Dr. Mehdi Rahnama in a conversation with Mehr reporter about the origin of microbes in pollution Rece citiesDiffere Iran said: Depending on the geographical area where dust has happened, the source of microbes varies. In some areas of the coury of dust origin Iernal Is and some pois of their origin Foreign Is. For example These days the source of the major part of dust in the southwest and west of the coury Foreign It is from Iraq, Saudi Arabia, Kuwait and so on to Iran.
He coinued: The origin of the dust phenomenon in Tehran in rece days Based on Modeling and monitoring performed at the Meteorological Research and Joe Sciences Research Iernal It has been. The dust has moved to Tehran from Tehran, Alborz, parts of Markazi province, Qazvin province and Qom.
According to the head of the Institute of Meteorological and Barley Sciences, the south -east dust of the coury is mainly originated Foreign He has moved from the border with Afghanistan and Pakistan this dust and with dust published of the origin of the origin Iernal Is iensified. Especially in Sistan and Baluchistan and Kerman province, the sequence of dust phenomenon with origins Iernal And Foreign This exacerbation Phenomenon It becomes.
He Remember Kurdish: In the northeast of the coury, a combination of dust with origin Iernal (In Khorasan Razavi Province) and Origin Foreign (From Turkmenistan) We have activated at the same time and created dusty air in these areas.
Dust with origin Iernal Is rising
Referring to the role of Salehieh wetland in Tehran dust, Rahnama said: Models We have been shown as a part that exacerbates Tehran’s dust, and this wetland has been active in increasing the conceration of dust in rece days.
The head of the Meteorological and Joe Science Institute in response to the question of whether the pattern of microbes has changed in rece years. He said: The modeling we have done at the research shows that still the source of much of the microprocessors in the coury Foreign And we are affected by dust in couries such as Syria, Iraq, Saudi Arabia, Kuwait, Afghanistan, Pakistan and Turkmenistan. But in rece years, due to the conditions of climate change and the consta droughts that the coury is involved in, resulting in the loss of natural vegetation, lack of rainfall, reduced soil moisture, and so on. Iernal Has increased.
Attacks Has the 6 -day war caused Tehran’s air pollution?
In response to the question of whether the Zionist regime attacks and the destruction of buildings, etc. can cause dust and air pollution in Tehran? He said: We do not confirm this; Because the Zionist regime’s attacks were a poi, but dusty Now We are confroed with a wide range of Tehran province. These attacks occurred in Tehran, but they have exposed the dust from the west to east of Tehran province and have been involved in this problem to Semnan, Isfahan, Qom, etc.; That’s why We do not confirm this.
Rahnama added: In areas that are attacked, it may be regional, such as when construction operations are carried out, more than elsewhere; But to say that the attacks have exacerbated the dust. Most of the dust is a natural origin these days and due to climate change and the activation of poteial and actual focus Iernal And Foreign Is.
Should we get used to dust?
“I agree with this talk,” said the head of the Meteorological and Joe Sciences Institute of Meteorological and Joe’s Institute of Science in response to one official saying that “people should get used to dust”. We have to admit that our coury has been dry, desert and with minimal natural land coverage for ceuries. In the past in architecture and lifestyle in areas Differe The coury, like ceral and southern regions, considered climatic parameters and had resulted in phenomena such as land, dehydration and dust storms, which have not been addressed in rece years.
“So we have to admit that we live in a desert, dry, low rainfall and high temperatures and the possibility of atmospheric phenomena such as dust,” he said. We also have to admit that the impact of climate change in the Asian region, especially Southwest Asia and Iran, is very high, so that in addition to increasing the occurrence and severity of the phenomena, even our seasons have changed. For example The time of summer weather has reached about six mohs from two mohs. We experience a shorter spring season, which will definitely have long -term effects. But I do not accept the part of putting hands and accepting the dust.
The researcher emphasized: Now We have methods of dealing with desertification, methods of consolidation of dust ceers, territorial planning methods as well as protected agriculture, etc., which can reduce the effects of climate change. If we have a territory plan for agriculture, agricultural land will not become dusty. If dusting ceers are stabilized at the right time, it will help reduce dust emissions.
Couries’s experiences Differe To manage dust
. According to the official; We need to have the methods of consolidation of the ceer, the methods of reducing natural effects on the prevalence of dust, and so on, and organizations such as the Natural Resources Organization in the Desert, the National Environme Agency, especially the Office of Climate Change, and the National Dust Staff, should be on the agenda.
Rahnama emphasized that one -dimensional solutions to reduce dust do not work, saying: Based on The models that are being done in the world, we need to consider an iegrated way. That is, at the same time as water resources manageme, natural resource manageme, rangeland manageme and iegrated territorial manageme, and communicate all the factors that coribute to the releva agencies in the form of a comprehensive program. This comprehensive manageme in China, the Arab couries, especially Saudi Arabia, as well as Spain, has done well, and if we move on to this poi we can solve this problem in a shorter and better effective time.
The problem of lack of iegrated meteorological data network in the coury
In response to the question of whether the infrastructure has been collected and the air quality measuring, especially the microbes in our coury, this is a good position in our coury. Said no; Unfortunately, we do not have a cohere iegrated network to collect ground data about the phenomenon of dust nationwide. Stations that Now Available, are not iegrated and part of it in the City Air Quality Corol Company Differe Located, some stations are related to the National Environmeal Protection Monitoring Network and part of the network is in the coury’s meteorological organization. But none of them are iegrated and their data is not shared.
He also said that because of the rules and restrictions, there is no iegrated system for sharing data, he said, “It also has many weaknesses and the network density is very low.” Usually the networks are in the metropolis, and some small cities that even have active dust ceers, especially the ceral parts of the coury, have no station or few stations.
He added: “In areas that need more monitoring, we also do not have a dense network and the data is not shared by public and we are in trouble in terms of monitoring and ground measureme and we are not in good shape.”
How is the origin of microbes ideified?
The researcher explained the methods of ideifying the origin of the microbes: Differe models and methods are used to ideify the origin of dust and all models are used in combination. We have produced several products at the Meteorological and Barley Science Research Institute with the combination of ground models and meteorological models that use satellite images and ground stations as well as native predicted models. From the combination of all of these models, we have produced a native model used in the research institute and is a combination of meteorological models, ground models, satellite images and other data.
He Remember Kurdish: For example, there is a data called “Earth’s Saved Perceage” that shows the perceage of paving a range and determines that there is a few perce of the stone within one meter in one square meter. This shows how much dust uprising is. Also, territorial erosability and data based on the amou of erosability of each poi Based on What a factor like wind.
“We combine all this data together with meteorological models, and we have finally created an iegrated model and we are producing the product of” predicting dust conceration “. Based on Also ideify that origin of dust.
“We said:” We said Now We have plans for artificial ielligence that will be unveiled in the near future.
