Hi Alan--In that the term "climate" includes all of the moments of the
system, so including extreme weather, etc., if an approach were
developed that was used consistently to affect on a persistent basis one
characteristic/moment of the system that is usually talked about as a
weather event, would that not be geoengineering? That is, is
geoengineering just a change in the long-term average or might the term
also apply to modification of a particular moment of the system? For
example, would it be geoengineering if one were able to modify the Asian
monsoon on a consistent basis?

Of course, in spite of their title, this is not geoengineering. It is
weather modification.

Abstract
The concept of seeding giant-sized ocean salt water aerosols in the
eye-wall of a cyclonic storm abruptly increasing cloud condensation
nuclei (CCN) concentration is investigated. To bring this to effect,
design of a novel injection mechanism – a modified naval artillery
shell, tailor made for the Indian Navy fleet, containing sea-salt
solution to disperse the CCN is proposed. The effect of the seeding
is modeled using a robust optimized warm rain microphysical
scheme – amenable for quick local forecasts within the Weather
Research and Forecast framework. The combined protocol results in a
significant decrease in precipitation tendencies upon landfall.
