- Аннотация: Dependence of precipitation daily sum, acidity and ion composition from atmospheric circulation is studied on the base of backward air mass trajectories for 1982-1993. Main parameters of trajectories are estimated, they are shown to have noticeable difference for summer and winter. In regular grid cells frequency of trajectories is calculated for every precipitation case in the center of European Russia depending on the daily precipitation sum, acidity and SO42-/Cl- relationship. It is shown that the highest frequency of trajectories for heavy precipitation both in winter and summer takes place within the same regions. For weak precipitation a seasonal difference exists. It is obtained that when air comes from Scandinavia and north of European Russia precipitation mainly has pH>5, and when it moves from Central and South Europe it is pH<5 in most cases. Cl- ions prevail for trajectories following from central Mediterranean and Central Asia as well as, in lower degree, from Scandinavia and Russian northern seas.
