Hurricanes, Convective Clouds, Precipitation 

 Processes 



The weather modification research program 

 conducted by NOAA is aimed primarily at devel- 

 oping a sound, scientific basis for practical weath- 

 er modification through theoretical studies, labora- 

 tory investigations, computer modeling of severe 

 storms and convective cloud processes, and con- 

 firmation by experimental field projects. The ef- 

 fort concentrated on: (I) Mitigation of damage 

 caused by hurricanes and severe convective 

 storms including extratropical cyclonic systems; 

 (2) the modification of convective clouds in a sub- 

 tropical environment (Florida) to increase rainfall; 

 and (3) research on the physics and chemistry of 

 cloud and precipitation processes.

Thermospheric Studies 



Studies of the neutral composition, ion compo- 

 sition, and temperature of the thermosphere have 

 been carried out by the NOAA Aeronomy Labo- 

 ratory using ground-based airglow observations 

 (Refs. 2, 3). Solar occultation by the earth as seen 

 from a satellite (Ref. 4) and theoretical chemical 

 analysis (Ref, 1) have been carried out since 1968, 

 and the satellite and airglow studies are continu- 

 ing.

Other Projects 



In addition to the most significant projects list- 

 ed previously, NOAA has conducted research in 

 other areas during the past 10 years which, al- 

 though highly cited, has not evidenced a coherent 

 history of citations. These papers, published since
