Four experiments were conducted in Hawaii in summer 1985, one primarily by NCAR scientists (William Cooper and Darrel Baumgardner of RAF and James Dye of the Convective Storms Division) and the others by university scientists (David Johnson of the Illinois State Water Survey, Kenneth Beard of the University of Washington, Tsutomu Takahashi of the University of Hawaii, and Marcia Baker of the University of Washington).

The early findings have shown several interesting results: coalescence processes appeared to act much faster than anticipated on the basis of theoretical calculations; raindrops were much larger than expected; entrainment analyses have illustrated differences between these and continental clouds; CCN measurements yielded concentrations that were highly variable; and the band clouds had an unexpectedly strong three-dimensional structure.
