A Study of the Relationship between Low-level Jet and Inversion Layer over an Agroforest Ecosystem in East China Plain?


doi: 10.1007/s00376-000-0011-z

  • The relationship between the super-low-level jet (LLJ) and inversion layer over an agroforest ecosystem on the Huang-Huai-Hai plain in the eastern China is studied by means of a time-independent K-closure model. It is found that the intensified inversion near the surface of a luxuriantly growing agrofor-est ecosystem leads to the formation and development of the LLJ, the more intense the inversion, the strong-er is the LLJ. The critical value of inversion intensity index for the LLJ formation is 0.75℃/ 100 m, which relates to the necessary geostraphic wind velocity of 6.0 to 10 m/ s at the top level of the model The numer-ical calculations show that the roughness length of the underlying surface has considerable effects on the LLJ structure.

The critical value of inversion intensity index for the LLJ formation is 0.75℃/ 100 m, which relates to the necessary geostraphic wind velocity of 6.0 to 10 m/ s at the top level of the model The numer-ical calculations show that the roughness length of the underlying surface has considerable effects on the LLJ structure.
