Abstract

The air jets projected upwards convey the air to a point higher than the condensation point level, or raise the clouds. The fans cause air which is near the ground and is rich in humidity and condensation nuclei, to reach great heights comparatively quickly, thereby overcoming inversion layers and other blocking layers. The air thus lifted to a great height cools off below condensation point and forms clouds, causing a drop in temp. and an increased tendency to form rain. The fans are pref. fitted to the walls of a casing or a frame, and pivot on horizontal axes. The device may be used to bring rain to plains; to cause rain clouds to shed rain in order to prevent flooding further on; and is quickly effective.

Description

Die Ventilatoren 1 sind vorzugsweise an den Wänden eines Gehäuses 3 oder an einem Rahmen angeordnet und um waagerechte Achsen 4 schwenkbar. The fans 1 are preferably on the walls of a housing 3 or arranged on a frame and pivotable about horizontal axes 4.

Device according to claim 3, characterized in that the fans (1) are pivotable about a horizontal axis (4). Die Erfindung bezieht sich auf eine Einrichtung zur Wolken- und/oder Regenbildung. The invention relates to a device for cloud and / or Rain formation. Bisher wurde eine künstliche Wolkenbildung vom Boden aus durch Anreichern von nach oben gerichteten natürlichen oder künstlichen Warmluftströmungen mit Wasserdampf oder anderen Mitteln angeregt. Diese bekannten Verfahren haben den Nachteil, daß die Wolkenbildung sehr langsam vor sich geht, daß sie örtlich schwer zu binden ist, daß sie abhängig vom Aufwind sowie von Inversionsschichten ist und daß wegen der weiträumigen Zerstreuung nur ein sehr geringer Wirkungsgrad erzielbar ist. So far, an artificial cloud formation from the ground by enrichment upward natural or artificial warm air currents with water vapor or other means suggested. These known methods have the disadvantage that the cloud formation is very slow that it is locally difficult to bind, that it is dependent on the updraft as well as on inversion layers and that because of the large-scale dispersion only a very low level of efficiency can be achieved. Es ist ferner bekannt, Niederschläge aus vorhandenen Wolken dadurch zu erzielen, daß mittels Flugzeugen oder Raketen Kristallisationskerne, z. B. Silberjodid oder Eisenkristalle, in die Wolken gebracht werden. It is also known to create precipitation from existing clouds to achieve that by means of aircraft or missiles crystallization nuclei, z. B. silver iodide or iron crystals, are brought into the clouds. Damit ist jedoch nur eine kurzfristige Beinflussung der Wolken und ein geringer Wirkungsgrad erzielbar, da das Impfgut abgetrieben wird.However, this only has a short-term impact on the clouds and a low degree of efficiency can be achieved because the inoculated material is driven off. Erfindungsgemäß ist eine Wolken- und/oder Regenbildung unter Vermeidung der genannten Nachteile dadurch erzielbar, daß Ventilatoren mit senkrecht oder schräg nach oben gerichtetem Luftstrahl zum Transport von Luft über Taupunkthöhe bzw. zur Hebung von Wolken dienen. Durch die Ventilatoren wird bodennahe, an Luftfeuchtigkeit sowie Kondensationskernen reiche Luft relativ schnell in große Höhen gebracht, wobei auch Inversions- und andere Sperrschichten überwunden werden können. Auf diese Weise kann auf die Wolkenbildung mit einfachen Mitteln in gewünschter Weise, auch über eine beliebig lange Zeit eingewirkt werden. Die Erzeugung künstlicher Wolkenfelder kann z. B. dazu dienen, um nachts Ausstrahlungen zu verringern. According to the invention, the formation of clouds and / or rain is to be avoided the disadvantages mentioned can be achieved in that fans with vertical or aslant upwardly directed air jet for the transport of air above dew point height or to Serve to raise clouds. The fans are close to the ground, in humidity as well as condensation nuclei brought rich air relatively quickly to great heights, whereby Inversion and other barrier layers can also be overcome. In this way can on the cloud formation with simple means in the desired way, even about can be acted on for any length of time. The creation of artificial cloud fields can e.g. B. serve to reduce emissions at night. Die Anhebung der Wolken im Luftstrom hat ähnliche Wirkungen zur Folge wie der Stau von Wolken an einem Gebirge. Es wird eine Senkung der Temperatur im Wolkenfeld und damit eine erhöhte Niederschlagswahrscheinlichkeit erzielt. Durch eine Vorrichtung zum zusätzlichen Einbringen von Kondensations- und Kristallisationskernen in den Luftstrom der Ventilatoren ist es möglich, die Niederschlagswahrscheinlichkeit entsprechend zu beeinflussen. Raising the clouds in the air stream has similar effects like the accumulation of clouds on a mountain range. It will lower the temperature inside Cloud field and thus an increased probability of precipitation achieved. By a device for the additional introduction of condensation and crystallization nuclei In the air flow of the fans it is possible to reduce the probability of precipitation to influence accordingly. In der Zeichnung ist ein schematisches Ausführungsbeispiel der Erfindung dargestellt. In the drawing is a schematic embodiment of the invention shown. Wie die Figur zeigt, sind zur Wolken- bzw. Niederschlagsbildung erfindungsgemäß in Bodennähe Ventilatoren 1 aufgestellt, deren Luftstrahlen schräg nach oben gerichtet sind und an Luftfeuchtigkeit und Kondensationskernen reiche Luft rasch auf eine Höhe bringen, in der sie unter den Taupunkt abkühlt und ein Wolkenfeld 2 gebildet wird. As the figure shows, according to the invention for the formation of clouds or precipitation Set up fans 1 close to the ground, the air jets of which are directed obliquely upwards are and air rich in humidity and condensation nuclei quickly to one Bring height at which it cools below the dew point and a cloud field 2 is formed will. Auf das Wolkenfeld 2 gerichtete Luftstrahlen haben es an. Damit kühlt sich die Wolkenschicht ab, und in Verbindung mit den vorhandenen natürlichen oder künstlichen Beigaben von Kondensationskernen wird eine Regenbildung hervorgerufen. Air jets directed at cloud field 2 have it on. So that cools the cloud layer from, and in connection with the existing natural or artificial addition of condensation nuclei causes rain to form. Die Erfindung läßt sich also neben der Wolkenbildung zur Steigerung der Regenmenge z. B. über flachen Gebieten anwenden, sowie zur teilweisen Abregnung von Wolkenbänken zur Verhinderung von Überschwemmungen u. dgl. Der besondere Vorteil der Erfindung besteht in der schnellen und ortsgebundenen Erzielung der Wirkung sowie der Möglichkeit einer dauernden Beinflussung von Wolkenfeldern. The invention can also be used to increase cloud formation the amount of rain z. B. apply over flat areas, as well as for partial rain down of cloud banks to prevent flooding and the like. The special advantage the invention consists in achieving the effect quickly and locally as well as the possibility of a permanent influence of cloud fields.
