Mesoscale Wind Variability in the Vicinity of Berlin, Germany.
Abstract
Mesoscale wind variability over a 35 mile (56 km) distance in the vicinity of Berlin, Germany is discussed in this report. Horizontal differences in windspeed (scalar shear) and wind direction (angular differences) are utilized to compute the deviation of the windspeed and direction (wind-shear) from one measurement location to another at the constant pressure levels: Surface, 1000 mb (near surface), 850 mb (1.5 km), 700 mb (3 km), and 500 mb (5.5 km). Results from other wind variability studies that have appeared in the literature have been obtained from special observing networks, which provided either a limited number of total observations, or many observations concentrated over a period of a few days. The close proximity of two upper-air stations provides an opportunity to establish a climatology of horizontal wind variation. Frequency and cumulative frequency distributions of the scalar shear, angular differences, and the vector shear are included, along with the corresponding 50, 90, 95, 97.5, and 99 percent values.
