"Cylinders"?????

WTH are you talking about? (Search actually turned up your post -- but, not much else!)

Thanks!

As best I can determine, the only "cylinders" proposed or actually dropped within hurricanes were/are Radiosondes".

Radiosondes" are, essentially, cylindrical "instrument packages" which measure -- and report back via radio -- hurricane parameters such as temperature and pressure.

The (passive) Radiosondes" have no measurable effect on the physical or thermodynamic aspects of a hurricane.
