![]() For example, a 5 m/sec wind converts to a 11.19 mph wind, and a 10 m/sec wind converts to 22.37 mph. To convert meters per second into miles per hour, multiply by 2.237. Note: Wind speeds shown in the plots are in meters per second. All hours of the day (24 readings per day) are used to construct the wind roses. The legend at the bottom of the wind rose gives additional information such as the unit (m/sec), the average wind speed for the month over all hours, the percentage of time that the winds are calm, and the years, months, and hours of data on which each rose was constructed. All wind roses shown in the dataset use 16 cardinal directions: north (N), north-northeast (NNE), northeast (NE), etc. The wind roses in this dataset contain additional information, in that each spoke is broken down into discrete frequency categories that show the percentage of time that winds blow from a particular direction and at certain speed ranges. The wind roses are based on hourly data from NOAA's Solar and Meteorological Surface Observation Network (SAMSON) dataset. The images are organized by state, by city within each state, and then by month. ![]() The National Water and Climate Center provides a dataset of wind rose plot images in. ![]() Each concentric circle represents a different frequency, emanating from zero at the center to increasing frequencies at the outer circles. The length of each "spoke" around the circle is related to the frequency of time that the wind blows from a particular direction. Presented in a circular format, the wind rose shows the frequency of winds blowing from particular directions. A wind rose gives a succinct view of how wind speed and direction are typically distributed at a particular location. ![]()
