Catalogue of geomagnetic storms of CIR/HSSWS origin with limited atmospheric influences
The catalogue of over two hundred geomagnetic storms initiated by Co-rotating Interaction Region (CIR)/High-Speed solar wind Stream (HSSWS) in the period of 2016-2023 is filtered to include only intervals with no sudden stratospheric warmings or only insignificant tropospheric activity over European region.
The identification of the CIR/HSSWS intervals is based on solar wind stuctures catalogue: https://doi.org/10.1051/swsc/2012003
The start and ending times are provided as year/day of year(DOY)/hour, but due to typically gradual decrease of CIR/HSSWS intensity the ending times are only estimates considering more parameters than only the solar wind speed. Events with possibly remaining previous ICME influence were removed as well as insignificant intervals which overall reached maximal Kp 2 and less.
Indication of possibly significant influence by tropospheric convection in Central Europe with some probability of excitation of gravity waves (GWs) was performed by evaluating multiple meteorological disturbing factors (jet stream occurrence, tropospheric convection producing gravity waves including thunderstorm activity at surface, 850 hPa and 500 hPa levels).
All sudden stratospheric warming events were removed including minor as well as final warming events.
The catalogue allows analysis of geomagnetic storms effects on ionosphere or directly on technological systems which were clearly caused by CIR/HSSWS and not by sudden stratospheric warmings or various significant tropospheric events like convection associated with frontal passages.
