"Understanding physical and chemical processes that guide the formation and evolution\r\nof giant molecular clouds (GMCs) has important implications for the formation of stars.\r\nGMCs dominantly consist of molecular hydrogen, but there are more than 200 chemical\r\nspecies of various combinations of carbon, nitrogen and oxygen atoms. Together, these\r\nspecies control the cooling ability with the thermal and dynamical evolution of the\r\ngas cloud. In order to overcome the restrictions encountered by most previous models\r\nof molecular cloud formation due to the complexity of chemical reaction networks\r\nand its inclusion in hydrodynamical codes, we have implemented detailed treatment\r\nof atomic/molecular cooling and hydrogen chemistry into state-of-art high resolution\r\nhydrodynamical simulations. The main focus of our study is on the influence that\r\nchoosing between different cooling functions and turbulent driving has on the formation\r\nand evolution of molecular gas. In that manner, we study the influence of the nature of\r\nthe turbulence on the formation of molecular hydrogen by examining both solenoidal\r\n(divergence-free) and compressive (curl-free) turbulent driving. The obtained results\r\nwe use to test a simple prescription suggested by Gnedin et al. (2009) for modelling\r\nthe influence of unresolved density fluctuations on the H2 formation rate in largescale\r\nsimulations of the ISM. We also investigate the properties of the dense clumps\r\nformed within our model of the molecular cloud formation in converging flows and\r\ndirectly compare the results obtained using the simple, parametrized cooling function\r\nintroduced by Koyama & Inutsuka (2002) and used by a number of converging flows\r\nstudies with the results of the detailed calculation of the non-equilibrium chemistry\r\nand thermal balance of the gas. Finally, we study C I and CO emission from molecular\r\nclouds in comparison to their column densities and the total column density, as we\r\nlook for the way to trace the structure of the cloud."^^ .
