CONCENTRATION DISTRIBUTION IN A PLUME RELEASED OVER WATER.

Continuous release of tracer over water shows relative small variations of instant plume width. With temperature difference air/ sea. Concentration variation relative to center of gravity in a cross-section show tendency of travelling lumps. Either concentrations are high throughout the cross-section, or they are low all over. The recent mass important is the tendency of high continuous near the center and low at the boundaries, or vice versa.
