With reference to the Subtropical Westerly Jet Stream (STWJ) and Indian winter weather, consider the following statements:
- The southward shift of the STWJ in winter helps steer Western Disturbances towards north and northwest India.
- Persistent winter fog and low clouds over the Indo-Gangetic Plain are mainly because the STWJ causes strong vertical mixing of the boundary layer.
- A strong STWJ can enhance the upper-level divergence ahead of a trough, aiding cyclogenesis/precipitation linked with Western Disturbances.
- The Tropical Easterly Jet (TEJ) is a dominant feature of Indian winter, shaping the core winter rainfall pattern.
