Je mogoče spreminjati vreme?

Dež je mogoče priklicati s posutjem določenih kemikalij oziroma s cloud seedingom.. Kitajci imajo to zadevo v malem prstu. ;)

Teorije zarote kot so HAARP pa pustmo pri miru... Ni dobro za zdravje človeka..

Ce zelis spreminjati vreme, moras na nek nacin dodati ali odvzeti sistemu energijo. Energije v vremenskih pojavih so enormne v primerjavi s "cloveskimi" energijami.

Primer cez palec: (s Wind power) @ Wikipedia Moc, ki jo lahko dobis iz vetra je reda velikosti 1MW/km^2. Obrnjeno: zato, da na samo kvadratnem kilometru povrsine ustvaris "uporaben" veter, rabis 1MW energije, ki jo moras od nekje dobiti. Ce hoces to podrocje razsiriti na 20x20km, ze rabis celotno moc, ki jo proizvede NEK v Krskem... Da stevila vetrnic za to sploh ne omenjam. In seveda dajstva, da se pogovarjamo o hitrostih vetra okoli 50km/h.

Drug primer: (s Thunderstorm @ Wikipedia Ce bi hotel "ustvariti" eno samo tipicno nevihto, bi rabil toliko energije, kot jo je bilo sproscene pri eksploziji atomske bombe nad Hirosimo, 10^15J. Ce bi hotel to nevihto ustvariti v doglednem casu, recimo v eni uri, bi rabil 277TW moc. To je ekvivalentno okoli 400 NEKov, ki bi obratovali na polni moci.

Iz tega je pomoje precej jasno, da z resno kontrolo vremena se dolgo ne bo nic.

1.
China by far has the largest investment in both operational programs and weather modification research programs. Every province except one has an active weather modification program in China.
2.
After China the USA, Thailand and India have the largest investment in operational weather modification programs. There are currently active operational weather modification programs in at least nine states located in the western United States with often times multiple cloud seeding projects in the individual states (California, Nevada,Utah, Idaho, Wyoming, Colorado, North Dakota, Kansas and Texas). While funding for weather modification has increased over the past five years in the USA it is still well below the levels in the 1980's. India is currently one of the largest investors in weather modification research with a major multi-year program conducted by the Indian Institute of Tropical Meteorology in Pune, India. Thailand is also embarking on a major researcheffort in this area.
3.
There are now several operational programs around the world that have conducted cloud seeding annually for more than 50 years without interruption. In the USA and Australia these programs are mostly supported by hydro-electric power companies.
4.
Two major research programs in weather modification to enhance snowpack are currently ongoing in the U.S. namely in Wyoming (Including modeling and field work in part funded by the National Science Foundation) and Idaho (modeling funded by Idaho Power). A smaller research project has been started in the State of Texas.

Conclusion
1)
Weather Modification has been conducted in Indonesia since 1983 to overcome water shortage. Weather modification activities were mostly to fill up dams for hydro electric power plant, irrigation and fresh water. Sometimes, weather modification was also carried out to extinguish field/forest fires and clear up smoke during dry season.
2)
Weather modification in Indonesia is now playing an important role as tool for national water resources management.
3)
Development of weather modification technology is urgently required. The WMTC - BPPT Indonesia needs to collaborate with both International institutions and inter - agencies in order to successfully improve the cloud seeding technique and research in Indonesia.
