Study the size and type of condensation nuclei of rain drop over Baghdad city in (2018)

Abstract

The current study has been carried out to know the size and type of Condensation nuclei that are responsible for the clouds droplets and that being considered one of the main factors to grow such droplets through using samples of rain drops for Feb and April months. To examine these samples, it has been used two types of devices which are ( eds and esm) of high accuracy to know dimensions and components of these nuclei. The current study has indicated that there is a set of the chemical elements of high effectiveness on quantity of saturated water vaporization and represented in the following elements ( Na, Ci, Si, Mg,C) depended on its Molecular weight. Max molecular weight has been recorded in the 1st sample and that was for Na, which is 5,63mg and the minimum weight that has been recorded was 0.82 mg, also chlorine CI recorded Max molecular weight 8.46mg and Min molecular weight was 0.3mg. These two elements compose salt and this kind of salt plays a huge role in composing droplets since it is considered soft and there are elements recorded max ratios of molecular weight including silicate Si ( 28,04)mg and is of a huge effect upon saturated vapour pressure and also there are other elements that could be of effectiveness upon vapour pressure like Carbone C recorded 50.88mg.
