上海世博园上空边界层风垂直变化观测研究

The wind velocity variations with height are observed over the EXPO Land,Shanghai using the flat arrayacoustic wind profiler from July 17 to September 28,2007.This study shows the westerly domination in nighttime and easterly domination with low velocity variation at daytime by analyzing the diurnal variations of the local circulations,indicating sea-land wind significantly influences on the circulation in low atmospheric boundary layer.The day-to-day variations of wind velocity with height are characterize...
