atmospheric circulation patterns are responsible for drought and flood occurrences around the globe specifically in moderate mid latitude climates. while some circulation patterns are responsible for wet spells and floods as well, the drought events can be attributed to some other circulation patterns. therefore, identification and distinction of dry/wet producing patterns and the geographical ...
abstract in recent years, dust storm in western part of iran, especially fars province, caused various problems for people. the aim of this research is the identification of circulation patterns producing dust storms over fars province. for this purpose, firstly the code number 6 of current weather at 12 gmt belongs to 8 synoptic stations during the statistical period of 1992-2003 has been extr...
â â â this paper attempts to investigate the relationship between 500hpa circulation patterns and weather types (coldest, warmest and raining) over 16 synoptic stations of mountainous region of iran. the mountainous region of iran covers about 670000 square kilometer (41 percent) of iran. in this paper have been investigated the relationship between circulation patterns in 500hpa level with we...
weather circulation patterns play a main role in the occurrence of environmental phenomena especially in middle latitude. occurrence of dry and wet spells is in relation to synoptical system repetitions and types of weather. in this research first by using of standard precipitation index (spi), extensive droughts in the province were identified. then by using principal component analysis (pca) ...

Introduction: Data mining is a process for discovering meaningful relationships and patterns from data. Identify behavior patterns of libraries users can helps improve decision-making in libraries. This study aimed to analyze the interlibrary loan transactions in Birjand University of Medical Sciences using data mining algorithms. Methods: In this descriptive study, knowledge discovery and d...
The Persian Gulf is an important region in the world regarding energy supply, transportation, shipping, and military missions. Therefore, studying the annual circulation of water current in the Persian Gulf is very important for marine experts. In the present study, the simulation of current circulation in the Persian Gulf has been studied using ROMS numerical model and field observations. The ...
We can identify the flood not only considering circulation pattern in occurring day but also by studying circulation pattern a few days before fresh event. This subject has mutual approach. In one hand, it indicates that circulation patterns which were before flood event have important role in determining the conditions and moisture content of studied area and playing the fundamental role...
Observations of the Caspian Sea during August-September 1995 are used to develop a three-dimensional numerical model to be used in calculating temperature and current. The model has variable grid resolution and horizontal smoothing that filters out small scale vertical motion. Data from the meteorological buoy network on the Caspian Sea are combined with routine observations at first-order syno...
