Comparison of horizontal wind observed by wind profiler radars with ERA5 reanalysis data in Anhui, China

The wind profiler radar network at Anhui province in China was completely constructed for improving warning capacity of meteorological disasters in 2019. In order to verify its proper performance, vertical profiles of horizontal winds were compared with ERA5 reanalysis data during the period January to December in 2021. The wind profiler radars behave good capability in measuring the atmospheric wind with high data collection rates (> 80%). Furthermore, data availabilities of WPRs decrease with the increase of altitudes and they are mostly greater than 90% below 3km in day without precipitation, indicating that the annual mean of the effective detection height is about 2-3km with maximum value (4-6km) in summer and minimum value (around 2km) in winter. More importantly, the WPRs shows excellent agreement with the ERA5 zonal (correlation coefficients > 0.89 and standard deviations 0.76 and standard deviations
