Figure 2

(a) Altitudinal patterns in mean LU dates for Androsace tapete (AT, open cycles), Stipa capillacea (SC, open invert-triangles), and Kobresia pygmae (KG, open triangles) in Damxung; the grey-shaded duration highlights the synchronization of LU with the ISM onset period (25 May to 24 June); different letters along altitude indicate significant differences in mean LU dates of 2007–2013 between altitudes at P < 0.05. (b) Annual variations in Kobresia’s LU dates of Damxung, ISM onset dates, rainfall onset dates, and 300-hPa wind speed in the ISM onset period during 2001–2013; the grey-shaded period is for our observed years. (c) Annual variations in Kobresia’s LU dates of Qumalai and Henan and related rainfall onset dates during 1989–2010.
