چکیده
Soil moisture is an important variable affecting land surface and climate interactions. This study used cross-wavelet wavelet coherence methods to analyze the relationship between soil climatic factors in area based on data sequence corresponding meteorological observed of desert steppe Inner Mongolia. The results showed that had a relatively high- or low-value period for months even years. was significantly different slope positions layers. fluctuation mean decreased gradually with deepening depth. varied time scales. influence precipitation significant at scales 1–6 10–15 months, while air temperature stable continuous periodic scale months. Climate indexes Pacific region, Decadal Oscillation (PDO), North Atlantic index (NAO) were main controlling Mongolia strongly correlated primarily 4–7 (PDO) Indian Ocean basin-wide warming (IOBW) strong lag effect moisture.
