White-light polar jets on rising phase of solar cycle 24

We studied coronal white-light jets in the polar regions of solar corona in 2009-2014. Jets were tracked on data producing by coronographs COR2/STEREO with the 2.5-16 solar radii field of view. We also considered their characteristics on solar cycle progress: jet occurrence rate of jets per year above the northern and southern poles, angular distributions and measured apparent velocities. The jet mean occurrence rate per year is 234 registered events. It is defined that both occurrence rate per year and the mean apparent velocities are increased to solar cycle maximum. This changes were shown to be different for the north and south polar regions and to depend on polar magnetic fields. The mean apparent velocities are increased by 1.7 times for north pole (from 134 +/- 66 km/s to 229 +/- 59 km/s) and by 2.4 times for south pole (from 101 +/- 37 km/s to 243 +/- 79 km/s). Most of the jets with velocities > 450 km/s was registered at the solar cycle maximum.
