a Accuracy, b threat score, and c Heidke’s skill score obtained under the WJRA and WOJRA settings for the whole period from July 2019 to March 2020 (black solid line) and for the case of magnetospheric quiet condition with daily maximum K < 4 (blue dashed line). Error bars represent the sensitivity of the values derived from one hit event being moved from or into the true negative case, i.e., TP and TN in Eqs. (1, 2, 3, 4) are replaced by TP ± 1 and TN  1, respectively
