In The United Arab Emirates

[StOrM18]

National Centre of Meteorology and Seismology, the planes carried out nearly 18 sorties for cloud seeding since the beginning of the year until the end of last week, pointing out that the best time for the cloud seeding is the period of the summer months often.

</span>On the future plans in the field of seeding, Center said that although the UAE is one of the first countries in the Arabian Gulf has using a technique for cloud seeding, however, the draft seeding is still in its infancy and needs further studies and research, and that the Centre continues to this research to reach </span>the best results.

The Centre carries out from time to time new techniques in the process of pollination, where one of the two Committees of the center, walked to the tops of cloud above freezing (-5) at an altitude of 18 thousand feet, and then spray powder iodide silver to work on a crystal ice in nature </span>and attract water vapor molecules and condensed to ice crystals, begins to melt when it came down to turn into water before it reaches the ground, while the other aircraft aerial spraying cloud materials saline and various other installation from the bottom, and these materials have a physical property of a different effect in the compilation of water droplets, </span>and increased rainfall.

He pointed out that vaccination does not routinely conduct, because it depends on the presence of cumulus clouds viable vaccination at all, and often these clouds over the mountain ranges of the East at various times, restricted to between the hours of noon and before sunset in the summer, and are carried out cloud seeding </span>on different areas is not confined in a place designated by the State during the winter, depending on the situation affecting the air. And no failure rate in the process of cloud seeding, as the center is Bastmtar clouds viable to conduct such operations, which are usually quality wet already, while not working on making rain, but stimulate the clouds to generate as much as possible from rain water.

</span>And on how the entire process of seeding is simple, he said the Centre was working in the morning to study the weather conditions expected, the study of the opportunity to form clouds in a time and place, which usually begin in the afternoon in mountainous regions of East, to develop a readiness for aircraft that start with </span>control the airspace of the State via satellite and radar developed, and then when observing the start are clouds, and asked the pilots flying over the place of clouds, which are controlled aircraft by radar center, is guidance to the exact location of the clouds to start the process of pollination.

</span>He added: The pollination of the processes that require precision, which is to steer the plane to the right place of the clouds, as mentioned, at the right time are being formed, to ensure the desired goal of these operations, and are scattering materials pollination in the right place, and start then the salts in attracting and pooling </span>water vapor to tiny droplets of water, as a result of the clash of these droplets and docking with each other and become large and remain able to carry the air to drop from the clouds, and reach the ground as rain.

</span>The Center said that the process of burning torches take between 2-3 minutes per Calten, depending the number of burners used on the physical nature of the clouds the target, while ensuring the continuity of the air rising into the clouds, to be lifted material to the top of the clouds, and usually grow cloud after the scattered materials vaccination within a period not </span>exceed 20 minutes, depending on the number of burners used for the nature of the cloud and the large target.

On the side effects of cloud seeding on the environment, confirmed that the salt used in the process of seeding do not have any damage to the environment, and public health at all, which is a potassium chloride, sodium chloride, which exist in abundance in the atmosphere when compared to the amount added, and </span>the process of cloud seeding plays a key role to intervene in the structure of the physical clouds only, and there is no interference in the nature of the climate of a particular area, the goal of the process of seeding is to stimulate rain clouds to generate as much as possible from the falling water at the earliest, before the end of the age of the cloud, which </span>usually within the hour time ago.

He also stressed that these materials do not have any direct impact or indirect contamination of rain or air pollution, as the additives do not exceed 0,05 mg per liter, with the allowable percentage of the world is 50 micrograms per liter, as several countries have </span>long experience in such operations, including more than 50 years, a survey and study of water, and found that the amount added is negligible at

ummmmmmm

what you are think about that ??

I'm in my point of view as a wonderful, despite its high cost.

But are negative for other areas away from the area to vaccinate the cloud 60 kilometers, where the rainfall will reach the cloud weak to those areas. Will turn a light cloud to cloud density (high-altitude clouds.

I Hope hear from the experts in this forum.
