DESCRIPTION:There are many observations of cloud patterns for the three-di
 mensional internal waves in the lower atmosphere\, which are modelled by t
 he two-dimensional Benjamin-Ono (2DBO) equation with initially truncated a
 nd bent line solitary waves. The Whitham modulation theory is employed\, a
 nd the analytical results are confirmed numerically. Sometimes\, when the 
 variation in the transverse direction is not weak\, the 2DBO model has to 
 be generalized to the isotropic situation. We further propose the Benjamin
 -Ono-Benney-Luke equation to describe these wave phenomena.
