    Opis:
    A three-dimensional hydrodynamic model was used to determine 12 zones of upand downwelling in the southern part of the Baltic Sea.O n the basis of a seven-year numerical simulation, the annual frequency of up- and downwelling events in various regions was analysed, their vertical velocity evaluated and the probability of their occurrence for different wind directions calculated.V erification of the model results demonstrated their good correspondence with satellite images, on average equal to 92%.The poorest consistency was recorded for upwelling in the Bornholm region (81%).The annual average frequency of strong upwelling (velocities > 10−4 m s−1) ranged from c.5–7% off the eastern coasts of the southern Baltic to > 31% along the north-eastern coast of Bornholm.A long the Polish coast (excepting the Vistula Spit) downwelling was recorded more frequently than upwelling.The frequency of strong vertical currents was highest in the area to the north of the Hel Peninsula, where high percentages of strong upwelling (27.1%) and downwelling (37.1%) were recorded.

    Opis:
    Madden-Julian oscillation (MJO) is an atmospheric oscillation due to atmospheric phenomenon that occurs due to the uniformity of solar energy received at the surface of the earth, MJO is a natural occurrence in the seaatmosphere system. When the MJO is active, in general there will be a disturbance in the upper air which is then followed by an anomaly at sea surface pressure causing the changes in the wind on the surface. The changes in the surface wind affect the sea surface currents which then cause the occurrence of coastal upwelling downwelling. The upwelling process itself is a process whereby a sea mass is pushed upward along the continent, when the beach is to the left of the wind direction, the ecological transport leads to the mass of water away from the coast. As a result, there is a mass vacuum (divergence) in the coastal area. This mass void will be filled by the mass of water from the inner layer that moves to the surface. Indonesian territory itself is passed by MJO in phases 3, 4 and 5, while for Sumatra region is passed by MJO phase 3 and 4. This research aims to identify the propagation of coastal upwelling during MJO on the west coast of Sumatera, therefore the data of geopotential height, surface pressure sea ( MSLP), zonal and meridional components and sea surface temperature are used to analyze how the MJO effect on the coastal upwelling occurs in the research area. The analysis was conducted in June, July and August by comparing the atmospheric conditions at the time of strong MJO in phases 3 and 4 with normal viewing of anomaly geopotential height and MSLP and then seeing the anomaly surface wind changes from zonal wind (u) and meridional wind (v) and changes in SST in Sumatra region. The result shows that there is a change of GH and MSLP when MJO passes the west coast of Sumatra and then follows the change in the value of u and v and SST to identify the upwelling, while the anomaly change negative SST does not occur when MJO is active but has time lag (lag). In this analysis it was found that SST anomaly occurs when the anomaly changes in both the upper and surface water occurring after 5 days in phases 3, 4 and 5.
