An ocean general circulation model (oGCM) was used in concert with a global database of inert gas measurements (Ne, Ar, N2/Ar and Kr/Ar) to constrain the magnitude of bubble mediated air-sea gas flux. We illustrate the inverse method using a simple bubble model that includes two end member types of bubbles: small bubbles that completely dissolve, and larger bubbles that briefly are submerged an...
In recent years, the severe fluctuations in precipitation have affected various parts of the country. On the southern coasts of the Caspian Sea, precipitation as one of the important climatic parameters has undergone changes due to global climate change. In the present study, we tried to evaluate the effect of climate change on rainfall in this region by applying a suitable model. In this study...
[1] The stability of the glacial thermohaline circulation (THC) with respect to North Atlantic freshwater input is examined using a global ocean general circulation model. It is found that the quasi-equilibrium hysteresis behaviour is much less pronounced under glacial conditions than under present-day conditions, and the existence of multiple equilibria requires an anomalous freshwater inflow....
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
In order to conduct faithful simulations of ocean circulation one needs considerable computational power and storage capabilities. We study the parallelization of a three-dimensional ocean circulation model (OCM) and provide summary results from recent experiments on the Cedar hierarchical architecture. A major goal of our effort is to obtain guidelines for the proper design of OCM codes for pa...
