Combining the satellite￢ﾀﾐbased enhanced vegetation index MODIS EVI with a novel location￢ﾀﾐspecific definition of the growing season, we quantify drought impacts on sub￢ﾀﾐseasonal vegetation activity and the subsequent recovery in the Northern Hemisphere. Drought legacy effects are quantified as changes in post￢ﾀﾐdrought greenness and sensitivity to climate. We find that greenness losses under severe drought are partially compensated by a ￢ﾈﾼ+5% greening within 2￢ﾀﾓ6 growing￢ﾀﾐseason months following the droughts, both in woody and herbaceous vegetation but at different timings. In addition, post￢ﾀﾐdrought sensitivity of herbaceous vegetation to hydrological conditions increases noticeably at high latitudes compared with the local normal conditions, regardless of the choice of drought time scales. In general, the legacy effects on sensitivity are larger in herbaceous vegetation than in woody vegetation.</p 580 570 Ecology QC801-809 Geophysics.
