Until recently, high-resolution global modeling of tides has been done separately from the atmospherically-forced oceanic general circulation. Here we review emerging class models that are simultaneously forced by both atmospheric fields and astronomical tidal potential. Such simulate barotropic (surface) tides, internal near-inertial motions, eddying circulation, a partially resolved gravity w...

The response of the monsoonal and annual-meanHadley circulation to orbital precession is examined in an idealized atmospheric general circulation model with a simplified representation of land surface processes in subtropical latitudes. When perihelion occurs in the summer of a hemisphere with a subtropical continent, changes in the top-of-atmosphere energy balance, together with a poleward shi...

The regional climate response to radiative forcing is largely controlled by changes in the atmospheric circulation. It has also been suggested that global climate sensitivity depends on the circulation response, an effect we call the “atmospheric dynamics feedback”. Using a technique to isolate the effect of changes in atmospheric circulation on top-of-atmosphere (TOA) radiation, we calculate t...

An important step toward improving radiative transfer codes in general circulation models (GCMs) is to thoroughly evaluate them either by comparison to measurements directly or by comparing them to other data-validated radiation models. The Rapid Radiative Transfer Model (RRTM) shortwave (SW) radiation model accurately reproduces direct beam fluxes from the Line-by-Line Radiative Transfer Model...

Anthropogenic aerosols are a major factor contributing to human-induced climate change, particularly over the densely populated Asian monsoon region. Understanding the physical processes controlling the aerosol-induced changes in monsoon rainfall is essential for reducing the uncertainties in the future projections of the hydrological cycle. Here we use multiple coupled and atmospheric general ...

Diagnostics of atmospheric momentum and energy transport are needed to investigate the origin of circulation biases in climate models and to understand the atmospheric response to natural and anthropogenic forcing. Model biases in atmospheric dynamics are one of the factors that increase uncertainty in projections of regional climate, precipitation and extreme events. Here we define requirement...

A new type of ultra-high resolution atmospheric global circulation model is developed. The new model is designed to perform ‘‘cloud resolving simulations’’ by directly calculating deep convection and meso-scale circulations, which play key roles not only in the tropical circulations but in the global circulations of the atmosphere. Since cores of deep convection have a few km in horizontal size...

This present research work was carried out to evaluate the energy consumption in a typical Iranian building based on the forecast of climatic variables. Thus, the LARS-WG model was validated for some northwest stations of Iran, including Tabriz, Ardebil, Oromieh, Kermanshah, Hamedan, Sannandaj, Qazvin, and Zanjan. The average monthly outdoor temperature was forecasted from 2011 to 2100. The rel...
