Identification of Effective Synoptic Systems in Moderate and Severe Frosts Occurrence in Tehran

Mahdi Modiri; Zahra Alibakhshi; Faramarz Khoshakhlaq; Ali Hanafi

Volume 21, Issue 84 , February 2013, , Pages 7-20

  In order to recognize the effective synoptic system in creation of moderate and severe frosts in Tehran and the conditions under which sever and moderate storms transform into one another, synoptic analysis has been implemented by mean sea level 850 and 700 hp maps in a period of 45 years (1961-2005). ...  Read More

Zoning of Agricultural Climate of Strawberry Cultivation Using Geographic Information System (Case Study: Mazandaran Province)

Faramarz Khosh Akhlagh; Mohsen Soltani

Volume 20, Issue 78 , August 2011, , Pages 32-38

  One of the main pillars of agricultural planning is the identification of agricultural climatic units. An agricultural climatic unit is a unit in which the ground features and climatic elements are considered as integrated units, and each unit can have different characteristics. In this regard, the condition ...  Read More

Analysis and Forecasting of Meteorological Droughts of Khoy Synoptic Station

Faramarz Khosh Akhlagh; Ali Hanafi; Saeed Ahmadi

Volume 19, Issue 74 , August 2010, , Pages 24-29

  Drought is one of the most important natural hazards that works in a slow and creeping way. This phenomenon is due to climatic processes, and its severity and frequency depend to a certain extent on the geographical position of the site, which happens every few years as a result of falling precipitation. ...  Read More
