Traveling microbursts were experimentally simulated by salt water dropping from a tank settled in water flow. The density dependence of its property was investigated. The flow pattern of the traveling microburst was filmed with a hi-speed camera and the velocity field was measured with a dynamic PIV method. The maximum horizontal velocity of the traveling microburst at the windward side depended on the density of the salt water whereas that at the leeward side did not depend of the density well. Such density dependence was not described through the scaling law for the stationary microburst.
