中文摘要
这项研究的目的是在海边的沙漠里造雨。在沙漠地区没有云,因此,干冰或银碘催化是不可能的。我们的想法是通过加速海水的蒸发来制造云,把黑色的物质放在海面上。它将太阳能100%吸收在海面上,不会将其反射回太空,也不会穿透到海洋深处。海面变得非常热,蒸发增加。蒸发的水分必须被转移到沙漠上,否则,它会在夜间落入大海。在沙漠表面放置黑色物质,太阳能吸收率比不放置黑色物质时增加。它100%吸收太阳能,沙漠表面变得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,这个区域变成低压。海面上的水汽具有高压,在上升气流的牵引下,向沙漠低压区移动,向上移动。在高空中,由于绝热膨胀,水汽被冷却,形成云和雨。几种材料在室外和暗室实验中进行了测试,观察到蒸发增加28-41%。几种沙漠沙的太阳光反射率为30- 70%,平均吸收率为1.5- 3倍,但较高的吸收率并不能保证降雨。在研究的这个阶段,海洋上的黑色区域和沙漠上的黑色区域之间的最长距离还没有确定。
英文摘要
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.
