The Qinghai-Tibet Plateau is the source of many major rivers in Asia, providing essential water for hundreds of millions of people, and is known as the "Water Tower of Asia". The main source of water recharge for the Asian Water Tower is precipitation from the Tibetan Plateau, of which the Tibetan Plateau vortex (TPV) is one of the important precipitation-producing systems on the Tibetan Plateau. Due to the complex topography of the Tibetan Plateau and the lack of observational data, there are still many gaps in the understanding of the climatic and structural characteristics of the TPVs and their formation and change mechanisms. This dataset uses multiple sets of reanalysis data and objective identification methods to obtain a long time series TPVs dataset, including the location, radius, intensity, life history, and movement path and other characteristics. The reanalysis datasets used in the dataset are: NCEP1 (NCEP/NCAR), NCEP2 (NCEP/DOE), ERA-Interim, ERA-40, ERA-5, CFSR, MERRA2, JRA55, NCEP FNL, CRA40, etc. NCEP1 and NCEP2 have lower resolution and the obtained highland low vortices are not applicable as climate feature analysis.

File naming and required software

File naming: The TPVs dataset is stored in text format, and the file name is "reanalysis data-yyyy.txt", where yyyy is the year, e.g. ERA5-2010.txt means that the file describes the TPVs obtained from the ERA5 reanalysis data for the year 2010.
The first row shows the number of TPVs for that year, and the second row gives the TPV properties for each column.
After that, the first line of each TPV gives the name and the number of atcive times. A TPV is named as: TPV_YYYYMMDDHH_LON_LAT, YYYY, MM, DD, and HH are the year, month, and day when the TPV was generated, and LON and LAT are the initial locations of the TPV.
The location and properties of the TPV for each time step are given line by line.
