The influence of clouds on the large-scale atmospheric circulation is examined in numerical simulations from an atmospheric general circulation model run with and without atmospheric cloud radiative effects (ACRE). In the extratropics of both hemispheres, the primary impacts of ACRE on the circulation include 1) increases in the meridional temperature gradient and decreases in static stability ...

weather condition is one of the much effective factors in the principle of architecture and urbanization. so in this research long-term trend of effective climate elements in architecture of darab city including mean of minimum temperature, temperature mean, mean of maximum temperature, minimum relative humidity, maximum relative humidity, relative humidity mean, wind speed and sun hours in mon...

Abstract A simple air–sea coupled model for wind–evaporation–sea surface temperature (SST), wind-induced turbulence–mixed layer (ML)–SST, and wind–evaporation–ML–SST feedback is extended to unitedly represent the precipitation anomaly associated with moisture convergence ML depth (MLD) due freshwater-induced buoyancy flux. An eigenanalysis reveals presence of yet another accompanying a cross-eq...

Determination of river runoff is essential in design and construction of most hydraulic structures including dams. In rivers with no measurement stations, the hydraulic models can be used for data estimation.  SWAT is one of the most widely-used numerical models. In this model, input influential meteorological data as precipitation, temperature, wind speed, solar radiation and relative humidity...

Using a high-resolution regional climate model RegCM3, station and satellite observations, we have studied the spatial heterogeneity of climate variability over Java Island, Indonesia. Besides the well-known anomalous dry conditions that characterize the dry and transition seasons during an El Niño year, analysis of regional model output reveals a wet mountainous south versus dry northern plain...

The 1998 annual cycle and 1991–98 summer simulations of Greenland ice sheet surface climate are made with the 0.58-horizontal resolution HIRHAM regional climate model of the Arctic. The model output is compared with meteorological and energy balance observations from 15 Greenland Climate Network automatic weather stations. The model reproduces the monthly average surface climate parameters, to ...

climate change is a phenomenon that has made the most concern in communities and decision making centers. this phenomenon has important effects on different aspects of human life. one of the most important crops that are affected by climate change is wheat. accordingly, data and information of northern khorasan have been used to study the effects of climate change on rain-fed wheat yield. for t...
