Abstract: Assimilating the atmospheric fluid with a complex fluid and c<strong>on</strong>sidering that the<br />
fluid particles dynamics takes place <strong>on</strong> c<strong>on</strong>tinuous and n<strong>on</strong>-differentiable curves we build<br />
a new theoretical model of atmospheric vortex. This theory enables us to perform a good<br />
approach of dynamics both <strong>on</strong> a predictable scale (that corresp<strong>on</strong>d in our model with a<br />
differentiable scale) and an unpredictable scale (that corresp<strong>on</strong>ding at undifferentiated<br />
scale). The global visi<strong>on</strong> of dynamics is realized into an atmospheric fluid c<strong>on</strong>sidering that<br />
until now was used <strong>on</strong>ly a deterministic models or stochastic models. Furthermore it is<br />
shown that the vortex source is given by a complex fluid dynamics <strong>on</strong> the n<strong>on</strong>differentiable<br />
scale. Validati<strong>on</strong> of the theoretical model was based <strong>on</strong> correlati<strong>on</strong>s with<br />
meteorologically data. An immediate perspective is to taking into account the tropospheric<br />
particles distributi<strong>on</strong> with altitude, such as a LIDAR system (Light Detecti<strong>on</strong> and<br />
Ranging), with a high spatial and temporal resoluti<strong>on</strong> (3.5 meters/ from 30 sec<strong>on</strong>ds to 1 or<br />
5 minutes). Thus, the variati<strong>on</strong> of aerosols distributi<strong>on</strong> in the atmosphere (up to altitudes of<br />
10 - 12 km) and complex variati<strong>on</strong> of the fluid particle distributi<strong>on</strong>s (according to<br />
theoretical model) will be highlighted and correlated for validati<strong>on</strong> of theoretical model.<br />
Key words: vortex, complex fluid, n<strong>on</strong>-differentiability, atmospheric dynamic.<br />
