EquationsThe deformation of horizontal wind is defined as , where and , representing the derivatives of wind component. Because these derivatives vary greatly with the rotation of the coordinate system, so do and .[1] Stretching directionThe deformation elements and (above) can be used to find the direction of the dilatation axis, the line along which the material elements stretch (also known as the stretching direction). Several flow patterns are characteristic of large deformation: confluence, diffluence, and shear flow. {{visible anchor|Confluence}}, also known as stretching, is the elongating of a fluid body along the flow (streamline convergence). {{visible anchor|Diffluence}}, also known as shearing, is the elongating of a fluid body normal to the flow (streamline divergence).[1] See also
