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 Mountain Fog in Uzbekistan

(note: We present another possible use for weather modification from an excerpt of a presentation originally from the 9th World Meteorological Organization Scientific Conference on Weather Modification in Antalya, Turkey, 22- 24 October 2007)

Activities on weather modification in Uzbekistan started in 1963.

Based on the weather conditions of the region and [the] system of the national economy management in the region, the main development of the activities directed at the weather modification was aimed at the hail-protection operations and activities on the atmospheric precipitation enhancement.

The results of these activities were presented almost at all [of the] international conferences on weather modification and cloud physics since the first one, which was held in 1973 in Tashkent.

During the past years we have studied the problems of [the] possibility, need and expediency of the cloud and fog dissipation, [the] precipitation of the cloud moisture on the mountain slopes, [using] measures against frost, prevention (warning) of avalanching, land-slides, floods, [and] mudflows.

These studies [have] shown, in particular, that cloud seeding is of interest mostly in certain situations when it is necessary to clear the sky over the astronomical observing point, during the public festivals and possibly, for agriculture.

The latter needs further revision concerning the assessment of the expediency of carrying out these activities.

Cloud dissipation above the airports in the foothills and plain regions was not rational taking into account the overcrowding of their space with a great number of aircrafts; the matter of the need in the fog (clouds) dissipation over the mountain motor roads being in the single transport system was not raised.

After achieving the independence by the states of the Central Asian region, the united transport system was broken, and re-evaluation of the values of production in separate regions of the country had taken place.

The traffic links began to be restored between the neighboring states along the Silk road. In these conditions the necessity arose in the increase of the capacity of highway of motor roads with taking the rough orography into account.

One of the handicaps in these conditions is closing the motor roads or reducing the traffic capacity of the motor roads in relation to the decrease of visibility in these fog (clouds) conditions.

We think that for Uzbekistan it is required to study the relevent areas in such regions as Kamchik mountain pass on the motor road section of Angren-Kamchik mountain pass-Pap Takhtakirachi mountain pass on the section of Samarkand-Kitab motor road, the road junction of in the area of the Jizak mountain pass and on the motor road on the section of Dekhan-Sherabad in the area of the spurs of Baisuntau mountain range.

These are the sections of the motor roads in mountain regions which connect separate territories of Uzbekistan which do not have alternative ones.
