The “Montserrat-2000” severe flash flood event which occurred over Catalonia on 9 and 10 June 2000 is analyzed. Strong precipitation was generated by a mesoscale convective system associated with the development of a cyclone. The location of heavy precipitation depends on the position of the cyclone, which, in turn, is found to be very sensitive to various model characteristics and initial cond...

By means of two stratifications of experimental days of the Whitetop Project-into categories E and W and into categories air mass and frontal-the effects of cloud seeding on precipitation downwind, upwind, and to the sides, up to 180 miles from the seeding line, were investigated. No significant effects were found for W and frontal days. On the other hand, for E and airmass days, significant an...

decreasing changes of climatic elements such as: daily precipitation, weekly precipitation, seasonal precipitation and annual precipitation can be toward to drought phenomena. the recognition it and planning for passing it, could be decreasing of disasters, because create of drought is slow but it effects is very damages. the aim of this paper is descriptive analyze and it type of research is a...

Understanding dominant processes influencing microorganism responses to storm events aids in the development of effective management controls on pathogen contamination in surface water so that they are suitable for water supply, recreation, and aquatic habitat. Despite the urgent needs at present, numerous facets of microbial transport and fate are still poorly understood. Using correlation and...

Background & Aims of the Study: Due to widespread dust-storms in the western regions of Iran and the significant role of meteorological parameters in formation and control of these storms, this study aimed to explore the correlation between meteorological parameters and dust-storm occurrences in the western part of Iran. Materials & Methods: In this cross-sectional study, meteorological param...

abstract aims: regular physical activity can reduce the burden of chronic diseases, such as heart disease, diabetes, and some cancers, and can prevent early death. this study examined the impact of performing health promotion model intervention on physical activity of the health volunteers. materials & methods: this cross-sectional research is part of a three-month intervening study started in ...

This study evaluates the temporal variability of the Antarctic surface mass balance, approximated as precipitation minus evaporation (P 2 E), and Southern Ocean precipitation in five global reanalyses during 1989–2009. The datasets consist of the NCEP/U.S. Department of Energy (DOE) Atmospheric Model Intercomparison Project 2 reanalysis (NCEP-2), the Japan Meteorological Agency (JMA) 25-year Re...
