Geographical location

Geographical location of Rasht metropolis

Rasht was originally a bastion located between the two rivers Goharrood and Sayahrood, and has a long history. But in terms of urban history, the first time Hamda … Mostofi mentioned it in the eighth century AH. The old name for Rasht was Daralmorz or Daralaman, which was referred to as Bihar before the two.

In the dictionaries, the river or estuary has been designated between the two rivers, and it seems that the reason for its naming is to be located between the two rivers, which were considered as shields and walls of the city. Rashti’s facade in desatir culture means gypsum to solidify the foundations, stones and bricks, and in the dictionaries of Ara, Anandraj, Fars Asadi, Shoushtari local vocabulary, Argument, Nazim al-Ataba and Jahangiri vocabulary: something that Collapse; everything that collapses and collapses; the wall facing down. The plaster is also said to make the house white; the sludge; the soils; the soils;

Dehkhoda believes that since the city of Rasht was built in the year AH, so the name of this place has been used as a matter of history and the word Rasht is in the name of Abjad.

The development of the city of Rasht started from the time of Shah Abbas Safavi, who was then a Qusayr, and during the Qajar period, due to the economic development of Iran and Russia, the old name of the localities of the city of Rasht, which mostly reflects the occupation of its inhabitants. , Are also included in travelogues, with the exception of two or three of which are known and known by their old names, most of which are:

Sagharisazan; Roadbartan; Zahedan Kheyran; Daghaghian; Kozhran; Chehelan Khomehan; Chahar Khaneh; The city of Rasht is considered. This ancient texture, while being a part of the cultural heritage and reminiscent of the relics, traditions and traditions of ancient times, can be one of the significant problems in the urban context of this city. Rasht, known as the city of silver rains. It is the capital of Guilan province, and for the first time its name is mentioned in the book about al-Alam, written in the year AH, with a large area.
Rasht became the capital of Guilan Province and the center of the Noghan and Silk Transactions of Shah Abbas from 6 AH at the time, the first product of Gilan. This led to the great owners and Iranian, Russian, Greek, and Armenian merchants who were silk merchants of Silk, and the city of Rasht grew dramatically.

Murgunov, a Russian tourist who had traveled to Rasht in the year 6 AH, wrote in his memoirs that the city had two houses, a shop, and two people at that time. In his view, Rasht was a city well endowed with beautiful seaside homes where traders from India, Bukhara, Rome and the Ottomans traveled in silk soda. Guilan became one of the focal points of Iran’s political, social and economic developments during the constitutional period and afterwards. The independence movement of the jungle, the expansion of cities, the establishment of numerous schools and the promotion of the culture of the citizens of Rasht made it one of the most progressive cities in the country.

Climate Elements

Humidity

Rain

Another climate element that makes Guilan prominent among other provinces is the relative humidity. Relative humidity is generally the highest in the early hours of the morning and the lowest in the middle of the day, as it is calculated based on the ability of the air to hold moisture at different temperatures. Colder air can potentially hold less moisture and warmer air is more likely to hold moisture. For example, even if the absolute humidity in the air does not change in the morning and at noon, because the temperature is low in the morning and at noon, the ratio of absolute humidity to low and high temperatures will vary at different times. Day and night, it increases its proportion in cold weather and reduces it in hot weather. However, although relative humidity is generally high in the morning, and low in the afternoon, it is still harder to tolerate midday in the warm seasons of the year because of the humidity. It is higher, so that the 30-year average of the two times of day and night, 6:30 and 9:30 pm, shows that the center of Gilan (Rasht) with 94 and 72% relative humidity, respectively The aforementioned hours are among the hottest cities in the provincial capitals. After Rasht, Ardabil has the highest humidity with 89% in early morning and Gorgan with 58% in Nimroz.

Humidity does not pose a problem for human comfort in conditions where the ambient temperature is not high, such as in the morning in Guilan, but high relative humidity if accompanied by high ambient temperature, It takes comfort from humans, and what climatologists call climate disruption. In fact, when the ambient temperature is high and relative humidity is high, body transpiration will not evaporate, or at least not evaporate properly. In other words, due to the high relative humidity, the evaporation does not evaporate to cool the body. In fact, the body’s immune system’s response to heat-induced transpiration is due to high air humidity, which prevents evaporation, resulting in the body’s ability to cool. This state of affairs, known as arid climatology, disrupts the human organism for routine, routine activity. The climate or climate of Gilan province among the provinces of the country has, in several respects, prominent features; Gilan’s climate is more rainy than anywhere else in Iran. For example, the city of Rasht, the geographical center of the province and the representative of the Gilan plain, is the most productive part of the country – with the exception of points in Gilan itself. The average annual rainfall of 30 years from 1345 to 1374 is estimated at 1401 mm. Among the provincial capitals of the country, except for Sari by the Caspian Sea, only Yasuj is located 831 mm after Rasht, which is somewhat close to it (National Statistical Yearbook: 2003). The other cities of the province namely Anzali, Astara and Lahijan had precipitation of 1554 mm (average rainfall of 53 years between 1330 to 2004) and 1379 mm (mean rainfall of years 1340 to 2004) (Guilan province statistical yearbook: 1383).

Topography

Study of climatic conditions of Guilan province

Guilan highlands can be divided into two main groups:
The first group is a part of the Alborz Mountains that separates this region from the central plateau of Iran by south of Gilan province. Rasht city in the north of this part of the highlands of the province is low.
The second group, located along the Talesh city, separates Gilan from Azerbaijan. The cities in these areas are generally mountainous, with only a narrow strip of land adjacent to the sea. The northern part of the city of Rasht is located at a lower elevation than the high seas and some parts of it are swampy and swampy. Generally, moving north to south of Guilan province, sea level rises, eventually blocking the southern highlands through the massive Alborz Mountains.
