“…A brief evaluation of the PLASIM model is conducted, in order to show that the PLASIM model is capable of reproducing the key features of the South and East Asian monsoons to a sufficient degree of accuracy for our purposes. Similar versions of the PLASIM model have been shown to perform well in climate simulations [72,73]. Figures 1-4 show the performance of a 50-year control simulation with the PLASIM model for key variables of surface temperature, relative humidity, circulation and precipitation.…”

“…It includes parameterisation schemes for land-surface interactions, radiation and convection. There are several versions of the PLASIM model, where adaptions have been made to allow inclusion of additional climatic components such as vegetation, sea ice and ocean [72,73]. We use the version developed by [74], which features a large-scale geostrophic ocean component.…”

The South and East Asian summer monsoons are globally significant meteorological features, creating a strongly seasonal pattern of precipitation. The stability of such a strongly seasonal hydrological cycle is of extreme importance for a vast range of ecosystems and for the livelihoods of a large share of the world's population. Simulations are performed with an intermediate complexity climate model, PLASIM, to assess the future response of the monsoons to changing concentrations of aerosols and greenhouse gases. The aerosol loading consists of a mid-tropospheric warming and a surface cooling, which is applied to India, Southeast Asia and East China, both concurrently and independently. The primary effect of increased aerosol loading is a decrease in summer precipitation in the vicinity of the applied forcing, although the regional response varies significantly. The decrease in precipitation is only partially ascribable to a decrease in the precipitable water, and instead derives from a reduction of the precipitation efficiency, due to changes in the stratification of the atmosphere. When the aerosol loading is added in all regions simultaneously, precipitation in East China is most strongly affected, with a quite distinct transition to a low precipitation regime as the radiative forcing increases beyond 60 W/m2. The response is less abrupt as we move westward, with precipitation in South India being least affected. This lower sensitivity in South India is attributed to aerosol forcing over East China. Additionally, the effect on precipitation is approximately linear with the forcing. The impact of doubling carbon dioxide levels is to increase precipitation over the regions and weaken the circulation. When the carbon dioxide and aerosol forcings are applied at the same time, the carbon dioxide forcing partially offsets the surface cooling and reduction in precipitation associated with the aerosol response.

Numerical modeling is one of the leading research tools for the climate problems. Among numerical models, researchers use, in particular, coupled models, that are numerical models describing more than one climate component dynamics and their interactions. The simulation results with such models depend on the way how these interactions are configured. Therefore, a proper configuration of the exchanges is crucial. The software called a "coupler" is often used to configure these interactions. The coupler is most helpful if the model components are independent of each other modules, their number exceeds two, and they have their own computational grid and time integration step. Key functions of the coupler are managing data exchange between models, setting up synchronous interaction between them based on the time integration step, and interpolating data from one model's computational grid to the other model's grid. Additional functions can also be implemented, e.g., fluxes computation between model components, data assimilation, working with the file system, etc. The coupler has one crucial feature: if there is a set of different models of climate system components, one can construct new coupled models by coupling various subsets of these components with coupler. This paper gives an overview of the SCM (SibCIOM Coupling Module) coupler we first developed for the model SibCIOM (Siberian Coupled Ice and Ocean Model). The description of this coupler has not been published before. The SCM coupler is a separate module to which the main climate system model component, such as atmospheric, oceanic, sea ice and land components, can be attached. Additional functions of this coupler include computation of atmosphere-to-ocean and atmosphere-to-ice fluxes and ocean and sea ice state correction using a tidal model. This paper also gives examples of two models constructed with the SCM coupler.
