Regional climate models (RCMs) are considered to be more useful than general circulation models for assessing impacts of climate change scenarios in agriculture. In this communication, the climatic outputs of an RCM–PRECIS (providing regional climates for impact studies) model were analysed by comparing its baseline simulation daily weather data on temperature and precipitation patterns with th...
Heavy PM 2.5 (particulate matter with an aerodynamics diameter less than ?m) pollution frequently happens in Wuhan under unfavorable meteorological conditions. To comprehensively understand the complex impact of both regional-scale synoptic forcing and local-scale processes within planetary boundary layer (PBL) on air quality Wuhan, this study analyzed long-term concentration measurement, near-...
Abstract Persistent dry winter events over the eastern Mediterranean (EM) disrupt rainy (winter) season precipitation patterns and dramatically reduce water availability in region. Here we objectively identify persistent dry, warm Israel, apply a Lagrangian approach to three case‐studies, aiming understand relation between synoptic setting, precursor Rossby waves, how conditions emerge. Self‐or...
در این پایان نامه در ابتدا دلایل شکل گیری آلاینده ها در شرایط cold start و warm up و راهکارهای کاهش آنها ارائه می شود. در ادامه، بهینه سازی فرایند شکل گیری مخلوط هوا و سوخت از طریق کنترل دقیق نسبت هوا به سوخت بعنوان یکی از بهترین راهکارهای عملی کاهش آلاینده ها در شرایط cold start و warm up با جزئیات کامل مورد بررسی قرار می گیرد. مدل بدست آمده (برای موتور پیکان انژکتور)، شبیه سازی می شود و نتایج...
The effect of weather on social interactions has been explored through the analysis of a large mobile phone use dataset. Time spent on phone calls, numbers of connected social ties, and tie strength were used as proxies for social interactions; while weather conditions were characterized in terms of temperature, relative humidity, air pressure, and wind speed. Our results are based on the analy...
Additives are chemical compounds that added to concrete during its manufacture modify one or more of properties. The first additive used in modern was the accelerator, intended shorten time which material is not capable supporting stress. Traditionally, accelerators have been made from calcium chloride, but today trend use chloride-free additives prevent reinforcing steel corroding and thereby ...

This study documents the characteristics of the large-scale structures and diabatic heating and drying profiles observed during the Tropical Warm Pool–International Cloud Experiment (TWP-ICE), which was conducted in January–February 2006 in Darwin during the northern Australian monsoon season. The examined profiles exhibit significant variations between four distinct synoptic regimes that were ...
