Abstract : This report provides northern hemisphere maps of monthly 90-, 95-, and 99-percentile scalar speeds (10-, 5-, and 1-percent extremes) for altitudes 30 through 60 km. Observed meridional and zonal mean winds and their associated standard deviations were used to derive the magnitude of the mean monthly wind vectors and vector standard deviations. Extreme scalar speeds were then calculated from the magnitudes of the vector means and vector standard deviations, assuming a circular normal distribution. The data used to derive these values consist of wind measurements at and above 30 km from 8 years of data at 12 Meteorological Rocket Network (MRN) stations in the northern hemisphere. Also presented are tables of monthly and annual 10-, 5-, and 1-percent wind-speed extremes at each of the 12 MRN stations. (Author)
