英文摘要 | The mountains of Nanyue, Huangshan, and Jiuxianshan in eastern China all have elevations >1200m and the weather stations on the tops of these mountains directly observe atmospheric conditions in the lower troposphere. This study showed that the low-level jets derived from a reanalysis dataset (JRA25) were highly consistent with the winds measured at the mountaintop stations in May and June in the time period 2005-2010. The mountain observations were both continuous and hourly, which compensated for the limitations of the reanalysis and sounding datasets in terms of temporal resolution. The zonal and meridional winds and wind speed at Nanyue Mountain were significantly correlated with the downstream rainfall, with the highest correlation several hours before the peak of the region-average long-duration rainfall events (lasting >6 h). These results suggest that the winds observed by mountaintop weather stations could be used in rainfall forecasting and confirm the influence of low-level jets on rainfall downstream. |
