Abstract : Numerical model simulations, chamber tests, and field experiments are the three scientific approaches used to investigate the modification of warm fog and stratus. This study is an in-depth review of the literature on warm fog dissipation; both theoretical and experimental projects are reviewed and critical comments are made on the reported claims. Most all the projects on warm fog modification are summarized in various tables while a few are analyzed in a more detailed fashion. Special emphasis is put on the sponsoring agencies; the goals, objectives, and the amounts allocated by the various research sponsoring organizations are also reviewed. The need for greater statistical analysis in evaluating the results of field experiments is noted. Among the numerous techniques used to improve visibility, two are proposed as the most promising: the thermal dissipation of warm fog and stratus, and the combination of the seeding and helicopter techniques.
