Different Sources of 10‐ to 30‐day Intraseasonal Variations of Autumn Snow over Western and Eastern Tibetan Plateau
Abstract Using the latest daily Moderate Resolution Imaging Spectroradiometer satellite snow cover data, the present study reveals distinctly different sources of 10‐ to 30‐day intraseasonal snow cover variations over the western and eastern Tibetan Plateau (TP) during September–December. The intras...
