“…In the limit of negligible wind effects and temperature gradients, Eqs. (9) and (10) coincide with those derived previously by Kaladze and Tsamalashvili (1997) and Stenflo and Shukla (2009). This set of equations also conserves the wave energy integral, ∂E/∂t = 0 where…”

“…Such parametric generation of largescale zonal structures by high-frequency finite-amplitude IGWs has been investigated recently by Horton et al (2008) and Onishchenko and Pokhotelov (2012). The existence of the nonlinear IGWs in the form of two-dimensional smallscale vortices (i.e., roll-type structures) has been reported by Kaladze and Tsamalashvili (1997) and Stenflo and Shukla (2009). Recently, have shown that the finite temperature gradient can substantially modify the condition for the existence of vortex-type structures obtained in previous works.…”

Abstract. The effect of the wind shear on the roll structures of nonlinear internal gravity waves (IGWs) in the Earth's atmosphere with the finite vertical temperature gradients is investigated. A closed system of equations is derived for the nonlinear dynamics of the IGWs in the presence of temperature gradients and sheared wind. The solution in the form of rolls has been obtained. The new condition for the existence of such structures was found by taking into account the roll spatial scale, the horizontal speed and wind shear parameters. We have shown that the roll structures can exist in a dynamically unstable atmosphere.

Abstract. In this paper, we have investigated vortex structures (e.g. convective cells) of internal gravity waves (IGWs) in the earth's atmosphere with a finite vertical temperature gradient. A closed system of nonlinear equations for these waves and the condition for existence of solitary convective cells are obtained. In the atmosphere layers where the temperature decreases with height, the presence of IGW convective cells is shown. The typical parameters of such structures in the earth's atmosphere are discussed.
