IRAN STATISTICAL YEARBOOK 1392 1. LAND AND CLIMATE

51

Introduction he statistical information appeared in this chapter includes the Geographical characteristics and administrative divisions, and Climate. 1. Geographical characteristics and administrative divisions Iran comprises a land area of over 1.6 million square kilometers. It lies down on the southern half of the northern temperate zone, between latitudes 25º 00' and 39º 47' north, and longitudes 44º 02' and 63º 20' east. The land’s average height is over 1200 meters. The lowest place, located in Chaleh-ye-Loot, is only 56 meters high, while the highest point, Damavand peak in Alborz Mountains, rises as high as 5610 meters. The land height at the southern coastal strip of the Caspian Sea is 28 meters lower than the open seas.Iran is bounded by Turkmenistan, Caspian Sea, Azerbaijan, and Armenia on the north, Afghanistan and Pakistan on the east, Oman Sea and Persian Gulf on the south, and Iraq and Turkey on the west Administratively, the country is divided into Ostans, Ostans into Shahrestans, and Shahrestans into cities and Dehestans.Highlands of Iran can be divided into four mountain ranges: northern, western, southern and central and eastern ranges. The northern mountain ranges have extended from Ararat Mountain in Turkey to Hindu Kush Mountain in Afghanistan, including Alamdar, Sahand, Sabalan, Talesh, Qaflan Kuh mountains in Azarbayejan, Albourz mountain ranges at the north of Tehran and south of Mazandaran and

Gilan Ostans, Ala Dagh, Binalud, Hezar Masjed and Qarah Dagh in Khorasan Ostanon the east of Iran.The mountain ranges in the west, which have extended from Ararat Mountain to the north west and the south east of the country, cover Sari Dash, Chehel Cheshmeh, Panjeh Ali, Alvand, Bakhtiyari mountains, Pish Kuh, Posht Kuh, Oshtoran Kuh and Zard Kuh and form Zagros ranges .The highest peak of this range is “Dena” with a 4409 m height. .Southern mountain range stretches from Khouzestan province to Sistan & Baluchestan province and joins Soleyman Mountains in Pakistan. The mountain range includes Sepidar, Meymand, Bashagard and Bam Posht mountains. Central and eastern mountains mainly comprise Karkas, Shir Kuh, Kuh Banan, Jebal Barez, Hezar,Bazman and Taftan mountains, the highest of which is Hezar mountain with a 4465 m height.The largest Iranian islands that are mainly located at Persian Gulf and Hormuz Strait, are Qeshm, Kish, Lavan, Larak Shahri, Hormuz, Hengam Jadid (new Hengam), Kabudan, Ashk (Orumiyeh Lake), Faroor Bozorg (Great Faroor), Hendurabi, Khark, Minou,Siri, Khan, Abu Mosa, Espir (Orumiyeh Lake), Tonb Bozorg (Great Tonb), Morghi, Kharku, Arezoo, (Orumiyeh Lake), Faroor Kuchak( Small Faroor) and Tunb Kuchak ( Small Tonb). The Caspian Sea (the world’s largest lake) lies on the north of Iran and connects Iran to European countries through Russian waterways. The water of most of the Iranian lakes is salty.

The major internal lakes are: Orumiyeh, Namak, Hamoun Jazmourian,Hamoun-e-Saberi, Bakhtegan,Toshak, Hamoun-e-Pouzak, Maharlu, Hamoun-e-Hirmand, Talab-e-Anzali( Anzali lagoon), Howz-e-Sultan, Parishan and Zarivar of Marivan. 2. Climate Due to its vast area, abundant mountains, desert lands and being adjacent to two large seas at the north and south as well as its closeness to Europe, Mediterranean Sea, African large Sahara desert, Indian Ocean, Asian internal highlands and large cold areas, Iran enjoys a very diverse climate. The effect of distance from the sea, namely closeness and remoteness from sea, can be easily perceived by comparing the large amount of rainfall and rich vegetation and highly populated areas around the Caspian Sea with the uninhabited arid deserts in the centre of Iran. The continuation of the mountain ranges, their location opposite or parallel to the winds direction and air flows are among the factors, which always affect climate change. There is a significant difference among slopes facing or backing onto humid winds in terms of rainfall amount and vegetation. The country generally features three climatic zones:1. Arid and semi-arid climate of the interior and far south, characterized by long, warm and dry periods, lasting some years over 7 months. The annual precipitation in such regions varies between 30 to 250 mm. 2. Mountainous climate, which are sub-divided into cold and moderate mountainous climate. 2.1. Cold mountainous climate: about 40000 sq km of the total country consists of major highlands, including Alborz and Zagross

mountain ranges, as well as Sahand and Sabalan high peaks. The annual precipitation in these regions exceeds 500 mm. 2. 2. Moderate mountainous climate:some 300000 sq km of the country enjoys moderate mountainous climate, where the annual precipitation varies from 250 to 600 mm. 3.Caspian climate, which is a narrow strip with a limited extension, trapped between the Caspian Sea and Alborz mountains range with as much as 600 to 2000 mm precipitation per annum. Measurement of climatic characteristics, which dates back to the year 1320, is currently performed by the National Meteorological Organization at its numerous synoptic stations scattered around the country. The data in this chapter, however, are only from those located in Ostan (provincial) centers. They include temperature, precipitation, and relative humidity, the number of frosty days, hours of bright sunshine and speed of wind.

