Abstract: Using the wind profiler data and the monthly and annual observation information at Harbin Taiping International Airport from 2019 to 2021, the characteristics of low-level jets were statistically analyzed from the aspects of monthly changes, diurnal changes, wind direction, duration, center speed, center height, and the relationship with precipitation.The results show that the low-level jets at Harbin Airport have obvious seasonal variation characteristics, and the probability of occurrence in spring and autumn is significantly higher than that in summer and winter.Low level jets can occur at any time of the day.The daily change of the occurrence time is characterized by the largest number of occurrences from early morning till noon, gradually decreasing from noon, reaching the lowest level at midnight, and increasing again from then on.For the wind direction, the low level jets are dominated by southwest jets.From the perspective of the jet duration, the highest number of days are accompanied with the jet duration of 7~12 h, followed by the jet duration longer than 18 h, and the lowest number of days are associated with the jet duration of 4~6 h.The center height of the low level jets mainly ranges from 0~500 m and the center wind speed hovers around 20 m/s.Precipitation is closely related to low level jets.Moreover, it is linked with the inversion layer.Significant correlation is identified between the maximum center speed of the low level jets and the maximum precipitation in a single day.The strengthening of the center speed of the low level jets may lead to the enhanced maximum precipitation in a single day.
