A "dynamic low" is produced by ________. a "dynamic low" is produced by ________. the strong descent of air very warm surface co
Dmitrij [34]
I believe that a 'dynamic low' is produced by The strong rise of air. 
A dynamic low develops if the air flow converges in lower regions of the atmosphere and diverges in altitude while the air is kept up in the center of the low. A low pressure area is a region on the topographic map where the atmospheric pressure is lower than that surrounding locations. Low pressure systems form under areas of wind divergence that occur in the upper levels of the troposphere.
