Abstract

The proposed method for suppressing a tropical cyclone (hurricane) consists in creating, for the purpose to reduce the energy of the cyclone, within the central zone of the cyclone, descending flows of atmospheric air are created that move along concentric circumferential paths at a distance of 10 - 15 km from the center of the of the cyclone and from each other, at a distance of 5 -10 km from the flows at the same path. To suppress the energy of the cyclone at the stage of its initiation, the central zone of the cyclone is bombard by vacuum bombs, which are dropped from an airship or another similar aircraft in order to affect the ascending air flows. The radius of the circle, the center ofwhich coincides with the center of the cyclone, in the zone of the bombardment must be no less than 10 km. The bombardment results in creating vacuum an the central zone of the cyclone, and this zone is filled with descending atmospheric aid from above and with ascending air from below. The motional energy of the air flows reduces when the air flows meet, and the air density and pressure at the central zone of the cyclone increase. The increase of the air pressure at the central zone results in the creation of lower and upper air flows that suppress the cyclone due to the redaction of the pressure difference at the central and peripheral points of the cyclone.

Description

Description of the invention

The useful model refers to the area of artificial influence on the weather conditions of those regions of the Earth, where powerful tropical cyclones (hurricanes, typhoons) periodically arise in the atmosphere, which have great destructive power, which leads to great losses to the population of these regions, and therefore, to prevent these losses , the idea (which is proposed) of weakening cyclones can be used by the combined efforts of the states of these risk regions, or by special units of the World Meteorological Service.

There is a known method of weakening hurricanes (1), which is aimed at implementing (in the cloud system of a hurricane) 70 countermeasures against the existing natural circulation (ascending movement) of the lower mass of the cloud towards its mountain. It is assumed: in order to suppress the energy of the hurricane, in its cloud central zone, reproduce the downward (reverse) movements of the upper layers of the cloud, which are carried out in series in concentric circles, located around the eye of the cyclone (hurricane) and at a distance of 10... 15 km, with a step (around the perimeter of the circle) of the places where Her weakening takes place, no more than 5...10 km and with a time interval (between series of actions) not exceeding the regeneration period of 12 upward movements in the cloud.

These downward motions are initiated (due to the instability of the internal energy of the cyclone itself) by a series of simultaneous explosions (eg, high-explosive bombs) around the "dock" of the cyclone. The creation of these "anti-circulation" measures can be carried out by vehicles flying above cloud systems.

Method (1) is the closest to what is claimed and chosen as a prototype of the tool.

The disadvantages of the prototype are: 1) Untimely determination of the deadline for measures to implement the procedure for suppressing circulation processes (ascending movements) in the cloud system of a hurricane (cyclone): according to the prototype, measures begin to be implemented during the already formed "eye of the storm" of the cloud system (the third stage of cyclone development) At this time, the cyclone (hurricane) reaches its apogee: according to (21), the difference in atmospheric pressure between the rear and the center of cyclone 29 can reach 14...17 hPa/100 km (and more), see Fig. 1a; in 2 ) Inefficiency of the distribution of the energy of cutting the high-explosive charge. It is known that the energy of a high-explosion explosion in the atmosphere is distributed spherically around the point of explosion, therefore, a small fraction (15...20905) of the energy of the explosion (that is, the fraction of the energy sphere of the explosion, which directed towards the earth's surface); C 3) The impossibility of modern aerial vehicles to carry out simultaneous bombardment of a large area c (circle area 15...25 km).

The useful model "Method of Weakening Tropical Cyclones (Hurricanes)" is based on the following task: - - in order to most fully weaken the energy of cyclones (hurricanes; typhoons) to develop measures to carry out actions to weaken the energy of cyclones at the early stages of their development (for example, at the stage of young cyclone"); - in order to increase the effectiveness of actions (during the implementation of measures to weaken the energy of cyclones), see to develop a method of involving natural conditions to create anticyclonic forces.

The essence of a useful model The method of weakening..." is a set of the following essential features sufficient to achieve a new technical result: for a more complete suppression of the energy of a cyclone (hurricane), the influence on "du ascending movements of the cloud mass of the cyclone (in its center) occurs at the beginning of the second stage of cyclone development -o (young cyclone") from the board of any flying machine (airship of special design or other) by bombardment (with special vacuum bombs) of the upper plane of the cloud system of the cyclone, while :z" the area of the bombardment circle above the center of the young cyclone" must have a radius of at least 10 km from its center, which will allow this bombardment to reproduce (above its center) a spatial vacuum cavity", which will first begin to be filled with oncoming flows: from below by upward flows of cloud mass, and from above by the downward flow of atmospheric air, which is over the cloud system of the cyclone, - at the same time, during their meeting, the kinetic energy of the flows decreases (neutralize each other) and in the "vacuum cavity" (9) the density of the atmosphere begins to increase, which leads to an increase (in its middle) of atmospheric pressure -1 (a "dense balloon" is formed), and, further, from it will develop ( after some time) two new (anticyclonic) movements: one-up, which will neutralize the downward movement of the upper (above the cloud system) (ee) 50 layers of the atmosphere, and the second (main) - downward, which will neutralize the upward movement of the cloud mass, and

T" will fill the central part of the cyclone, which will achieve a weakening of the total energy of the cyclone (due to a decrease in the pressure gradient between its center and the rear) and it will turn into a normal extratropical cyclone with a small storm energy.

