Research on long-term climatic variation on the Chinese Loess Plateau has demonstrated that loess is mainly the dust deposits transported by the northern wind of the winter monsoon, and that the paleosol accreted by rather slow dust accumulation was closely related to a strengthened summer monsoon.
