The Problem

Hurricanes are one of the natural disasters that can destroy a city. Hurricane are formed over warm water near equators and not on land, but in unusual global climate change they reach lands as well. Like other natural disasters there is no way to prevent or stop them. Since they can cause billions of dollars of damage, preventing them would worth the investment and research.

Solution

Hurricanes are cyclones caused by rising warm moist air where the water is warm around the equator. So if the temperature of the rising air can be affected or the air flow can be disturbed then the power of the hurricane can be reduced. A possible solution would be to use explosives that spread heat at the top of the hurricane in large volume or spread coolant at the bottom of eye of hurricane. This should disturb the structure and stop it building up. Hurricanes have no more or less power than the air in a hot room where there is no wind and it appears calm. The air molecules in the room is also moving at the same speed as a hurricane, the difference is that in a hurricane they all move in the same direction cause the wind to have power and as the result it causes suction with the same force as its wind. That is what makes it powerful, not the energy itself. So it is only necessary to disrupt the flow of the structure and not dampen the force.

The problem is a amount of energy required to defuse a horricane. So at present time it cannot be achieved. It can be tested on small tornados first. However, it is an idea that should be looked into for future.
