    Hello and good day to everyone. I am new here and not sure if this fits in this category. For a long time, I have been following the use of so-called "hail planes" intended to mitigate damage. In principle, I certainly understand the use of such measures, provided they are demonstrably effective. However—and this is my firm belief—their deployment significantly interferes with weather patterns. For years, I have observed that the region where we live is suffering from a massive decline in rainfall. To me, the cause is evident: at least three—and usually four or more—of these planes are in operation here, depending on the threat of hail. Let me briefly explain how they work, to the best of my knowledge as a layperson. The aircraft are equipped with external burners containing silver iodide. They fly close to the storm cells and ignite the burners. The aim is for the released silver iodide particles to act as crystallization nuclei, causing rain to fall much earlier or resulting in significantly smaller hailstones reaching the ground. From a distance, you can very clearly see curtains of rain falling from the clouds, and after a while, the clouds disappear. However, the rain comes down in torrents at the exact spot where the seeding took place, while other regions—deprived of the rain clouds—get absolutely nothing. It remains bone-dry, and everything withers away. When I contact the insurance companies—which, among others, commission these operations—the only answer I get is that it is about damage mitigation and that the situation isn't quite as I describe it. Has anyone else made similar observations? And what is the general opinion on the use of these planes? Am I looking at this too narrowly? Regards to all.

Seit langem verfolge ich den Einsatz der sogenannten Hagelflieger zur vermeintlichen Schadensbegrenzung. Grundsätzlich habe ich durchaus Verständnis für einen Einsatz, sofern dieser nachweislich erfolg hat. Allerdigs, und das ist meine Überzeugung, greift deren Einsatz massiv in das Wettergeschehen ein. So beobachte ich seit Jahren, dass die Region, in der wir leben, massi unter einem Rückgang des regens leidet. Für mich nachweislich deshalb, weil hier mindestens 3, meist sogar 4 und mehr der Flieger im Einsatz sind. Je nach angeblich drohender Hagellage. Ich will kurz die Funktionsweise erklären, wie es mir als Laie möglich und bekannt ist. Das Flugzeug hat an Außenstationen Brenner mit Silberjodid hängen. Es fliegt in die Nähe der Zellen und zündet dann die Brenner. Man erhofft sivch durch die freigesetzten Silberjodidpartikel als Kristallisationskerne eine deutlich frühere Abregnung bzw. wesentlich kleiner Hagelkörner, die zu Boden fallen. Man kann dann wirklich sehr, sehr deutlich aus der Ferne Regenschleier aus den Wolken fallen sehen und nach einiger zeit sind die Wolken dann auch verschwunden. Aber, der regen kommt sintflutartig an genau der geimpften Stellen herunter und andere Regionen, in Ermangelung der Regenwolken, bekommen absolut nichts. Es bleibt knochentrocken und es verdorrt alles. Von den Versicherern, die u.a. den Einsatz beauftragen, bekomme ich nur die Antwort: Schadensbegrenzung und so wie ich es darstelle ist es nicht wirklich. Hat jemand ähnliche / gleiche Beobachtungen gemacht? Und wie ist grundsätzlich die Meinung zum Einsatz der Flieger? Sehe ich das zu engstirnig? Grüße an alle P.S.: die Übersetzung kam von google Überetzer

    Excellent example :) Out of curiosity, where in Greece are you based? Have you noticed this pattern changing in recent years, or has it stayed fairly consistent? And what about the total accumulated precipitation, does it seem to be increasing, decreasing, or shifting seasonally? BR from meteoblue!

    Hello, and thank you for your question. The cloud cover percentage shown in the left column of the Stueve diagram represents total cloud cover, divided into low, mid, and high cloud layers, and does not specifically isolate convective clouds. Convective clouds are treated as a separate variable in meteoblue data and are not included in the total cloud cover percentage. However, the Stueve diagram does include convective parameters such as convective updraft in the point+ subscription. Additionally, convective cloud base, top, and vertical extent are available separately in meteoblue forecasts and APIs. We hope we were able to answer your questions and wish you pleasant weather with meteoblue.

    @WCT Thanks for sharing this report. Storms like Kalboishakhi can indeed develop and intensify very quickly, which makes them difficult to forecast in detail. But nowcasting tools such as radar help a lot. It is also fortunate that no tornadoes were reported. Have you observed any tornadoes or other particularly unusual storm features in your area recently?
