Synoptic variability of low-cloud properties, temperature advection, and thermodynamic soundings of the trade wind boundary layer are analyzed, using the long data record from ocean weather station November (308N, 1408W). The variations in low-cloud amount at this subtropical site are most strongly correlated with variations in temperature advection, the stability of the lower troposphere, and ...

Tujuan Screening criteria adalah untuk mengetahui kecocokan surfaktan NaLS ampas tebu sebagai fluida injeksi terhadap sampel minyak intermediate. Metode yang digunakan pada screening ini uji laboratorium meliputi aqueous stability, perubahan fasa, emulsi, tegangan antar muka (IFT) dan kestabilan thermal. Hasil intermediate crude oil menyatakan bahwa tidak menggumpal tetap jernih, sehingga memen...

purpose estimating wind chill index as one of the indexes effective in body comfort, specifically for athletes and tourists interested in winter sports. methods meteorology data including temperature and the percentage of relative humidity of 6 synoptic stations of chaharmahal-bakhtiyrai province, iran from 1990 to 2007 were extracted from iranian meteorology site. in order to calculate the val...

Abstract The potential evapotranspiration is considered as an important element of the hydrological cycle, which plays role in agricultural studies, management plans irrigation and drainage networks, hydraulic structures. Estimating reference particular climatic regions at different time scales, one most atmospheric parameters, a importance optimal use resources. series analysis method, GARCH m...

the main objective of this paper is to study climate changes and fluctuations in the four synoptic stations in sistan and baluchistan province in the past few years and to analyze statistically and simulate and forecast for the next years (2040-2009). this study used data from the outputs of general circulation climate model echo-g with a1 scenario that are now used at the university of hamburg...

background:osteoporosis is one of the most common metabolic bone diseases. the purpose of this study is to investigate the effect of a walking education program based on the health belief model (hbm) on osteoporosis among women.   methods and material in this quasi-experimental research design, 120 patients (60 experimental and 60 control),who were registered with the health centers in fasa cit...

through this article, the distribution of air pollutants in tehran have been simulated based on wind patterns with and without the presence of synoptic by tapm (a meso-scale model). the simulation covers three horizontal resolution domains 30, 15 and 5 kilometers. the pollutants chosen for this are co and pm10 and wind data is 10 meter height level. the result has shown that the model simulated...

because of the passing of the air systems, temperature changes are often very sudden and plants cannot adapt themselves to these fluctuations and get damage. because low temperatures have harmful effects on the agricultural productions, so, the investigation of these temperatures are very useful for predicting and preventing probable damages. in this study, for determining the time of the freez...
