英文摘要Soil moisture (SM) during the vegetation growing season largely affects plant transpiration and photosynthesis, and further alters the land energy and water balance through its impact on the energy partition into latent and sensible heat fluxes. To highlight the impact of strong vegetation activity, we investigate global SM-climate interactions over the peak growing season (PGS) during 1982-2015 based on multisource datasets. Results suggest widespread positive SM-precipitation (P), SM-evapotranspiration (ET), and negative SM-temperature (T) interactions with non-negligible negative SM-P, SM-ET, and positive SM-T interactions over PGS. Relative to the influence of individual climate factors on SM, the compounding effect of climate factors strengthens SM-climate interactions. Simultaneously, variations of SM are dominated by precipitation from 50 degrees N toward the south, by evapotranspiration from 50 degrees N toward the north, and by temperature over the Sahara, western and central Asia, and the Tibetan Plateau. Importantly, the higher probability of concurrent SM wetness and climate extremes indicates the instant response of SM wetness to extreme climate. In contrast, the resistance of vegetation partially contributes to a consequent slower response of SM dryness to extreme climate. We highlight the significance of the compounding effects of climate factors in understanding SM-climate interaction in the context of strong vegetation activity, and the response of SM wetness and dryness to climate extremes.
