Updraft curtains
From Glossary of Meteorology
updraft curtains
Long narrow sheets of warm air rising from a heated surface.
These are
also called microfronts because of the rapid temperature changes measured when these advect past fixed sensors. Updraft curtains are surface layer phenomena that gradually merge and change shape into boundary layer thermals as they rise higher into the mixed layer.
