A single parameter representation of hygroscopic growth and cloud condensation nucleus activity
We present a method to describe the relationship between particle dry diameter and cloud condensation nuclei (CCN) activity using a single hygroscopicity parameter κ . Values of the hygroscopicity parameter are between 0.5 and 1.4 for highly-CCN-active salts such as sodium chloride, between 0.01 and 0.5 for slightly to very hygroscopic organic species, and 0 for nonhygroscopic components. Obser...
متن کاملA single parameter representation of hygroscopic growth and cloud condensation nucleus activity – Part 2: Including solubility
The ability of a particle to serve as a cloud condensation nucleus in the atmosphere is determined by its size, hygroscopicity and its solubility in water. Usually size and hygroscopicity alone are sufficient to predict CCN activity. Single parameter representations for hygroscopicity have been shown to successfully model complex, multicomponent particles types. Under the assumption of either c...
متن کاملInteractive comment on “A single parameter representation of hygroscopic growth and cloud condensation nucleus activity – Part 2: Including solubility” by M. D. Petters and S. M. Kreidenweis
We thank Ari Laaksonen and the two anonymous reviewers of this manuscript for their comments. In the following we provide individual replies to each review. Reviewer 1 This manuscript provides an extension of the kappa formalism introduced by the same authors in ACP in 2007 (PK07) to account for compounds with limited solubility. An algorithm to calculate critical supersaturations is provided. ...

این پایان نامه به بررسی و مقایسه دو موضوع مطابقه میان فعل و فاعل (از نظر شخص و مشار) و هسته عبارت در دو زبان انگلیسی و آذربایجانی می پردازد. اول رابطه دستوری مطابقه مورد بررسی قرار می گیرد. مطابقه به این معناست که فعل مفرد به همراه فاعل مفرد و فعل جمع به همراه فاعل جمع می آید. در انگلیسی تمام افعال، بجز فعل بودن (to be) از نظر شمار با فاعلشان فقط در سوم شخص مفرد و در زمان حال مطابقت نشان میدهند...
