Wind dependency of the number concentration, the salt-mass distribution, and the vertical distribution were studied. The particle number concentration, in an average, increased with increasing wind speed. The large amount of sea-salt particles was often found at the area where squalls or rains were frequently observed. The relation between the mean particle number concentration and wind speed may be approximately expressed by an exponential function. The wind factor is slightly larger for larger salt masses than for smaller ones. The mean salt-mass distribution of each class interval of from log m=0.5 to log m=2.5 is presented for various wind forces. The vertical distribution of the mean particle number concentration is approximately distributed by a straight line on the logarithmic diagram of log θ-log z, as theoretically expected. The observed vertical gradients are nearly in agreement with the theoretical ones for the class of small salt mass in wind forces 0-1 and 2, though the observed gradients are slightly stronger than the theoretical ones for three classes of salt mass in wind forces 3, 4 and 5.}, pages = {55--72}, title = {Observations of the Distribution of Giant Sea-Salt Particles in the Sea-Surface Boundary Layer}, volume = {20}, year = {} }
