Weather modification net

A weather modification network (or weather control system) was a system used to alter the natural weather patterns of a planet, acting much like a world wide environmental system.

In 2369, a weather control net was in place on Earth that was designed to dissipate destructive weather phenomena such as tornadoes. Malfunctions were rare, such as the one created by the Q in order to execute the parents of Amanda Rogers, who had deserted the Q Continuum to live among Humans but subsequently violated their promise not to exercise their powers. (TNG: "True Q")

Caldos had its weather modification net installed in the mid-23rd century, when Caldos colony was established there. The net was maintained from a substation located within the colony. The net experienced several malfunctions in 2370 due to interference from the anaphasic lifeform Ronin. Ronin was using the net as a way to maintain molecular cohesion during the transition from his previous host, Felisa Howard, to his next host, Beverly Crusher. The net required a power transfer from the USS Enterprise-D and the Enterprise-D environmental controls were later affected by feedback from the transfer. (TNG: "Sub Rosa")

A weather control network was installed on Hekaras II in 2370, to counteract the effects of instability in the Hekaras Corridor caused by warp travel. (TNG: "Force of Nature")

One of the most sophisticated weather control systems known was in place on Risa since at least the 22nd century, where it suppressed the naturally rain-soaked and dismal climate in favor of a sunny, tropical one. The system was sabotaged by the New Essentialists in 2373, with help from Lieutenant Commander Worf. Their actions were designed to make a point to the people of the Federation that the trivial pursuit of pleasure, such as on Risa, was weakening their moral fiber in the face of enemies such as the Dominion. (TNG: "The Mind's Eye"; DS9: "Let He Who Is Without Sin...")

The person in charge of the weather modification network on Risa was later determined to be working for the Orion Syndicate. (DS9: "Honor Among Thieves")
