factors influencing ocean current

1. Wind direction

Prime factor deciding the direction of wind current alongwith origin.

Eg. Somalian current towards Somalia during North West monsoon

2. Shape of the continent

Although it is not a causative agent but it influences the direction of ocean current

Eg. Brazillian landmass divide ocean current there into two parts.

3. Rotation of earth

Causes Coriolis force which bends ocean current

In northern hemisphere - clockwise

Southern - anti clockwise

4. Relative temperature

Also determines direction of ocean current as temperature determines density of the ocean water. Generally warm water moves towards cold waters

Ancient trade routes based on direction of ocean currents alongwith wind direction.

Multi dimensional impact of ocean current

Gulf stream (warm) moderates climate of Western Europe (UK)

otherwise UK would have been much colder according to its latitude

Mixture of cold ocean current & hot ocean current is favourable for growth of fisheries. Hence fishing industries flourish.

Also causes fog in nearby land disrupting transports.
