Wind profiles are fundamental to the research and
applications in boundary layer meteorology, air quality and numerical
weather prediction. Large-scale wind profile data have been previously
documented from network observations in several countries, such as Japan,
the USA, various European countries and Australia, but nationwide wind
profiles observations are poorly understood in China. In this study, the
salient characteristics and performance of wind profiles as observed by the
radar wind profiler network of China are investigated. This network consists
of more than 100 stations instrumented with 1290 MHz Doppler radar designed
primarily for measuring vertically resolved winds at various altitudes but
mainly in the boundary layer. It has good spatial coverage, with much denser
sites in eastern China. The wind profiles observed by this network can
provide the horizontal wind direction, horizontal wind speed and vertical
wind speed for every 120 m interval within the height of 0 to 3 km. The
availability of the radar wind profiler network has been investigated in
terms of effective detection height, data acquisition rate, data confidence and data accuracy. Further comparison analyses with reanalysis data indicate
that the observation data at 89 stations are recommended and 17 stations
are not recommended. The boundary layer wind profiles from China can provide
useful input to numerical weather prediction systems at regional scales.
