Abstract
One of the main features of the trade wind orographic cloud of the island of Hawaii wae found by SQUIRES and WARNER (1967) to be its cellular structure, particularly near the seaward edge. It was also found that these cells moved up the mountain slopes at approximately the speed of the wind. BLANCHARD (1967) discusses the shower characteristics of the rain observed on the slopes and suggests that the shower formations also progress up the slopes at a speed roughly equal to that of the wind.
