Analysis of 7Be activity values measured from 63 IMS stations worldwide from 2001 to 2015. Observed 7Be global seasonal variation as an expression of atmospheric cell migration, ITCZ and HFCZ. Reconstruction of a global 7Be concentration map over time. Correlation between 7Be global patterns with tropopause height, Walker circulation, SSW, SEP and QBO. Onsets of 7Be activity concentrations as early warning indicator for emerging El Niños and Indian monsoons.
