Synoptic weather-typing, or the classification of weather conditions into categories, is a useful tool for climate impact applications. Numerous procedures have been developed to accomplish this goal. Before the advent of high-speed computers, manual methods were most common; more recently, more automated methods have come into wide use. Both types of classification have shortcomings; manual me...
according to cheng (1999), in recent esl/efl literature, asian (especially east asian) learners of english as a foreign/second language have been arguably reported as reticent and passive learners. the most common allegations are that these students are reluctant to participate in classroom discourse; they are unwilling to give responses; they do not ask questions; and they are passive and over...
After the establishment of the first quarantine station in the Republic of Ragusa (modern-day Dubrovnik) in 1377, the states and principalities of Italy developed a sophisticated system of defensive quarantine in an attempt to protect themselves from the ravages of plague. Using largely unknown and unseen historical maps, this paper reconstructs the extent and operation of the system used. It i...
abstract in this study, trends of threshold heavy precipitation were examined on the basis of measurements of 1437 stations (included synoptic, climatic and rain gage stations) in iran for the period of 40 years (1964-2003). for this purpose, the statistical method of nonparametric mann-kendall test is used for analyzinging the thresholds of heavy precipitation and nonparametric sen method for ...

For a synoptic analysis of high polluted days in 13 and 14 November 2007, a combinatorial synoptic analysis was used. From methodology prospect, the present study has utilized the "circular environment" synoptic approach and with respect to the restrictions on very high-polluted days in Mashhad city, the subjective synoptic analysis used for data processing and analyzing the prevailin...
Climate change is a phenomenon that has affected natural ecosystems and all aspects of human life in recent years. Therefore, identifying and predicting climate change can greatly help manage it and reduce its harmful effects. The purpose of the present study is to identify whether or not occurrence of climate change by extreme indices including TXx and TNn during 1961-2015. In addition, CanESM...
the study of spatial and temporal changes in climate parameters, is one the most important issues in the world's climate research. study of changes in cloud cover as one of the most important climate parameters is important, because clouds are in top of hydrologic cycle and changes in them make changes in spatial and temporal variations in other climate parameters. in this study, the spati...
