The main objective was to determine the relationship between soil parameters and obscuration features of clouds produced by static detonations of munitions and explosives in the humid tropics during the dry season. A combined total of forty-one 15-pound TNT charges and 105- and 155-millimeter high explosive rounds were detonated statically in various types of vegetation at three sites, including an ocean beach site. In addition, six tube-delivered 105-millimeter, high explosive, M1 rounds were fired during the dry season and six during the wet season to collect comparison data. It was concluded that the amount of obscuration in the humid tropics is determined mainly by a combination of two factors: windspeed and soil moisture. 收起
