| Abstract: | From the architectural point of view, the vertical distribution of strong gusts over large cities is very important. Although special instrumentation for very strong winds is required, the available recording devices are generally not adequate. Only rather recently have telemetric techniques advanced sufficiently to ensure a practical system for measuring very strong gusts. Records from fast-response anemometers for each minute (sixty measurements per hour) may clarify the physical processes in the atmospheric boundary layer in the lowest 250-m layer over the city of Tokyo. The new system can be considered practical since it was operated from May 1968 to July 1969 under a variety of climatic conditions, especially under strong gusty conditions. |
