Rainmaking in Seashore Desert

这项研究的目的是在海边的沙漠里下雨。沙漠地区没有云，因此，用干冰或银碘播种是不可能的。我们的想法是通过加速海水蒸发来形成云，通过在海面上放置黑色物质来实现。它100%地吸收海面上的太阳能，不会反射回太空，也不会渗透到深海。海面变得很热，蒸发量增加。蒸发的水分必须转移到沙漠上，否则，它会在夜间落入大海。在沙漠表面放置黑色材料，与没有黑色材料相比，增加了对太阳能的吸收。它100%吸收太阳能，沙漠表面比没有黑色物质时更热。然后，表面上的空气变热，膨胀，变轻，上升，区域变得低压。海面上的水汽是高压的，在向上气流的作用下，向沙漠上的低压区移动，并向上移动。在高空，噪声被绝热膨胀冷却，形成云和雨。几种材料在室外和暗室试验中，蒸散量增加了28-41%。几种沙漠沙对Soler的反射率为30-70%，平均吸收1.5-3倍，但较高的吸收率不能保证降雨。在现阶段的研究中，海上黑区和沙漠黑区之间的最长距离还没有确定。

The aim of this research is to make rain in a desert near sea. There is no cloud in desert area, therefore, seeding by dry ice or silver iodine is not possible. Our idea is to make cloud by accelerating evaporation of sea water, by putting black material on the surface of the sea. It absorbes solar energy 100% on the sea surface, without reflecting it back to the space nor penetrating into deep the sea. The sea surface becomes very hot and evaporation is increased. The evaporated moisture must be moved onto the desert, otherwise, it falls down into the sea at night. Putting black material on desert surface, solar energy absoption is increased compared with no black material exists. It absorbes solar energy 100% and the desert surface becomes hotter than without the black material. Then air on the surface becomes hot and expands and becomes lighter and goes up and the area becomes of low pressure. The moisture on the sea surface is of high pressure and moves to low pressure area on the desert, and moves upward, being pulled by the upward air stream. In the high sky, the noisture is cooled by adiabatic expansion and make cloud and rain. Several materials were tested outdoors and in the dark room experiments, and 28-41% increase of evapopration was observed. Soler reflection by several kinds of desert sand were measured to be 30-70%, with means absorption by 1.5-3times is expected, although higher absoption does not gurantee rain fall. The longest distance between black area on the sea and the black area on the desert was not defined yet at this stage of the research.
