“…Numerous studies have demonstrated the power of SPEI in indicating drought and used it to analyze vegetation response to drought at different time scales (Gouveia et al., 2017; Ivits et al., 2016; Peng et al., 2019; H. Xu et al., 2018; Z. Zeng et al., 2021). The SPEI (SPEIbase v2.6) with a spatial resolution of 0.5° from Consejo Superior de Investigaciones Científicas was used in this study to quantify the magnitude, duration and extent of drought during the period from 1993 to 2018.…”

“…1). On the one hand, spring phenology strongly governs vegetation growth and soil water consumption in the growing season [11][12][13]18 , thus influencing drought recovery. On the other hand, changes in temperature and snow accumulation (snow water equivalent (SWE)), during the non-growing season can directly determine subsequent spring phenology through biological processes 19,20 , thus influencing drought recovery (Fig.…”

Widespread spring phenology effects on drought recovery of Northern Hemisphere ecosystems

The time required for an ecosystem to recover from severe drought is a key component of ecological resilience. The phenology effects on drought recovery are, however, poorly understood. These effects centre on how phenology variations impact biophysical feedbacks, vegetation growth and, ultimately, recovery itself. Using multiple remotely sensed datasets, we found that more than half of ecosystems in mid- and high-latitudinal Northern Hemisphere failed to recover from extreme droughts within a single growing season. Earlier spring phenology in the drought year slowed drought recovery when extreme droughts occurred in mid-growing season. Delayed spring phenology in the subsequent year slowed drought recovery for all vegetation types (with importance of spring phenology ranging from 46% to 58%). The phenology effects on drought recovery were comparable to or larger than other well-known postdrought climatic factors. These results strongly suggest that the interactions between vegetation phenology and drought must be incorporated into Earth system models to accurately quantify ecosystem resilience.

“…There are inconsistent conclusions about the effects of drought on phenology. Studies have shown that drought leads to earlier spring and autumn plant phenology in the Northern Hemisphere at mid and high latitudes [10,16]. However, it has been suggested that drought has caused a delay in spring phenology and an earlier autumn phenology in the Canadian Prairies [17]; has induced a delayed spring phenology in gr assland ecosystems, conversely; has brought about an advanced spring phenology within forest ecosystems across the Northeast China Transect [18]; and had induced a delayed spring phenology and an advanced trend in autumn phenology in Southwest China [19].…”

“…Studies have explored the effects of drought on vegetation phenology in ecosystems mainly on a regional or global scale [10,11,20] and have mostly used remote sensing data as the basis for statistical methods to invert plant phenological periods and thus identify the response of plant phenology to drought at the community or landscape scale [21]. Therefore, the results for analyses of phenological responses to drought have been inconsistent.…”

Clarifying the response of plant phenology to drought duration is helpful for accurately interpreting and predicting carbon sinks in ecosystems. Based on the response of different phenological periods of the dominant species Stipa krylovii to monthly, seasonal and semiannual time scale drought in the typical steppe of Inner Mongolia from 1983 to 2018, the results revealed that (1) the start of the growing season (SOS) was characterized by an advance-delay-advance pattern, and the heading stage (HOS), flowering stage (FOS) and end of the growing season (EOS) all showed consistent advanced trends, which provided additional insight into the conclusions of previous studies that found the SOS was advanced in arid and semiarid regions. (2) The response mechanism of the SOS to the timing of drought was not consistent. Among the response mechanism, the SOS was delayed because of January-February drought at different time scales, but advanced because of April drought at different time scales. The HOS/FOS was delayed by June-July drought at different time scales, and the EOS was advanced by August-September drought at different time scales. (3) More importantly, the SOS, HOS, FOS and EOS were affected by predrought and its persistence, and the effects were greater the closer to the phenological periods that drought occurred. (4) At the monthly scale, droughts in January, June and August were the critical drought periods affecting the SOS, HOS/FOS and EOS, while seasonal and semiannual scale droughts in February, June-July and September were the critical periods affecting the SOS, HOS/FOS and EOS. The results of this study enrich our understanding of how drought at different time scales affects different phenological periods, providing a basis for improving plant phenological models.
