the occurrence of dust storms and their sources in the southern and central parts of iran during the period of 2002 to 2009 was investigated. for this purpose, the meteorological and synoptic data, data from the middle and upper atmosphere, and wind flow tracking model were used. dust storms and nddi were traced using satellite imagery from fasa, shiraz, and bushehr stations. analysis of the gr...

Climatic parameters in time and space scales of change are for many reasons of Changes and how they should be based on observations using a statistical method to be determined. Analysis of the most widely used statistical methods that assess potential climate change on hydrological time series, such series of precipitation, temperature and flow rate used. This study of 11 synoptic,rain gage and...

introduction thunderstorms of the most important, most abundant of the most severe weather hazard that each year, in addition to large quantities of crops and infrastructure development, causing human casualties are also around the globe. between 1953 and 1957 the financial losses caused by the hurricanes in america has over 3.6 million dollars (changnon;2003,1231).storms of varying intensities...

First, it cannot explain the differences among the writers—unless it is assumed that verbal differences indicate different events. In that case, one would have to say that Jesus was tempted by the devil twice, that the Lord’s Supper was offered twice, and that Peter denied the Lord six to nine times! In fact, one might have to say that Christ was raised from the dead more than once if this were...

The present study attempts to introduce a method of statistical downscaling with a synoptic view. The precipitation data of Golestan Province has been used for the years 1971 to 2010. Employing multivariable regression, this study models the precipitation gauges in the station scale, by making use of 26 predicting components of model HadCM3, on the basis of two A2 and B2 scenarios. However, the...
