High-speed streams (HSSs) in the solar wind are an important physical driver of space weather and even of space climate considering long periods of time. Thus, the need for a HSSs database for extended time-series is extremely motivated. HSSs catalogues (Lindblad and Lundstedt, 1981, 1983; Lindblad, Lundstedt, and Larsson, 1989 and Mavromichalaki, Vassilaki, and Marmatsouri, 1988; Mavromichalaki and Vassilaki, 1998, Gupta and Badruddin, 2010, Maris and Maris, 2012) cover solar cycles 20 to 23. Our complex catalogue lists HSSs produced by coronal holes and their effects in the terrestrial magnetosphere - the so-called geomagnetic storms - for Solar Cycle 24 (2009 to 2019). The catalogue is structured in three parts describing the high-speed stream characteristics, the interplanetary magnetic field state, and the properties of the associated geomagnetic storms. The catalogue is available online at http://www.geodin.ro/varsiti/.
We will also present an empirical model to estimate the probability whether or not a HSS produced by a coronal hole will be associated with a geomagnetic storm. The model is applied to the HSS data from our catalogue and may correctly predict HSS - geomagnetic storm association with an acceptable efficiency.
