This is the first modeling reconstruction of the whole aspects (both meteorological and oceanographic) of the storm which hit Italy on 4 November 1966, producing 118 victims and widespread damages in Tuscany, at the northern Adriatic coast and in the north-eastern Italian Alps. The storm was produced by a cyclone which formed in the western Mediterranean and moved eastward towards Italy, reachi...
Soil temperature is one of the important variables in hydrology, agriculture, meteorology and climatology studies. Owing to the fact that soil temperature is only measured at synoptic stations, reconstruction of this variable in other places is of great importance for many relevant agricultural surveys. Using 10-year (1996-2005) daily meteorological observations, including: air temperature, glo...
PURPOSE The objective of this study was to evaluate the effect of meteorological factors on the onset of idiopathic sudden sensorineural hearing loss (ISSHL). MATERIALS AND METHODS Meteorological data from 2005 to 2011 were obtained from the web-based "Monthly Weather Reports of the Meteorological Administration" database. Patients with ISSHL who visited our hospital during this same period a...
Introduction: During the summer of 1976 Viking Lander 1 and 2 touched down at Chryse Planitia and Utopia Planitia, Mars respectively. The primary aim of both Viking Landers was to look for the presence of organic life on the surface of Mars, however each Lander also had a comprehensive meteorological package to monitor the martian atmospheric conditions [1]. The meteorological package consisted...
Abstract. One of the major problems in using wind energy is that wind-generated electricity is more unstable than electricity generated by other sources, and therefore integrating wind energy use with traditional power generation systems can be a challenge. This problem can be effectively reduced by having accurate information about the mean and wind speed volatilities. Therefore, in this paper...
Wind energy production is very sensitive to instantaneous wind speed fluctuations. Thus rapid variation of wind speed due to changes in the local meteorological conditions can lead to electrical power variations of the order of the nominal power output. In small grid as they exist on islands (French West Indies) such fluctuations can cause instabilities in case of intermediate power shortages. ...
in this paper, the 10-minutes period measured wind speed data at different heights (10 m, 30 m, and 40 m) are presented for khvaf, which is one of the major counties with high wind potential in khorasan provinces in iran. to the author’s knowledge, there hasn’t been any assessment works in the mentioned site. from the primary evaluation and by determining mean wind speed and also the weibull fu...
Problem: Droughts in Zabul have cause the erosion of human habitats, especially in areas exposed to sand accumulation. Creating an optimal urban form can be a way to counteract its destructive effects.Methodology: in this paper, the research method is based on the partial air flow simulation method and the city form survey. The goal is to find the most optimal form of residential buildings to r...
introductionin comparison with fossil fuels which pollute the lower layer of the atmosphere, use of windenergy has many environmental and economic advantages. wind is a clean and renewableenergy resource and use of the energy in the recent decades has been welcomed so much in theworld. energy plays an important role in the development of each society. all differentactivities including housing, ...
Wind measurement is important for estimating wind energy potential, but it is relatively cost-intensive and often conducted at a narrow height from the ground level. The typical range of most turbine hub heights is from 30-50 m or even higher. Extrapolation on wind data thus becomes necessary to estimate the wind speed at different heights. Doing so requires the essential understanding of wind ...
