A kind of intermittent turbulent flows which was observed using a hot wire anemometer and a platinum wire thermometer on tower in Beijing at night has been introduced . This turbulence flow produced by wind shear in the stable stratified flow is consist of some individual or a crowdof cold eddies .The temperature spectral power law of this turbulence lies between -2 and -5/3 so that the Cm value measured by various methods which correlate with scale size of eddies would be different.The mathematical representation of intermittent turbulent flows in the atmosphere was developed. The abrupt variance of temperature at the surface of cold eddies may cause a reflection of radio wave or sound wave , therefore the value of Cm measured by various methods such as radar,scintillometer,thermometer, would be different.
