Introduction


The Blanket Effect is intended for others to learn about weather modification and its related subjects in an easy to understand way. Started in 2005, this blog is a work in progress as the technology advances

Clearing Roadway Fog With Nitrogen

STATEMENT AT THE ITALIAN SENATE HEARING ON WEATHER MODIFICATION
WMO’s ACTIVITIES ON WEATHER MODIFICATION—COOPERATION WITH ITALY

by Professor G.O.P. Obasi
Secretary-General
World Meteorological Organization

(Rome, Palazzo Giustiniani, 22 June 1999)

[An] example of direct Italian involvement in weather modification activities is that of the Italo-Slovenian Hail Prevention Project.

This had its origins in 1975 in agreements between Italy and Yugoslavia but, for some time now, Slovenia has taken on a coordinating role with Italy. (image left: location of Slovenia,

A research plan was drawn up in 1985 and it is my understanding that the project is still in the developmental stage or otherwise acquiring equipment and instrumentation needed for a modern hail prevention experiment.

A technology using liquid nitrogen developed in the Russian Federation has therefore been modified to suit local conditions and successfully implemented by TECNAGRO with international scientific advice.


Concerning ground traffic, the fog dispersal nitrogen technique has been used on the Venice–Trieste Motorway under various meteorological conditions at different sections of the motorway. (image right showing area of roadway, click for detail, from stv.ts.it)

During 1995–1998, experimental data were collected. Six stationary and a mobile liquefied nitrogen dispensers were used. The visibility increased considerably within 30–40 minutes after the use of liquid nitrogen.
