Winds, land masses and Coriolis effect are major factors in the generation and path of ocean currents.
Convection cells are due to temperature differences.

Winds, land masses, and the Coriolis effect are factors that affect both convection cells and ocean currents.
To understand how these factors influence convection cells, let's start with the concept of convection. Convection is the transfer of heat through the movement of a fluid, such as air or water. In Earth's atmosphere, convection is driven by the uneven heating of the surface by the Sun. When the air near the surface is heated, it becomes less dense and rises, creating a convection cell.
The first factor, winds, play a crucial role in convection cells. Air movements known as wind are driven by the unequal heating of Earth's surface, which creates areas of high and low pressure. The differences in atmospheric pressure cause the air to move from areas of high pressure to low pressure, which in turn affects the formation and direction of convection cells.
The second factor, land masses, can significantly influence convection cells. Land masses, such as mountains or large landforms, disrupt the flow of air, causing it to be redirected or blocked. As air encounters a mountain, it is forced to rise, condense, and precipitate on the windward side, creating a rain shadow effect. This alteration in air movement can impact the formation and distribution of convection cells.
The Coriolis effect is the third factor that influences convection cells. The Coriolis effect is a result of Earth's rotation and causes freely moving objects, such as air molecules, to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This deflection contributes to the rotation of convection cells, affecting their size, shape, and direction of movement.
In the context of ocean currents, these same factors - winds, land masses, and the Coriolis effect - also have a profound impact. Winds blowing across the surface of the ocean create friction, which sets the water in motion. As the wind patterns change, ocean currents respond accordingly.
Land masses can act as barriers to ocean currents, causing them to be deflected or redirected. These land masses can include large continents or islands. For example, the Atlantic Ocean's Gulf Stream is deflected eastward by the presence of continents along its path.
The Coriolis effect also plays a significant role in influencing the direction of ocean currents. As with atmospheric circulation, the Coriolis effect deflects ocean currents to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
Therefore, winds, land masses, and the Coriolis effect collectively impact both convection cells in the atmosphere and ocean currents in the ocean. Understanding these factors helps explain the complex patterns and movements of air and water on Earth.
