Abstract

The protection method involves introduction of negative electric charges in the atmospheric layer for 1-20 days and nights along the probable path where the cyclonic storm is brewing until the cyclonic storm comes to the protected region.

Description

The zone prevents the method for whirlwind storm

The present invention relates to meteorological field, more definite theory belongs to the method that the zone prevents the whirlwind storm, can be used for protection and be subjected to middle latitude or Hurricane storm, comprising the zone of the attack of hurricane.

For weaken wind-force known be to remove to the cloud cluster of whirlwind storm with aircraft in stage that hurricane forms to broadcast icing agent and (for example consult Curbinghurricanes-the chance[Interview with Dr.Robert H.Simpson in natural test, Director of the national Hurricane Centre) " USNews and World Report ", 1969,67 No 34-36).Can reach a conclusion by measuring, the place after the whirlwind storm attacks has reduced wind speed significantly certain period.

The shortcoming of institute's using method is that efficient is low in this test, promptly causes wind speed to reduce after the whirlwind storm attacks rather than in the hurricane formation stage.Other shortcoming of this method is to suppressing complicated operation, the danger and expensive of whirlwind storm.

The objective of the invention is to propose the method that a kind of zone prevents the whirlwind storm, utilize electric charge that the influence of whirlwind storm state is enabled to alleviate the destruction of whirlwind storm in the method even destroy this whirlwind storm or change its moving direction.

The purpose that is proposed reaches like this; prevent in the method for whirlwind storm in the zone; according to circumstances in claimed zone; in atmosphere, introduce negative volume charge along the path that the whirlwind storm may pass through; lasting 1-20 round the clock; come claimed zone up to this whirlwind storm expection, so that influence the energy of air eddy motion.

The method that is proposed is the electrodynamics pattern according to vortex cyclone, particularly is because the interaction of the positive volume charge of the vertical component in earth's magnetic field and the air in the atmosphere excites and strengthens proposes according to the vortex cyclone cyclonic motion.

In this pattern, the vertical component intensity B in the moment of momentum of whirlwind and earth's magnetic field and the positive density of volume charges 9+ of air are linear.

M～Bz.Q ⁺ (I)

According to this pattern, reach hurricane and form the stage, strengthen whirlwind under the condition of some critical value that surpasses the positive density of volume charges could realize, can reach above the air layer of these numerical value in having the atmosphere of minimum electrical conductance, the troposphere above the ocean of earth low latitudes particularly, reach at most at the absolute humidity of this place's air and the air ion of band water, the tip on the face of land is that the mobile charge source in the atmosphere is minimum.Draw by relational expression (1),, must reduce positive charge density in the air in the atmosphere in order to weaken vortex cyclone.

According to these principles, the method that is proposed is characterised in that, in atmosphere, introduce negative electrical charge by this way in case make its reach atmosphere and in and the positive charge that in atmosphere, exists, cause and keep vortex cyclone.Should before the whirlwind storm arrives claimed zone, negative electrical charge be introduced in the whirlwind along whirlwind storm mobile route, thus each charge generators to be configured in the whirlwind storm may the path of mobile path on.In order to destroy the whirlwind storm, in atmosphere, introduce can with the positive lotus Q of whirlwind ₊The negative electrical charge Q that relatively intends of absolute value _-, the value of whirlwind positive charge such as following conditional are estimated.

Q ₊≈πR ²HQ ₊ (2)

R-whirlwind radius wherein,

H-comprises the air layer height of positive charge,

Q ⁺-in the mean charge density at whirlwind cloud cluster center.

In developing into the time T in hurricane stage, whirlwind is incorporated into the negative electrical charge Q in the atmosphere _-By under show equation decision $Q_{-}=T\frac{d{Q}_{-}}{\mathrm{dt}}$

Wherein,

Introduce the speed of negative electrical charge to atmosphere.

In institute's extracting method, the enforcement of introducing negative electrical charge in atmosphere utilizes the electrizer of a ground connection, and for example its operation principle is to utilize the conductive surface or the tip that apply high potential to make air ionization.

Target value parameter in equation (2) and (3) is as follows:

R=50 kilometer-form the mean radius of the Hurricane in stage at hurricane,

Q ₊=0.1 kil. ocoulomb logical sequence/cubic meter--in the heart mean charge density in cloud cluster,

The H=1 kilometer--comprise the cloud layer calculated thickness of positive charge,

T=20 is round the clock--and vortex cyclone develops into required maximum time in hurricane stage. $\frac{d{Q}_{-}}{\mathrm{dt}}=2\×{10}^{-3}$ Kil. ocoulomb logical sequence/second--produce the speed of negative electrical charge in atmosphere, this electric charge is to utilize the electrizer by the ground connection of conductor principle of corona discharge work to produce.

The advantage of this method is:

Can destroy the whirlwind storm fully or change its moving direction,

This method is to resident and all operator safety, promptly unnecessary aircraft flight or fire a rocket to whirlwind,

Compare with known method, greatly improving under the situation of functioning efficiency, reduce the organization that the zone prevents the whirlwind storm relatively.

This method embodiment

On August 25th, 1993 is at the C of the whirlwind vortex that is in large-scale middle latitude _AHKT-H _ETep6ypraCity (Russia) (position of whirlwind storm is created on the Fig. 1 that take to be drawn by spaceship), this whirlwind storm southeastward direction moves and estimates at 93.8.27 to the urban district, Moscow.

19 days on the 25th August in 1993, input was positioned at from Moscow from the charge generators (electrizer) of 25 kilometers of northern borders in order not make this whirlwind storm through Moscow.The whirlwind vortex was in the Moscow north and located (Fig. 2) for 300 kilometers on August 26th, 1993.

On August 27th, 1993, the spiral conformation disappearance (Fig. 3) of whirlwind storm is comprising the Russian central region in Moscow, generally has the good climatic region of local thunder and lightning and heavy rain.Air pressure reduces redistribution.The abatement of wind.

Claims (1)

1. a zone prevents the method for whirlwind storm; it utilizes and can measure influence to the eddying motion of air; it is characterized in that; in claimed zone; along the path that the whirlwind storm may pass through; introduce negative volume charge to atmosphere, lasting 1-20 is round the clock until this whirlwind storm is come claimed zone.
