Hawaii is a unique land. In addition to being located in the middle of the Pacific Ocean, it can be characterized by one key peculiarity: The largest island (Hawaii), covering an area of about 3,700 square miles, is home to 10 different precipitation belts. On the western coast, there are areas where it does not rain more than 20 inches per year, while on the eastern coast, some areas receive more than 250 inches of rain per year. Such an extreme variability of rainfall in such a small area is not only caused by orographic terrain(mountains influencing rainfall), with a difference in altitude by up to 4000 meters, but is also a result of the intensive production of sensible heat (the form of heat energy that we can feel),from a dehydrated landscape. Both the areas with high rainfall and the dry foothills of volcanoes are significantly damaged by water erosion due to the degraded landscapes.
Based on the new water paradigm (see endnote), it can be argued that the dried out mountain range landscape releases a vast amount of sensible heat into the atmosphere, because of increased temperatures from the sun’s rays heating up unvegetated areas. This sensible heat, along with the orographic terrain, hinders the passage of humid air masses over the ridges of the mountain range to the west of the island and therefore prevents precipitation. This causes the concentration of vertically forming clouds on the eastern side of the island, resulting in frequent and intense rainfall, erosion and local flooding. This phenomenon is directly related to the occasional, yet dramatic intense bursts of rain on the slopes of the mountain range with low annual rainfall, as well as the areas with intense rainfall in eastern parts of the island.
