25°N——50°N，110°E——145°E一带大气环流(200hPa)的年际变化与华北相应各月降水的年际变化有显著的正相关关系：(25°N——50°N，110°E——145°E)一带200hPa位势高度正异常，华北相应各月降水偏多，反之，当为负异常时，华北相应各月降水偏少。

A hybrid method is proposed to study microcosmic characteristics of nanofluid multiphase flows in a lattice Boltzmann approach. Multicomponent lattice Boltzmann model on fine mesh is used in regions where physical parameters, such as density and velocity change tempestuously, otherwise a single component one on coarse mesh is used.