Notes:1. Some capitals of Ostans have several synoptic stations and the data appeared here are from those located at the airports of Ostan's capitals. 2. Central basins, Hamun and Sarakhs, were renamed Central Plateau, Eastern Border, and Qareh Qum, respectively in the year 1383. The Statistics in this Chapter have been gathered from Armed Forces Geographical Organization, Ministry of Interior, I.R. of Iran Meteorological Organization and Iran Water Resource Management Company.

Definitions and concepts Shahrestan (subprovince):an administrative division with a certain geographical boundary,


53

formed from joining of a few neighboring Bakhshes(county) which enjoy homogeneous natural, social, economic, political and cultural conditions.Bakhsh (county): an administrative division with a specific geographical boundary, including a number of neighboring Dehestans and their adjacent fields, places, Roostas (hamlets), and possibly Shahrs, which are similar in natural, social, cultural, economic and political aspects. Shahr (city .town):an area with a legal boundary, located within the geographical boundary of a certain Bakhsh and in terms of constructional context, employment and other factors, having the distinctive features of a city. Dehestan (rural agglomeration): the smallest unit among administrative divisions with a specific geographical boundary, comprised of a number of neighboring Roostas and their adjacent places and fields, homogeneous in environment, economic and social conditions that allow for providing public services and planning within a single system and network. Synoptic stations (simultaneous meteorological reporting stations): These are stations at which, various climatic features including dry and humid temperatures, amount and type of cloud, amount of precipitation, type of climatic phenomenon, direction and speed of wind, amount of evaporation, air pressure, hours of bright sunshine, changes in pressure, amount of solar radiation, etc. are according to certain instructions at certain hours measured and communicated to meteorological centers across the globe by devices like SSB, telephone or telex after being registered.Absolute minimum: the lowest temperature during a certain period (24 hours, one month, one year, or a few years).

Absolute maximum: the highest temperature during a certain period (24 hours, one month, one year, or a few years). Relative humidity: the amount of humid air in a volume unit of air. Average height of precipitation: is the weighted mean of an area. By dividing the area into several polygons and considering the precipitation in each polygon, the average height of precipitation is calculated.Water basin: is a geographical area in which overland flows from, and drains downhill into a body of water, such as ocean, sea, or flat. If the concentration point is located inside the basin, the basin is a closed one (e.g. Orumiyeh Lake), but if the point is located at the end of the basin, so that the flow can leave there, then there is an open basin. Every given point in a river is considered the concentration point for the basin just above it. Aquatic year: from the first day of Mehr to the end of Shahrivar of the next year.Coefficient of overland flow: the ratio of the volume of water flowed in a given hydrometric station to the volume of the precipitation of the basin stretching to the station.Hydrometric stations: stations in which parameters of debit (discharge), sediment, temperature, physical properties of water and features of ice cover and chemical properties of rivers, lake and dams reservoir are observed and measured. Volume of overland flow: To estimate the volume of overland flow of each of the country’s main basins, a total of 42 rivers have been selected to indicate and represent the overland flow whose annual total volume exceeds 60 percent of the country’s grand total. To reach the volume of any individual flow, a proper


54

coefficient is applied to the total volume. Selected information

The total length of the I.R. Iran’s borderlines is 8574 kilometers out of which the longest borderline is for that of south waters with 2040 kilometers and the shortest one goes to Iran-Armenia which equals 45 kilometers. In the year 1391, Sistan & Baluchestan, Kerman, South Khorasan, Fars, Khorasan-e-Razavi and Esfahan were among the largest provinces in the country respectively, and each of them has an area of more than 100000 Km2. Tehran province with an area of about 14000 Km2 ranks 29th among the nation’s provinces. In the year 1391, I.R.Iran was divided into 31 Ostans (provinces), 422 Shahrestans (sub-provinces), 1041 Bakhshes (counties), 1224 Shahrs (cities) and 2566 Dehestans (rural agglomerations). In 1392 average maximum and minimum temperatures in Ostans’ centers belong to Bandar Abbas with 26.5O C and Ardebil with 9.3O C respectively. Furthermore, the absolute maximum belongs to Ahvaz with 50.4O C and the absolute minimum goes to Shahr-e-Kord with -28.6O C. Also in the said year, the highest annual precipitation of the country belongs to Rasht and Sari, which amounted to 1325 and 741 mm respectively, and Semnan and Yazd with 80 and 64 mm respectively had the lowest annual precipitation amongst all Ostans’ centers. In the year 1392, the maximum frosty days belong to Shahr-e-Kord with 137 days,Yasuj with 117 days and Hamedan with 114 days; and Ahvaz, Bandar Abbas and Bushehr have not experienced any frosty day.The volume of precipitation in national main basins during the aquatic year of 1391-92 was approximately 393.276 bln m3 out of which the

share of each basin is as follows: the Caspian Sea 70.789 bln m3, the Persian Gulf and Oman Sea 148.588 bln m3, the Lake of Orumiyeh 17.105 bln m3 , Central Plateau 136.064 bln m3,Eastern Border 11.58 bln m3& Qareh Qum 9.15 bln m3.It is also noteworthy that the ratio of the area of main water basins to the total country area is as follows: the Caspian Sea 11.00%, the Persian Gulf and Oman Sea 26.00%, Lake of Orumiyeh 3.00%, Central Plateau 51.00%, Eastern Border 6.00 % and Qareh Qum 3.00%.
