From the "Coast to Coast AM" website:

Weather Manipulation
Television weatherman Scott Stevens shared his view that Project HAARP or similar technology has been used to manipulate the weather by altering atmospheric waves, and that this has been going on for decades. He came to this conclusion after studying visible satellite imagery showing large weather systems with anomalous "punched out" sections and square clouds. The punched out energy from these systems are moved to other parts of the sky, he explained.

The technology, Stevens suggested, was probably based on the ideas of Tesla, but utimately it has been adapted to create floods, heat waves, and other weather disturbances for military or profit purposes. Though he has not seen the actual equipment or blueprints he believes that Russia, Japan, America, Brazil, Israel and possibly India and China all have this weather manipulation technology.

Such technology, Stevens said, could also be deployed for positive uses, such as a counter measure to prevent hurricanes. He also commented that the chemtrail phenomenon is real and that the planes involved are making the trails in order to mark off energy signature areas.

A caller to the program, Doug from San Francisco, said he was a former librarian for the Defense Department and claimed that HAARP used ELF to decimate crops in North Korea.
