There are several factors that affect salinity. Some of the main factors include evaporation and precipitation which will affect the salinity of oceans and seas.
Three factors are evaporation and freezing of sea water.
Temperature, salinity, and density are factors that form thermohaline circulation, which drives the global ocean currents. Temperature affects the water's density, with colder water being denser. Salinity also plays a role, with higher salinity making water more dense. Together, these factors influence the movement of water around the world's oceans.

evaporation
In open ocean evaporation affects the salinity of the oceans, in closed oceans the lack of sunrays cause greater salinity levels.

Density is affected by both temperature and salinity. The colder the temperature and the saltier the substance, the greater the density.
it makes cold water rise 2 the surface.and that's how sailinity affects currents.
