Heavy precipitation plays a significant role in arid and semi-arid regions of Iran. In order to understand the effect of blocking high system on rainfalls in northwest Iran during 25 - 28 October 2008, meteorological conditions including pressure, wind fields and temperature at multiple levels of the atmosphere were analyzed. Sea level pressure, the 1000-500 hPa thickness, perceptible water, re...
abstract venlafaxine, 1–[2–(dimethylamino)–1–(4–methoxyphenyl) ethyl]cyclohexanol hydrochloride is a novel non-tricyclic antidepressant. venlafaxine is a second generation antidepressant drug, has a neuropharmacologic profile distinct from that of existing antidepressants including tricyclic compounds, selective serotonin reuptake inhibitors and monoamine oxidase inhibitors. venlafaxine impart...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Synoptic analysis of the torrential on Day 21, 1398 (Case study: Zahedan and Qeshm) Abstract Rainfall is the most important phenomenon or feature of the environment and so far many studies have been done about its causes. In any place, rainfall occurs when humid air and climbing cause are provided. Both of these conditions are provided by the circulation pattern. The study area is affe...
This study uses a statistical downscaling method based on self-organizing maps (SOMs) to produce highresolution, downscaled precipitation estimates over the state of Pennsylvania in the mid-Atlantic region of the United States. The SOMs approach derives a transfer function between large-scale mean atmospheric states and local meteorological variables (daily point precipitation values) of intere...
We describe the first simulation experiment and output archives of the Project to Intercompare Regional Climate Simulations (PIRCS). Initial results from simulations of the summer 1988 drought over the central U.S. indicate that limited-area models forced by large-scale information at the lateral boundaries are able to reproduce bulk temporal and spatial characteristics of meteorological fields...
introduction drought is one of the climate risks that has made iran to be one of the 10 countries subject to drought. scientific knowledge about this phenomenon is necessary in order to plan, manage and confront with problems resulting from drought. considering the spatial extent and climate variability of iran, all climates of this country are prone to drought. due to the fact that khorasan ra...
The work examines the seasonality and large-scale atmospheric circulation patterns associated with debris-flow occurrence in the Trentino–Alto Adige region (eastern Italian Alps). Analysis is based on classification algorithms applied to a uniquely dense archive of debris flows and hourly rain gauge precipitation series covering the period 2000–2009. Results highlight the seasonal and synoptic ...
Introduction Geographical situation of Iran is a place for interacting many physical and human processes which lead to specific precipitation climatology in the country. The month to month variation of precipitation is one of the features which the precipitation climatology may reflect due to tempo - spatial characteristics. In fact, monthly distribution of precipitation is one of precipitati...
Climate change is nowadays a major cause of concern in water related fields because it may cause more severe, shortened or prolonged droughts or floods in the future. In this research was tried to the best model of climate change is determined from the climate change models to determining the minimum temperature, maximum temperature and precipitation for the Birjand synoptic station. For this r...
