1. Introduction From theoretical ( Rhines 1975 ) and numerical ( Williams 1978 ) studies, it is well known that in the presence of the meridional planetary vorticity gradient β , an upscale energy cascade generates zonal jets in two-dimensional turbulence. Numerical simulations of quasigeostrophic (QG) turbulence show that if the width of the baroclinically unstable region of the initial flow is greater than the inverse of Rhines’s cascade-arrest scale, ( β /2 u rms ) 1/2 , multiple zonal jets

1. Introduction The strength, shape, and latitude of the tropospheric jet stream vary spatially and temporally in a wide range of time scales, affecting the regional climate. The properties of the jet, including its short-time-scale variability, are affected by the surrounding conditions, such as the season ( Lindzen and Hou 1988 ; Kim and Lee 2004 ), changes in the diabatic forcing ( Son and Lee 2005 ), sea surface temperatures ( Lu et al. 2010 ), and stratospheric conditions ( Polvani and

solution of a verylong-term numerical integration from a state of rest exhibits many of the observed characteristics of thebroad-scale monsoons at 75-E. This later solution is used as a lateral forcing for the low-level jet simulations over the Arabian Sea-Indian Ocean. The numerical model presented here is a one-level primitive equation model with a detailed bottomtopography and a one-degree latitude grid size. Results of several controlled numerical experiments suppressing or including
