In recent years, cases of destructive hurricanes have increased, which is caused by climate change. Given the undesirable destruction that hurricane wind generates when the hurricane reaches the coast, we propose here a variant of active influences in the atmosphere in order to reduce the wind speed at the epicenter of the hurricane and its transfer to a tropical storm. The average hurricane's power is about ten to fifteenth degree. This power is due in large part to the kinetic energy of the wind movement with high speed. Therefore, the article proposes to brake the speed of a hurricane by adding a few hundred tons of sand to the epicenter of the hurricane, in the atmosphere in the region of the largest hurricane wind, at an altitude of several kilometers above the earth. The mechanism of braking the hurricane wind is based on the friction of air on the large total surface of all the added grains of sand, sand is a finely dispersed non-hygroscopic particles. Part of the energy of the hurricane must be spent on the movement of sand (its movement) and mainly on overcoming the frictional force that arises at the boundary of each grain of sand with air. These more active actions should be taken when the hurricane is above the ocean, and it has not yet reached the coast, about a day or more before that. For example, it is possible to drop several tons of sand from an airplane over the area occupied by a hurricane, by analogy with methods active influences on clouds for precipitation intensification. It is also possible to deliver this sand with rockets to the optimal hurricane area in order to provide the maximum conditions for the dissipation of turbulent energy. Some principal calculations were performed in this paper. Lognormal distribution of sand grain sizes in introduced that is typical for natural sands, and also the influence of acoustic vibrations, turbulent pulsations of air flow and other affects are taken into account. Presented estimates and calculations show that relatively small masses of sand of about 1000 cubic meters or more can effectively reduce by 20…30% the hurricane's energy per 1−2 days.
