I will not be pushed, filed, stamped, indexed, briefed, debriefed or numbered. My life is my own.

Originally posted by Serial_Apologist View PostNot absolutely sure, but the fact that that band of cloud stretched right across the country, and in a straight line, more-or-less, suggested a mid-tropospheric jet stream cloud layer, at somewhere between 10,000 and 14,000 feet.
I didn't really get warm and cold fronts until I saw some stright line edged banks of cloud from above in a plane. I think the first time I noticed it was on a flight into Stockholm.
Often clouds are more like little islands when viewed from a plane window, and sometimes there are really big one ones - but the straight edge lines are interesting too.

The best place to see them is on aerial photographs at sufficient distance from Earth to show the distinct regularly associated with bands of cloud which are in turn associated with frontal systems. Seen from above in this way, the edge, where the cloud band dissipates out at its highest level of outflow, can give the illusion of the whole cloud layer or ribbon consisting of a homogeneous mass throughout, whereas in fact what is concealed underneath from that vantage point is a whole lot of complexity, with several layers of cloud, sometimes separated, often merged, concealed from view.
