are Wind Rose Plots?

Wind Rose plots are graphical representations of wind observations and calculations such as speed and direction.  They are used to analyze wind patterns over periods of time like a day, a month, or even an entire year.  For this particular lab, we used free software from the Lakes Environmental website and we used data from the EPA website to make the wind rose plot.


What do they look like?

Below I have provided 3 pictures of wind rose plots that I created with the Lake Environmental software.  I used data from my birthday, June 12, 1992 for the blowing-from and blowing-to plots, and the month of June during 1992 for an average month.  Since my hometown is about 40 minutes away from Tallahassee, Florida, I used data collected from the wind station at the Tallahassee Regional Airport. 













Blowing From- June 12, 1992

Blowing To- June 12, 1992

Monthly Average- June 1992

Map Lab

Choropleth Map

A choropleth map uses different gradients of color that corresponds to a certain quantity or average to represent specific areas on a map.  These maps are most commonly used to display population density in certain areas.  The map on the right displays the population in the counties of Georgia in 2000.




Dot Density Map

A dot density map is also another kind of thematic map used to show population.  On a dot density map, each dot represents a specific number.  The map on the right displays the Hispanic population in the United States.  The areas with the most dots have the largest Hispanic populations.







Proportional Symbol Map

On a proportional symbol map, the area of the symbol (normally circles like below) corresponds to whatever is being measured. The map on the right displays the total murders per state in 2009.  The states with the larger dots have a higher total of murders than those with smaller dot.  The legend in the lower right corner denotes the number of murders for each dot size.





Isopleth Map

An isopleth map uses contour lines to display variation in value such as, elevation, depth, and inches of rainfall.  There are several different types of isopleth maps.  A bathymetric map displays the variation in depth of bodies of water, and a topographic also uses contour lines to show variation in elevation.  The map on the right is a bathymetric map of the Gulf of Mexico.  The lightest areas on the map represent the most shallow parts of the Gulf, while the darkest areas indicate the deepest points.

About Me

Justice. Speaking for the voiceless, and avenging the powerless. These are not only missions of Captain America, but are also the duties that Haley Hubbard wants to fulfill someday. Her talkative nature on the subjects of traveling and the law contrasts her silent-type personality. However, Hubbard once owned the mock trial courtroom and knows she will own an actual courtroom once again after law school. Hubbard is a 21-year-old senior, double majoring Political Science and Spanish at Mercer University. Hubbard could see herself as a legal/crime analyst or a political pundit on news or television after law school.
