Atmospheric transport processes

• The weather conditions associated with precipitation in 2017 have been analyzed and 36 periods of several days, which are typical of different seasons and parts of the country, have been separated;


• A joint analysis of the physico-chemical parameters of the precipitation and atmospheric circulation at the three stations for 23 periods from 2017 was made. The influence of the Northwest transmission in cases of lower acidity on Cherni Vrah and Sofia, as well as the influence of the transfer from Sahara in July;


• An analysis was carried out for the separation of dry periods with breeze circulation in Ahtopol;


• A comparative analysis was made for the chemical composition of rainfall and cloud water samples of Cherni Vrah.