For a more detailed clarification of the essence of the useful model, a drawing (see Fig. 1 and 2) and its 99 detailed description are offered. Explanation to the drawings (Fig. 1 and Fig. 2): c - Fig. 1a shows (conditionally) a barogram of pressures and flow lines in the surface sublayer of the cyclone; - Fig. 1b shows a schematic vertical section of a tropical cyclone in the mature stage, where: thick lines are the boundaries of the eye of the storm; thin lines are air flow lines; Si - cirrus clouds; Sv - cumulus-rain clouds; K - showers and thunderstorms; because - Fig. 2 shows a photo card of a "young cyclone" (made from space, see wrapper (21).

The initiation of actions related to the implementation of procedures to weaken tropical cyclones (hurricanes) unfolds according to orders issued by the regional meteorological service, which constantly monitors weather conditions in "risk areas" using special methods (overflight of the territories by airplanes, weather scouts, etc.): upon detection of the first signs of the development of a cyclone, a special airship (or other flying device) is sent to this region, which begins to barrage over the specified territory and monitor (instrumentally and visually) the development of the cyclone.

From the moment of determination (by the airship crew) of the location of the formation of the future center of the development of the cyclone, the airship is brought into drift mode (hovering) over this area, where the airship crew detects (visually) the moment when a coherent system is formed from the located squall clouds, which consists of narrow spiral strips , which coincide near the center of the cyclone. This is a stage of development - "young cyclone" |21.

At the beginning of the "young cyclone" stage (see Fig. 2), the airship crew begins (according to the established regulations) to bombard the upper layers of the cloud system above the center of the cyclone with vacuum bombs in the plane of a circle with a radius of at least 10 km and a step between explosions of up to two kilometers. 70 Shelling of a specified territory is carried out by salvo multi-barreled (of known design) artillery devices located (in a known manner) on board an airship. With each shot of the artillery device, the volley charge of the bombs is distributed (according to the technical data of the device) in a checkerboard pattern on the defined plane of the area under fire.

The effect of shelling of the cloud system of the cyclone is as follows: 1) From the beginning (at the places of explosions of vacuum bombs), a vacuum sphere appears, the energy of the explosion of which quickly spreads in all directions (spherically). This process continues until neighboring spheres begin to merge with each other. Thus, after some time, a spatial "vacuum cavity" with very low atmospheric pressure in its middle is formed above the center of the cyclone.

Then this "cavity" begins to be rapidly filled (absorbed) by the upward flows of the cloud mass of the cyclone (due to the absorption of the main part of the outflow mass, see Fig. 1b) and the downward flows of atmospheric air above the cloud system of the cyclone (see Fig. 1b). The energy of these opposing flows in the middle of the "cavity" is mutually excluded (the flows oppose each other). Thus, a large atmospheric mass accumulates in the "cavity", which leads to the emergence of a large atmospheric pressure in the "cavity" - a dense atmospheric sphere is formed"; 2 ) Further, (under this pressure) two main new (anticyclonic) movements with a large kinetic energy will begin to flow out of the "atmospheric sphere": one - downward, which will neutralize the upward movements of the center of the cloud system; the second - up, which will neutralize the downward movements of the upper layers of the atmosphere (located above the center of the cloud system).

The downward atmospheric movement from the "atmospheric sphere" performs two roles: first, it neutralizes the energy of the ascending "g"

From cloud mass flows, and, secondly, it fills the low-pressure zone in the center of the cyclone (gravity attracts the "dense atmospheric sphere" to the Earth's surface), thus, the pressures between the center and the back of the cyclone begin to equalize (the pressure gradient between them decreases ). And this leads to a decrease (or complete disappearance) of the energy M of hurricane winds.

The further fate of the cyclone (after performing the procedures to weaken it) can be different: it can turn into an ordinary extratropical cyclone, and after repeated bombardments it can either disappear or turn into an anticyclone (if the pressure of the "atmospheric ball" exceeds the atmospheric pressure behind the tropical cyclone ).

Thus, the idea of a useful model is based on physical foundations that make sense for its practical testing by the international community. "
