Which direction provides the second highest percent of the total wind in Fresno? In general, which direction does the wind typically come from in Fresno? How can you tell?Ībout what percent of the wind in Fresno, California comes from the northwestĪbout what percent of Fresnoâ€™s wind comes from the northwest at 5.4 â€“ 8.49 mps? Use Diagram B, a wind rose illustrating the direction and velocity (speed) of wind in Fresno, California, to answer the questions below.

About what percent of the wind in Middlefield comes from the north at speeds of 2 - 5 mps?Ībout what percent of the wind in Middlefield comes from the north at speeds of 5 -10 mps? The percent of wind in Middlefield that comes from the north at 10 mps or greater, is neither 18% nor 20%, but about 2%. It illustrates that about 20% of the time, the wind in Middlefield comes from the north.Ībout what percent of the wind in Middlefield comes from the north at 0 - 2 mps? This particular wind rose sector indicates wind (measured in meters per second, or mps) coming from the north. Use Diagram A, a wind rose for the imaginary town of Middlefield, USA to answer the questions below. The high speed winds are shown further from the center. Percentages for the lower speeds are shown closer to the center of the diagram. Each portion of the sector is shaded or colored to indict a particular range of speeds. The individual sectors are also divided to show wind speed as well as direction.

Similarly, a sector to the right indicates that wind is coming from the east and blowing to the west.Ī sector that is enlarged (or lengthened) means that the wind comes from that direction more often a short (or squashed) sector means the wind does not come from that direction very often. In this case, the wind rose illustrates that the wind from the north blowing to south. Like a compass rose, the top sector (or wedge) on a wind rose represents north. Imagine a circle cut into eight sectors or wedges. When determining the position of a new building on a site, they want to situate the building in such a way that will maximize the direction and velocity (speed) of the wind, allowing for the best natural cooling breezes. The data contained in a wind rose helps architects and engineers understand the existing conditions at a particular site. Meteorologists, architects, and engineers often use a diagram called a wind rose to visualize the frequency of wind direction at a particular location. How can a school be positioned on its site to take advantage of wind and the best views?
