The estimation of the two most intensive climatic factors impacting on phytoplankton communities was carried out for marginal seas of western Pacific. Influences of some tropical cyclones on chlorophyll "A" concentrations (obtained by SeaWiFS) in 2001 were considered. It is shown that tropical cyclones cause local algae blooming at some regions. Also influence of dust storms from Gobi desert on phytoplankton at the area of the Sea of Japan was analyzed for the spring of 2006. Vladivostok lidar station data and MODIS data were applied for the analysis. Ground lidar data have shown that the most aerosol mass was in lower atmosphere layer (0-3 km). So dust storm could influence on the element composition of surface seawater layer. The high correlation coefficient between time series of chlorophyll A concentration and of aerosol optical thickness (at the 869 nm) was detected.
