Cloud Streets
November 7, 2011


Howard Stout took this picture at his home in Santa Fe. 

Here is another view of cloud streets from space. 

When the low-level air begins to rise, clouds can form.  Some days there is a layer of stable air above, and that limits the vertical extent of the convection.  If the wind is fairly uniform the clouds can form “streets”.  You’ll get parallel lines of clouds alternating with the clear skies.  These gaps are caused by the rising/sinking air produced by the rotating horizontal cylinders in the atmosphere.
