Effects of the inter-annual precipitation changes on plant growth are widely concerned. However, it is not well-known how plant growth responds to intra-annual precipitation regime changes. Here, we compiled reanalysis climate data (ERA5) and four satellite-based vegetation indices, including the Normalized Difference Vegetation Index (NDVI), the Enhanced Vegetation Index (EVI), the Solar-induced Chlorophyll Fluorescence (SIF), and the Modified Triangular Vegetation Index (MTVI2), to evaluate the response of alpine grasslands (including alpine meadow and alpine steppe) to the change of precipitation regimes, especially to the intra-annual precipitation regimes on the Tibetan Plateau. We found monthly precipitation over the alpine steppe significantly increased in the growing season (May\u2013September), but precipitation over the alpine meadow significantly increased only in the early growing season (May\u2013June) (MJP) during the past four decades (1979\u20132019). The inter-annual plant growth (vegetation indices changes) on the alpine meadow was dominated by temperature, but it was driven by precipitation for the alpine steppe. On the intra-annual scale, the temperature sensitivity of the vegetation indices generally decreased but precipitation sensitivity increased during the growing season for both the alpine meadow and steppe. In response to the increase in MJP, we found the temperature sensitivity of the vegetation indices during the mid-growing season (July\u2013August) (MGNDVI, MGEVI, MGSIF, and MGMTVI2) in the alpine meadow significantly increased (p &lt; 0.01) while its precipitation sensitivity significantly decreased (p &lt; 0.01). We infer that more MJP over the meadow may be the result of enhanced evapotranspiration, which is at the expense of soil moisture and even induces soil \u201cdrought\u201d in the early growing season. This may be to elevate community water acquisition capacity through altering root mass allocation and community composition, consequently regulating the divergent climate sensitivities of vegetation growth in the mid-growing season. Our findings highlight that it is inadequate to regard precipitation as an indicator of water availability conditions for plant growth, which may limit our understanding of the response and acclimatization of plants to climate change.<\/jats:p>","DOI":"10.3390\/rs14102484","type":"journal-article","created":{"date-parts":[[2022,5,22]],"date-time":"2022-05-22T07:13:57Z","timestamp":1653203637000},"page":"2484","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Divergent Climate Sensitivities of the Alpine Grasslands to Early Growing Season Precipitation on the Tibetan Plateau"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1975-7834","authenticated-orcid":false,"given":"Zhipeng","family":"Wang","sequence":"first","affiliation":[{"name":"Lhasa Plateau Ecosystem Research Station, Key Laboratory of Ecosystem Network Observation and Modeling, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing 100101, China"},{"name":"School of Water Conservancy and Hydropower, Hebei University of Engineering, Handan 056038, China"}]},{"given":"Xianzhou","family":"Zhang","sequence":"additional","affiliation":[{"name":"Lhasa Plateau Ecosystem Research Station, Key Laboratory of Ecosystem Network Observation and Modeling, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing 100101, China"},{"name":"College of Resources and Environment, University of Chinese Academy of Sciences, Beijing 100190, China"}]},{"given":"Ben","family":"Niu","sequence":"additional","affiliation":[{"name":"Lhasa Plateau Ecosystem Research Station, Key Laboratory of Ecosystem Network Observation and Modeling, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing 100101, China"}]},{"given":"Yunpu","family":"Zheng","sequence":"additional","affiliation":[{"name":"School of Water Conservancy and Hydropower, Hebei University of Engineering, Handan 056038, China"}]},{"given":"Yongtao","family":"He","sequence":"additional","affiliation":[{"name":"Lhasa Plateau Ecosystem Research Station, Key Laboratory of Ecosystem Network Observation and Modeling, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing 100101, China"},{"name":"College of Resources and Environment, University of Chinese Academy of Sciences, Beijing 100190, China"}]},{"given":"Yanan","family":"Cao","sequence":"additional","affiliation":[{"name":"School of Earth Science and Engineering, Hebei University of Engineering, Handan 056038, China"}]},{"given":"Yunfei","family":"Feng","sequence":"additional","affiliation":[{"name":"Department of Resource Management, Tangshan Normal University, Tangshan 063000, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6768-8255","authenticated-orcid":false,"given":"Jianshuang","family":"Wu","sequence":"additional","affiliation":[{"name":"Institute of Environment and Sustainable Development in Agriculture, Chinese Academy of Agricultural Sciences, Beijing 100081, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"29720","DOI":"10.1073\/pnas.2002314117","article-title":"Forest and woodland replacement patterns following drought-related mortality","volume":"117","author":"Batllori","year":"2020","journal-title":"Proc.
