After a decade of monitoring tropical cyclones, it was found that when the storms are moving through the ocean water mixed with fresh water from flowing into rivers, it does increase the intensity of hurricanes and typhoons. Let the probability that the storm will be held in the region of cluster of fresh water, is only 10-23%, but if it happens, the increase in the intensity of 50%.
The observed features can significantly improve the mechanism of forecasting hurricanes, depending on the coordinate origin of climatic events. Most likely, it will be useful in places where large freshwater rivers flow into the ocean, and where regularly receive higher rainfall. Earning, forecasting growth of intensity of hurricanes will save from the ravages of about 60% of the world population living permanently in areas prone to tropical storms.
Under the influence of fresh water from rain or rivers in the ocean at a depth of 50 m barrier layer is formed which does not allow ocean water to cool quickly. Warm water is perfect for fueling the cyclones and tornadoes. Their destructive power is measured in cubes intensity. Knowing the rate of advance of tropical systems and the availability of fresh water there, it will be possible to prevent more deaths and to avoid damage.
