The 9th March 2021 there was a configuration in the clouds which a perfect example of how streamlines are studied in fluid dynamics and wind tunnels. (Sorry for the shaking, Youtube has removed the stabilizer tool). 
In 2004 and 2005 I used a wind tunnel to study the aerodynamic properties of biological aerosols studying the behaviour of pollen grains following streamlines at different wind speeds. And also, I studied the impact that such aerodynamic behaviour following streamlines exert over the sampling efficiency of different methods applied to monitor their concentration.
The most common way to visualize streamlines in a wind tunnel is to use plumes of smoke. The configuration of those plumes of smoke indicate the characteristics of the airflow in which those are embedded, and even show the path followed when encountering an object, also used to monitor drag in the design of plains or cars. In the open environment, we can use the shape of clouds similarly as the plume of smoke in a wind tunnel, to understand the atmospheric conditions dictating their configuration.

- In a broader scale, such configurations can be seen from the ground as well as from satellite imagery. In my line of research since 2013 on Climate developments and atmospheric dynamics, I have applied my experience to study the shape of clouds in atmospheric circulation.

- Based on the result from my analyses I offered an interpretation over the global circulation and its implications in Climate developments.
In this line of research it has been proposed a description over current developments for local and global dynamics. Such description offers an explanation for the development of warm and cold anomalies as Rayleigh-Taylor instabilities induced by an increase in the atmospheric energy load at mid-latitudes, carried by water vapour forcing intrusions over the Poles, promoting an increase in global mixing resulting in a wobbly Polar Jet Stream and extreme and sudden changes in weather conditions.
