Distribution and Features of Low-level Jets in China during the Warm Seasons Using WRF Model

摘要

The detailed distribution and features of Low-level jets (LLJs) in China are documented using hourly output from 9-km horizontal resolution Weather Research and Forecasting mesoscalemodel (WRF) for warm season (May,June and July) from 2006 to 2011.The Low-level jets are classified into two types based on height:Boundary Layer Jets (BLJs,about below 1 km) and synoptic-system-related LLJs (SLLJs,within 1-4 km).We found that there are four rich LLJ regions in China:TarimBasin,Southeast China,North China and Tibetan Plateau.
