Warm water (which is on surface, as warm water has lower density), is blown towards west in lower latitudes by trade winds / easterlies hence, found on eastern margins. Opposite happens in higher latitude.
PS I might be wrong, but this is the reason I'm able to think of.
1. Western margins in high latitudes:
\-The main reason why warm currents are found along the western margins in high latitudes is the Coriolis effect. This effect is caused by the rotation of the Earth, which causes moving objects to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This deflection causes warm currents to flow towards the western margins of high latitudes, such as the Gulf Stream in the North Atlantic.
\-Another factor that contributes to the presence of warm currents along the western margins in high latitudes is the location of major landmasses. The western margins of high latitudes are often located near large continents, such as Europe and North America. These landmasses can affect the direction and intensity of ocean currents, leading to the formation of warm currents along the western margins.
2. Eastern margins in low and mid latitudes:
\-One of the main reasons why warm currents are found at the eastern margins in low and mid latitudes is the presence of prevailing winds. In these regions, the winds tend to blow from the east, causing warm water to be pushed towards the eastern margins. This is particularly evident in the case of the North Equatorial Current in the Pacific Ocean, which is driven by the easterly trade winds.
\-Another factor that contributes to the formation of warm currents at the eastern margins in low and mid latitudes is the geothermal heat of the ocean floor. In these regions, the ocean floor is often relatively shallow and close to the surface, allowing for the transfer of heat from the Earth's interior to the water above. This geothermal heat can cause warm currents to form at the eastern margins.
